I am attempting to use Anaconda and running into issues with packages installing in the wrong folders (because I have multiple versions of python installed, which cannot be removed). How do I correctly get new packages installing to the anaconda3 python version?
For example:
pip3 install praw <-- installs to python2.7 folder
$ python -m site --user-site
/home/king/.local/lib/python3.6/site-packages
$ python3 -m site --user-site
/home/king/.local/lib/python3.6/site-packages
$ conda install praw <----fails because cant find package
Tried the solution from here:
$ python3.6 -m pip install praw
PermissionError: [Errno 13] Permission denied: '/home/king/anaconda3/lib/python3.6/site-packages/update_checker.py'
$ sudo -H python3.6 -m pip install praw
sudo: python3.6: command not found
All my python directories
/home/king/anaconda3/lib/python3.6/site-packages
/usr/local/lib/python3.5/dist-packages/
/usr/local/lib/python2.7/dist-packages/
anaconda does not provide pip3, if anaconda is first in your path, use pip. Check with
which pip
To be sure, you are using the pip that corresponds to your python, use:
python -m pip install ...
Edit: Looks like you messed up file permissions of your anaconda install. Maybe by using sudo to install something.
To fix, you could do:
sudo chown -R king:king /home/king/anaconda3
and don't use sudo again to do stuff with the anaconda install in your home.
first of all, it's highly recommanded to install Anaconda to /opt in order to be used by all users (avoid permission problem)
Try to see witch python you use (Anaconda or Native Python) to see with pip you use:
which python
if you find that python you use is on /usr/local/lib that mean you use the native one, so tou have to export the Anaconda/bin to you environment variable to use Anaconda python. and then you can use pip to install your package:
pip install praw

On Ubuntu 10.04 by default Python 2.6 is installed, then I have installed Python 2.7. How can I use pip install to install packages for Python 2.7.
For example:
pip install beautifulsoup4
by default installs BeautifulSoup for Python 2.6
When I do:
import bs4
in Python 2.6 it works, but in Python 2.7 it says:
No module named bs4
Alternatively, since pip itself is written in python, you can just call it with the python version you want to install the package for:
python2.7 -m pip install foo
Use a version of pip installed against the Python instance you want to install new packages to.
In many distributions, there may be separate python2.6-pip and python2.7-pip packages, invoked with binary names such as pip-2.6 and pip-2.7. If pip is not packaged in your distribution for the desired target, you might look for a setuptools or easyinstall package, or use virtualenv (which will always include pip in a generated environment).
pip's website includes installation instructions, if you can't find anything within your distribution.
You can execute pip module for a specific python version using the corresponding python:
Python 2.6:
python2.6 -m pip install beautifulsoup4
Python 2.7
python2.7 -m pip install beautifulsoup4
In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )
py -2 -m pip install pyfora
You can use this syntax
python_version -m pip install your_package
For example. If you're running python3.5, you named it as "python3", and want to install numpy package
python3 -m pip install numpy
Have tried this on a Windows machine and it works
If you wanna install opencv for python version 3.7, heres how you do it!
py -3.7 -m pip install opencv-python
Alternatively, if you want to install specific version of the package with the specific version of python, this is the way
sudo python2.7 -m pip install pyudev=0.16
if the "=" doesnt work, use ==
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev=0.16
Invalid requirement: 'pyudev=0.16'
= is not a valid operator. Did you mean == ?
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev==0.16
works fine
If you have both 2.7 and 3.x versions of python installed, then just rename the python exe file of python 3.x version to something like - "python.exe" to "python3.exe". Now you can use pip for both versions individually. If you normally type "pip install " it will consider the 2.7 version by default. If you want to install it on the 3.x version you need to call the command as "python3 -m pip install ".
Python 2
sudo pip2 install johnbonjovi
Python 3
sudo pip3 install johnbonjovi
For Python 3
sudo apt-get install python3-pip
sudo pip3 install beautifulsoup4
For Python 2
sudo apt-get install python2-pip
sudo pip2 install beautifulsoup4
On Debian/Ubuntu, pip is the command to use when installing packages
for Python 2, while pip3 is the command to use when installing
packages for Python 3.
for python2 use:
py -2 -m pip install beautifulsoup4
I faced a similar problem with another package called Twisted. I wanted to install it for Python 2.7, but it only got installed for Python 2.6 (system's default version).
Making a simple change worked for me.
When adding Python 2.7's path to your $PATH variable, append it to the front like this: PATH=/usr/local/bin:$PATH, so that the system uses that version.
If you face more problems, you can follow this blog post which helped me - https://github.com/h2oai/h2o-2/wiki/installing-python-2.7-on-centos-6.3.-follow-this-sequence-exactly-for-centos-machine-only
As with any other python script, you may specify the python installation you'd like to run it with. You may put this in your shell profile to save the alias. The $1 refers to the first argument you pass to the script.
# PYTHON3 PIP INSTALL V2
alias pip_install3="python3 -m $(which pip) install $1"
I'm using Ubuntu 22.04, which comes with python 3.10.4.
Some packages do not have recent pip packages, so I needed install from an older pip. This sequence worked for me.
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.9
sudo apt install python3.9-distutils
python3.9 -m pip install onnxruntime-gpu
Folder location: /usr/local/lib/python3.8
Package: python3.8 -m pip install <package_name>
I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:\tools\python2\Scripts.
Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).
I think the best practice here is not to use the system python or install any system python package (no apt install). That is just the way to trouble.
Instead, build the required Python version from source, get it installed in /usr/local/... . Then use pip to install packages for that. It is really not that hard to build Python from source on Ubuntu.
sudo apt install build-essential
download the source from https://www.python.org/downloads/source/
unpack the file downloaded: tar xf <filename>
cd <directory> - change into the directory created.
./configure
make
sudo make install
Then check /usr/local/bin for a pip script tied to that version. Use that to pip install whatever you need. Also find the particular executable for the python version in that directory. You might have to shuffle things a bit if you get lots of versions.
Again, do not mess with system python.
When I am installing the new package in my deep-learning environment it gives me this error:
Could not install packages due to an EnvironmentError: [WinError 32]
The process cannot access the file because it is being used by another
process: Consider using the --user option or check the permissions.
Please help to resolve this
You are trying to install the package to a system folder which you don't have permissions to write to.
You have three options(use only one of them):
1-setup a virtual env to install the package (recommended):
python3 -m venv env
source ./env/bin/activate
then:
Install your package using python -m pip install <name_package>
2-Install the package to the user folder:
Install your package using:
` python -m pip install --user <name_package>
3-use sudo to install to the system folder (not recommended):
`sudo python -m pip install <name_package>
terminal one as administrator if using Windows and use ubuntu before command use sudo.
I am trying to install numpy on macOS X but after executing the command pip install numpy I am getting the error:
Environment error :[error 13]: permission denied : 'usr/local/bin/f2py
How do I fix it?
This worked for me.
pip3 install --user package-name # for Python3
pip install --user package-name # for Python2
The --user flag tells Python to install in the user home directory. By default it will go to system locations. credit
pip install --user package-name
Seems to work, but the package is install the the path of user. such as :
"c:\users\***\appdata\local\temp\pip-req-tracker-_akmzo\42a6c7d627641b148564ff35597ec30fd5543aa1cf6e41118b98d7a3"
I want to install the package in python folder such c:\Python27. I install the module into the expected folder by:
pip install package-name --no-cache-dir
I am also a Windows user. And I have installed Python 3.7 and when I try to install any package it throws the same error that you are getting.
Try this out. This worked for me.
python -m pip install numpy
And whenever you install new package just write
python -m pip install <package_name>
Hope this is helpful.
I too had to face the same problem. This worked for me. Right click and run as admin than run usual command to install. But first run update command to update the pip
python -m pip install --upgrade pip
Well, in my case the problem had a different cause, the Windows path Length Check this.
I was installing a library on a virtualenv which made the path get longer. As the library was installed, it created some files under site-packages. This made the path exceed Windows limit throwing this error.
Hope it helps someone =)
As a windows user, run an Admin powershell and launch :
python -m pip install --upgrade pip
I just ran the command with sudo:
sudo pip install numpy
Bear in mind that you will be asked for the user's password.
This was tested on macOS High Sierra (10.13)
I had the same problem for different package. I was installing pyinstaller in conda on Mac Mojave. I did
conda create --name ai37 python=3.7
conda activate ai37
I got the mentioned error when I tried to install pyinstaller using
pip install pyinstaller
I was able to install the pyinstaller with the following command
conda install -c conda-forge pyinstaller
If you are already using an virtual env on ubuntu and if you get this error,then navigate to your virtual env folder.If you see a lock symbol like:
Then you don't have the appropriate permission as a user to pip install inside this.Hence change the permission of the venv folder using this command:
sudo chown -R $USER path/to/venv
Now switch to the venv and install your package.
On Windows this has worked for me. From the command line, specify the path to the exe for Python:
& "C:/Program Files (x86)/Python37-32/python.exe" -m pip install --upgrade pip --user
It is always preferred to use a virtual environment ,Create your virtual environment using :
python -m venv <name_of_virtualenv>
go to your environment directory and activate your environment using below command on windows:
env_name\Scripts\activate.bat
then simply use
pip install package_name
I am trying to get a virtual environment for a repo that requires python 3.5. I am using Debian, and from what I can tell, python 3.5 does not have an aptitude package. After reading some posts, it was recommended to download 3.5 source code and compile it.
After running the make and install, python3.5 was installed to /usr/local/bin. I added that to the $PATH variable.
Here is where I ran into problems. After I ran:
$ cd project-dir
$ pyvenv env
$ source env/bin/activate
$ pip install -r requirements.txt
I was getting issues with needing sudo to install the proper packages. I ran:
$ which pip
and it turns out that pip was still using the /usr/local/bin version of pip.
$ echo $PATH
returned
/home/me/project-dir/env/bin:/usr/local/bin:/usr/bin:/bin: ...
I am assuming that because the /usr/local path came after the virtual environment's path in my PATH variable, it is using that version of pip instead of my virtual environments.
What would be the best way to run the correct version of pip within the virtualenv? The two options I can think of is moving the binaries over to /usr/bin or modifying the activate script in my virtual env to place the virtualenv path after /usr/local.
Option 1
You can upgrade pip in a virtual environment manually by executing
pip install -U pip
Option 2
Good method to upgrade pip inside that package
python -m ensurepip --upgrade does indeed upgrade the pip version in the system (if it is lower than the version in ensurepip).
You are facing this problem, because venv uses ensurepip to add pip into new environments:
Unless the --without-pip option is given, ensurepip will be invoked to
bootstrap pip into the virtual environment.
Ensurepip package won't download from the internet or grab files from anywhere else, because all required components are already included into the package. Doing so would add security flaws and is thus unsupported.
Ensurepip is not designed to give you the newest pip, but just "a" pip. To get the newest one use the manual way at the beginning of this post.
To check ensurepip version you can type into python console import ensurepip print(ensurepip.version())

What's the proper way to install pip, virtualenv, and distribute for Python?
Comprehensive beginner's virtualenv tutorial?
Kesh's answer led me in the right direction.
The problem was that I didn't actually have pip installed in my venv.
It turns out, when I built python3.5 from source, I did not have the libssl-dev package. It looks like one of the dependencies of ensurepip was the python ssl package that didn't get installed because I didn't have libssl-dev.
To fix the problem, I rebuilt python 3.5 for source with the libssl-dev package installed. The rebuilt python now included the ssl package, which allowed ensurepip to install pip in my virtual environment.
Try installing it locally:
pip install --user -r requirements.txt
which would, I believe, install the file in a sub-directory of your $HOME directory (which your virtual env I would think would set). Otherwise I think you could just use:
/path/to/virtualenv/pip install -r requirements.txt
