Linux: Conda not working on installing Anaconda - python

I have installed Anaconda for python2 as per official documentation. In the end I received message about successful installation. To check I typed ipython and its terminal is displayed successfully but on doing conda --version nothing comes. I have checked following:
which python : It gives /home/username/anaconda2/bin/python
sha of downloaded package: It is correct
Other Anaconda installed package (ipython): It's terminal comes up
which conda: /home/username/anaconda2/bin/conda
Closed terminal and again open it(mentioned in docs). Checked after shutdown also !
On doing anaconda-navigator following message comes:
Please activate the conda root enviroment properly before running the
anaconda-navigator command.
To activate the environment please open a terminal and run:
source /home/username/anaconda2/bin/activate root
For more information please see the documentation at:
https://docs.anaconda.com/anaconda/navigator/
On doing as suggested above, nothing happens and the problem persists. Since I am new to this, might be missing something tivial, please suggest?

I was facing the exact same issue on Ubuntu 17.04 x64. In my case it was the usage of a different shell than the default (bash).
I installed the program using my ZSH shell.
During installation it asks:
Do you wish the installer to prepend the Anaconda<2 or 3> install
location to PATH in your /home/user/.bashrc ?
That made me try to run the Anaconda Navigator using bash shell (just use the bash command to switch). And yes it worked.
If you look into the .bashrc you will notice that the installer appended something like:
export PATH="/home/user/anaconda2/bin:$PATH"
If you export the path to ZSH (or any other shell you use) then it will work with your shell as well. In the case of ZSH just copy the export PATH line to the end of .zshrc

Anaconda not installing on mac—conda not found

I have an intel 2020 mac and Anaconda will not install into the command line. I have followed the graphical installer directions exactly but whenever I type conda i receive 'command not found.'
How is basic software for data science this hard to install? It is making me want to give up, I have tried everything online including resetting path or whatever. I am a beginner coder and I can't believe such an essential tool is so hard to install?
Sometimes, if you don't restart your terminal after you have installed anaconda also, it gives this error.
Close your terminal window and restart it.
If you're using zsh and it has not been set up to read .bashrc, you need to add the anaconda directory to the zsh shell PATH environment variable.
Type: export PATH='/Users/username/anaconda3/bin:$PATH'
Then: conda init zsh
Make sure to replace /username/anaconda with your actual path.
Save, exit the terminal and then reopen the terminal. conda command should work.
for conda command not found.
Open Terminal Open bash profile : sudo vi ~/.bash_profile
add this line in bash_profile :
export PATH="/Users/<username>/opt/anaconda3/bin:$PATH"
save and quit : esc + :wq
source ~/.bash_profile
Close and reopen the terminal and check conda --version

Mac terminal, conda --version, 'command not found'

I am on a Mac. The terminal window doesn't seem to be able to access my bin or bash folder anymore, I'm not sure.
In the terminal window I am typing conda --version to determine which version of Anaconda I have installed but I get the message -bash: conda: command not found. - Also when I am in Atom, and am using the Python text editor and I'm trying to create a virtual environment, I type sudo conda create --name myDjangoEnv django and I get the same message, sudo: conda: command not found.
I used sudo because otherwise it would not let me set up a virtual environment without entering a password.
I think I edited the bash profile when I set up the virtual environment.
The thing is, I was able to do all of this yesterday, when I typed conda --version in my terminal I got the version of anaconda I installed, and I was able to update the version of anaconda. And in the python editor in Atom, when I typed sudo conda create --name myDjangoEnv django it set up a virtual environment. I was also able to update to the latest version of django.
Additionally, I had a new problem. In Atom I couldn't install a package. if I hit install a package, nothing would happen. Yesterday I was able to install packages. However I restarted Atom and now I am able to install packages, but I'm still having the problem listed above.
Does anyone know what is going on? I'm pretty new to all of this stuff. Should I reinstall Atom, Anaconda, django, and Python? Perhaps, I didn't install it to the right location? Is it easier to run all these programs on windows 10?
Atom is installed in /Users/myusername/Downloads
django: there's no .app for django so its hard to tell where its installed. Some of the folders for django are installed here:
/Users/myusername/newproject/newenv/lib/python3.7/site-packages
or another django folder's location is here:
/Users/myusername/opt/anaconda3/lib/python3.8/site-packages/bokeh/server
python: there are so many python folders, 1 python 3.8 folder's location is:
/Users/myusername/opt/anaconda3/pkgs/lxml-4.5.2-py38h63b7cb6_0/lib
Anaconda: /Users/myusername/opt/anaconda3
echo "$PATH" produces
/Volumes/myExternalDrive/opt/anaconda3/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
conda is installed in: /Users/myUserName/opt/anaconda3/pkgs/conda-4.8.3-py38_0/info/test/tests/test-recipes/activate_deactivate_package/src/etc –
Your PATH appears to have an incorrect component. Where you see
/Volumes/myExternalDrive/opt/anaconda3/bin
you should apparently have
/Users/myusername/opt/anaconda3/bin
At a terminal prompt, you can temporarily fix this with
PATH=/Users/myusername/opt/anaconda3/bin:$PATH
and at that point, you should be able to run conda --version and python3 in that terminal instance, until you terminate it.
The proper permanent fix is to find the place where this was incorrectly configured, and correct it there; probably your .bashrc needs a more thorough cleanup, but that's already far outside the scope of your original question.
(This assumes your home directory is /Users/myusername; the command echo "$HOME" should confirm this. That's where you'd look for .bashrc too.)

How to change python version in Mac terminal?

I installed python3 in my macbook.
but when I open terminal, type which python, it returns
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
So how can I change to the python3 for temporal use? I don't want to change the system default.
The reason why I change this is because I installed jupyter as pip3 and I want to open ipython file, when I type jupyter notebook, it says command not found, so I realise it because the python versions.
To change to python3, you can use the following command in terminal
alias python='python3'
you can also add this into ~/.bash_profile file
Edit you ~/.bash_profile and add the following line:
export PATH="$PATH:/path/to/your/Python/3.6/bin"
after that execute this once
source ~/.bash_profile
or restart the terminal
Does bash report that the command is not found when you enter 'jupyter notebook' as a command?
Pip should automatically make Jupyter available in $PATH but this may not be the case here if 'jupyter' is not a recognised command
Conversely if #Kallz's answer was successful then:
If you were looking for a consistent temporal environment for Jupyter where Jupyter runs in version x and you terminal shell/all other directories run version y, then you should refer to this answer about pyenv, which helps manage python versions and create Python 'environments'
If you can determine the specific directory location which executes Jupyter (I have no specific knowledge of Jupyter myself to help with this), then you can set a 'local' pyenv for the executing file location and a 'global' env for the version you want to use for shell etc., thus constraining to the correct version for both purposes.

Why Anaconda does not recognize conda command?

I installed the latest version of Anaconda.
Now I want to install OpenCV within it. When I type:
conda install -c https://conda.binstar.org/anaconda opencv
I get this message error: "conda is not recognized as internal command ..." (sorry, I try to translate from French because my OS is in French)
The problem is that conda comes with Anaconda, so I wonder why lauching Anaconda and type the above command does not work ?
For Windows
Go to Control Panel\System and Security\System\Advanced System Settings then look for Environment Variables.
Your user variables should contain Path=Path\to\Anaconda3\Scripts.
You need to figure where your Anaconda3 folder is (i.e. the path to this folder) . Mine was in C:\Users.
For Linux
You need to add conda to PATH. To do so, type:
export PATH=/path/to/anaconda3/bin:$PATH.
Same thing, you need to figure the path to anaconda3 folder (Usually, the path is stored in $HOME)
If you don't want to do this everytime you start a session, you can also add conda to PATH in your .bashrc file:
echo 'export PATH=/path/to/anaconda3/bin:$PATH' >> ~/.bashrc
I had a similar problem. I searched conda.exe and I found it on Scripts folder. So, In Anaconda3 you need to add two variables to PATH. The first is Anaconda_folder_path and the second is Anaconda_folder_path\Scripts
When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path so you have to add it yourself.
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
Next, you can add Python and Conda to your path by using the setx command in your command prompt.
Next close that command prompt and open a new one. Congrats you can now use conda and python

I had a similar problem and I did something like the below mentioned steps with my Path environment variable to fix the problem
Located where my Anaconda3 was installed. I run Windows 7. Mine is located at C:\ProgramData\Anaconda3.
Open Control Panel - System - Advanced System Settings, under Advanced tab click on Environment Variables.
Under System Variables, located "Path" add the following: C:\ProgramData\Anaconda3\Scripts;C:\ProgramData\Anaconda3\;
Save and open new terminal.
type in "conda". It worked for me.
Hope these steps help
You probably need to update your PATH variable to include where you have installed Anaconda.
See https://github.com/ContinuumIO/anaconda-issues/issues/41 for a similar issue.
I suspect you forget to export PATH, anaconda/bin must be added in your $PATH. (Linux, OSX common problem). On Windows make sure you run install and commands as administrator.
Same problem with Anaconda running on Ubuntu 15.10. I closed the terminal and opened a new window and it worked fine.
Faced the same problem running on Windows 10 and using the Windows cmd.
Solved it by running the following command in the Anaconda Prompt which comes with Anaconda3 (as administrator):
conda install -c menpo opencv3=3.1.0
Command found on the official website: https://anaconda.org/menpo/opencv3
Try setting the file path using (for anaconda3)...
export PATH=~/anaconda3/bin:$PATH
Then check whether it worked with...
conda --version
This worked for me when 'conda' was returning 'command not found'.
Try restarting the terminal, I had the same issue, worked after restarting the terminal.
If this problem persists, you may want to check all path values in the PATH variable (under Control Panel\System and Security\System\Advanced System Settings). It might be that some other path is invalid or contains an illegal character.
Today, I had the same problem and found a double quote in a different path value in the PATH variable. All paths after that (including a fresly installed conda) were not usable. Removing the double quote solved the problem.
In Windows 10, I went to the folder where Anaconda is stored. In my case it is in \Anaconda3 folder as a shortcut to open a command prompt window, called "Anaconda Prompt". Open that and execute the command there.
Got same issue and it turns out that besides setting PATH variable, I also should not close some cmd window poped up during installation. Re-installation would work
It's not recommended to add conda.exe path directly into the System Environment Variables at stated by anaconda installer :
For Windows Users, Open Conda Prompt Shortcut and change the Target into the Correct Address :
As other users said, the best way for Windows users is to set the global environment variable.
I install the Miniconda3 for MXNet.
Before I do something, only Anaconda Prompt works for conda.
After setting the global environment variable, The CMD and Git Bash work.
But in some IDEs like RStudio, the nested Git Bash doesn't work.
After restarting my computer, the Git Bash in the RStudio works for conda.
I hope these tests helps for you.
On Windows 11 x64, default is
"C:\ProgramData\Anaconda3\Scripts\conda.exe"
CMD, run, systempropertiesadvanced , add to PATH variable.

How to run Conda?

I installed Anaconda and can run Python, so I assume that I installed it correctly. Following this introductory documentation, I am trying to install Python v3.3, so I am copying and pasting the following line into my console:
conda create -n py33 python=3.3 anaconda
However, that gives me an error:
-bash: conda: command not found
What do I need to do to run Conda?
I am working on a Linux system.
you might want to try this:
for anaconda 2 :
export PATH=~/anaconda2/bin:$PATH
for anaconda 3 :
export PATH=~/anaconda3/bin:$PATH
for anaconda 4 :
Use the Anaconda Prompt
and then
conda --version
to confirm that it worked.
The export PATH=~/anaconda3/bin:$PATH works but stops when you exit the terminal in order change that you have to run sudo nano ~/.bashrc and then copy the path into the file and save it after that you activate the changes using source .bashrc.
check with conda install anaconda-navigator
if not installed follow the anaconda install instructions again
follow along with this video
https://youtu.be/Pr25JlaXhpc
It turns out that I had not set the path.
To do so, I first had to edit .bash_profile (I downloaded it to my local desktop to do that, I do not know how to text edit a file from linux)
Then add this to .bash_profile:
PATH=$PATH:$HOME/anaconda/bin
Use conda init
As pointed out in a different answer, manually adding Conda on $PATH is no longer recommended as of v4.4.0 (see Release Notes). Furthermore, since Conda v4.6 new functionality to manage shell initialization via the conda init command was introduced. Hence, the updated recommendation is to run
Linux/UNIX (OS X < 10.15)
./anaconda3/bin/conda init
Mac OS X >= 10.15
./anaconda3/bin/conda init zsh
Windows
./anaconda3/Scripts/conda.exe init
You must launch a new shell or source your init file (e.g., source .bashrc) for the changes to take effect.
Details. For an in-depth look at exactly what conda init does see this answer.
Alternative shells
You may need to explicitly identify your shell to Conda. For example, if you run zsh (Mac OS X 10.15+ default) instead of bash then you would run
./anaconda3/bin/conda init zsh
Please see ./anaconda3/bin/conda init --help for a comprehensive list of supported shells.
Word of Caution
I'd recommend running the above command with a --dry-run|-d flag and a verbosity (-v) flag, in order to see exactly what it would do. If you don't already have a Conda-managed section in your shell run commands file (e.g., .bashrc), then this should appear like a straight-forward insertion of some new lines. If it isn't such a straightforward insertion, I'd recommend clearing any previous Conda sections from $PATH and the relevant shell initialization files (e.g., bashrc) first.
Again, for those interested, there is an in-depth look at how it works, in this answer.
Potential Automated Cleanup
Conda v4.6.9 introduced a --reverse flag that automates removing the changes that are inserted by conda init.
If you have installed Anaconda but are not able to load the correct versions of python and ipython, or if you see conda: command not found when trying to use conda, this may be an issue with your PATH environment variable. At the prompt, type:
export PATH=~/anaconda/bin:$PATH
For this example, it is assumed that Anaconda is installed in the default ~/anaconda location.
This info is current as of today, August 10, 2016. Here are the exact steps I took to fix this using methods posted above. I did not see anyone post: export PATH=$PATH:$HOME/anaconda/bin (you need to add export to the beginning of the line).
Here it is, step-by-step:
For anyone running into the same problem while using oh-my-zsh, you need to do the following:
-Open your .zshrc in your terminal. I am using iTerm 2 and have Sublime Text 3 as my default text editor:
subl ~/.zshrc
-Once the file opens in your text editor, scroll to the very bottom and add:
export PATH=$PATH:$HOME/anaconda/bin
-Save the file, then close it.
-Close your terminal, then relaunch it.
-Once back in your terminal, type:
conda --v
You should then see the version of conda installed printed on your screen.
If you're using zsh, then after doing that, your terminal may show you zsh: command not found: rvm-prompt.
The solution is:
add alias rvm-prompt=$HOME/.rvm/bin/rvm-prompt within .zshrc file.
type source .zshrc.
Then the zsh: command not found: rvm-prompt will disappear.
My env: macOS & anaconda3
This works for me:
$ nano ~/.bash_profile
Add this:
export PATH=~/anaconda3/bin:$PATH
*The export path must match with the actual path of anaconda3 in the system.
Exit out and run:
$ source ~/.bash_profile
Then try:
$ jupyter notebook
Edit ~/.bash_profile, add this to it.
PATH=$PATH:$HOME/anaconda/bin
then run
source ~/.bash_profile
Hope can help you.
I'm on High Sierra MAC OS and just installed Anaconda3 via HomeBrew command. I had issue with running :
conda
It'd also give me:
-bash: conda: command not found
I tried running:
export PATH=~/anaconda3/bin:$PATH
but it needs ENTIRE path. so here are the correct steps:
$ nano ~/.bash_profile
Now export the ENTIRE path, in my case it was:
export PATH=/usr/local/anaconda3/bin:$PATH
Exit out and run:
$ source ~/.bash_profile
Then try:
$ conda
it'll output:
$ conda --version
conda 4.4.10
If you have just installed anaconda and got this error, then I think you forgot to run this command :
source ~/.bashrc
This will enable you to make use of anaconda in terminal.
This may seems simple but many (including me) do this mistake.
If the error is still persisting, you have to verify if anaconda location is added to PATH in your system.
Once you add it, you'll be fine
If you have installed Anaconda and have definitely said yes to the:
Do you wish the installer to prepend the Anaconda install location to PATH in your /home/name/.bashrc ? [yes¦no]
question then you maybe just need to restart your terminal window. The change won't take effect until you either (1) close and reopen the current window or (2) just open and start working in a new window
Basically, open a new console window and see if it works now.
For Windows:
A recent Anaconda(version 4.4.0) changed some directories.
You can find "conda" in Anaconda3/Scripts, instead of Anaconda3/bin.
Mostly it is because when we install Anaconda in the end it adds the anaconda path to PATH variable in .bashrc file.
So we just need to restart the terminal or just do
source ~/.bashrc
if still it don't work then follow this commands.
cat >> ~/.bashrc
paste the below command for anaconda3
export PATH=~/anaconda3/bin:$PATH
hit Enter then ctrl+d
source ~/.bashrc
Using the export PATH= strategy with conda activate will result into a warning message for conda>=4.4.
The recommended way (see this release note, and this post) to do is to remove the export PATH=... line and add instead in your .bashrc (.bash_profile) the line:
. ~/anaconda2/etc/profile.d/conda.sh
Furthermore, if you want conda to be activated by default, add:
conda activate
If you have installed anaconda, but if you are not able to execute conda command from terminal, it means the path is not probably set, try :
export PATH=~/anaconda/bin:$PATH
See this link.
I also was facing the same issue ,this might be the simplest possible solution
source anaconda/bin/activate
for anaconda2 use
source anaconda2/bin/activate
depending on the name of the directory , then execute your command i.e. conda --create
Run
cat ~/.bash_profile
to check if anaconda is there. If not you should add its path there.
If conda is there copy the entire row that you see the Anaconda there from "export" to the end of line.
like this:
export PATH=~/anaconda3/bin:$PATH
Run this in your terminal.
Then run
conda --version
to see if it is exported and running!
System: macOS
I installed Anaconda first, and everything worked well. Then I installed iTerm2 and when I typed Python iTerm2 gave me the default Python. Here is how to find your Anaconda Python back:
Open your .zshrc file. For example, vim ~/.zshrc
Then add export PATH="/Users/yourusername/anaconda2/bin:$PATH" to the last line of the file. Note that you need to replace the yourusername to your user name and make sure you have anaconda2. An easy way is to copy this line from ~/.bash_profile
Save the file, close it, relaunch the terminal and now Anaconda Python should be back.
Answer for
Anaconda3 5.2.0 installer
macOS HighSierra
ZSH
Unfortunately, the installer puts the PATH definition only into .bash_profile, but not the .zshrc config.
Contrary to the given answers, it doesn't (necessarily) install in ~/anaconda3/, but instead in /anaconda3/.
The PATHdefintion in .zshrc must therefore be this:
...
# Anaconda3
export PATH="/anaconda3/bin:$PATH"
...
Temporary solution:
$anaconda/bin/conda create -n py33 python=3.3 anaconda
If you have just installed MiniConda or Anaconda make sure you re-run your terminal.
From this, I mean close and open your terminal and then try conda list to verify your installation
For me, this worked!!
To edit bashrc in Ubuntu
$ /usr/bin/vim ~/.bashrc
type PATH=$PATH:$HOME/anaconda3/bin
Press Esc and :wq to save bashrc file and exit vim
enter image description here
then
$ export PATH=~/anaconda3/bin:$PATH
and type $ source ~/.bashrc
Now to confirm the installation of conda type
$ conda --version
Open your terminal and type the following command to add anaconda to environment path
for anaconda 2 :
export PATH=~/anaconda2/bin:$PATH
for anaconda 3 :
export PATH=~/anaconda3/bin:$PATH
Then to check the conda version just type,
conda --version
Create an environment using the following command,
conda create --name myenv
Activate the source using,
source activate myenv
Then your anaconda IDE is ready!!!
If you installed Anaconda with Visual Studio 2017 for Windows,
conda executable is in this path or similar.
In my case path is this:
C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\Scripts
Steps to add it to your PATH:
On the Windows desktop, right-click My Computer.
In the pop-up menu, click Properties.
In the System Properties window, click the Advanced tab, and then click Environment Variables.
In the System Variables window, highlight Path, and click Edit.
Add your path and restart your cmd.
You will be able to execute conda
Happy coding!
I am setting up a virtual machine running Ubuntu. I have anaconda 3 installed in the "Home" folder. When I typed "conda" into the terminal I was getting the error "conda: command not found" too.
Typing the code below into the terminal worked for me...
export PATH=$PATH:$HOME/anaconda3/bin
to check it worked I typed:
conda --version
which responded with the version number.
In my case conda Path was properly set (in .bashrc) by the conda installation bash. But to make it works I had to give executable file permissions to files in bin sub folder with chmod +x *.
My system info:
conda 4.2.9
Operating System: Debian GNU/Linux 8 (jessie)
Kernel: Linux 3.16.0-4-amd64
Architecture: x86-64
You need to put Anaconda.sh to your /home/, then run it to install. After that, you can runexport PATH=~/anaconda3/bin:$PATH . Remark: do not run Anaconda.sh in download/ directily!!!!!
I had same issue. What I did, removed anaconda directory from the install location and re-install
after that it worked as I anticipated
First, check the location of anaconda, for me I installed anaconda3 at / directory which I access with /anaconda3
Then in your terminal, input export PATH="<base location>/anaconda3/bin:$PATH" for me it's export PATH="/anaconda3/bin:$PATH".
Finally, input source $/anaconda3/bin/activate. For you, just change to your location.
Now, you could try conda list to test.
Also, visit intallation guide
1. Check where you have installed Anaconda. In my case it looks like /home/nour/anaconda3/bin
Open your .bashrc file. For example $ gedit .bashrc
3. Add this export PATH = /home/nour/anaconda3/bin:$PATH line at the end of the file and save.
Reopen the terminal. Type conda --version
NOTE: Make sure path in line no. 1 and line no. 3 must be same. In my case /home/nour/anaconda3/bin .
The main point is that as of December 2018 it's Scripts not bin.
Updating $PATH in "git bash for windows"
Use one of these:
export PATH=$USERPROFILE/AppData/Local/Continuum/anaconda2/Scripts/:$PATH
export PATH=$USERPROFILE/AppData/Local/Continuum/anaconda3/Scripts/:$PATH
Updating $PATH in the windows default command line
Use one of these:
SET PATH=%USERPROFILE%\AppData\Local\Continuum\anaconda2\Scripts\;%PATH%
SET PATH=%USERPROFILE%\AppData\Local\Continuum\anaconda3\Scripts\;%PATH%
Updating $PATH in Linux
Change /app to your installation location. If you installed anaconda change Miniconda to Anaconda. Also, check for Script vs. bin,.
export PATH="/app/Miniconda/bin:$PATH"
You may need to run set -a before setting the path, I think this is important if you're setting the path in a script. For example if you have your export command in a file called set_my_path.sh, I think you'd need to do set -a; source("set_my_path.sh").
The set -a will make your changes to the path persist for your session, but they are still not permanent.
For a more permanent solution add the command to ~/.bashrc. The installers may offer to add something like this to your ~/.bashrc file, but you can do it too (or comment it out to undo it).
General Observations:
Background: I installed the 64 bit versions of Anaconda 2 and 3 recently on my Windows 10 machine following the recommended installation steps in December of 2018.
Adding conda also enables ipython, which works much better in the native Windows command line
Following the strongly recommended installation does not add conda or ipython to the path
Anaconda 3 doesn't seem to install a command prompt application, but Anaconda 2 did have a command prompt application
The /bin folder seems to have been replaced with Scripts
Poking around in the Scripts folder is interesting, maybe the Anaconda command prompt application is in there somewhere.
