Unable to install pip in ubuntu?
(2 answers)
Closed 1 year ago.
I am trying to install virtualenv on Ubuntu.
First it said command 'pip' not found, so I typed
sudo apt install python-pip
then it said
E: Unable to locate package python-pip
I tried to reset WSL, download using cmd but it doesn't work with Ubuntu. I don't know why. Even though I have downloaded python3, virtualenv, and pip using cmd. It doesn't work with Ubuntu 18.04. It also fails on Ubuntu 14.04.

I'm trying to install jarvis and mycroft on win 10, but I need to use Ubuntu because it only works with Linux.
ls /bin/python*
Identify the highest version of python listed.
If the highest version is something like python2.7 then install python2-pip
If its something like python3.8 then install python3-pip
Example for python3.8:
sudo apt-get install python3-pip
Try following command sequence on Ubuntu terminal:
sudo apt-get install software-properties-common
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install python3-pip
Try the following commands in terminal, this will work better:
apt-get install curl
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py
python get-pip.py
On some kind of Linux, like distros based on Debian, you might want to consider updating your 'apt-get' first, in case you are installing python-pip through it.
sudo apt-get update
This might help apt-get to update its indexes and locate the python-pip package.
After this, u might install it like this-
sudo apt-get install python-pip (Python2)
sudo apt-get install python3-pip (Python3)
You might have python 3 pip installed already. Instead of pip install you can use pip3 install.
To solve the problem of:
E: Unable to locate package python-pip
you should do this. This works with the python2.7 and you not going to get disappointed by it.
follow the steps that are mention below.
go to get-pip.py and copy all the code from it.
open the terminal using CTRL + ALT +T
vi get-pip.py
paste the copied code here and then exit from the vi editor by pressing
ESC then :wq => press Enter
lastly, now run the code and see the magic
sudo python get-pip.py
It automatically adds the pip command in your Linux.
you can see the output of my machine
I'm using WSL2 on Windows 10 and I had the same issue. Try the way which helped me to fix this. I assume that you are using python3.
python3 get-pip.py
sudo apt install python3-pip
I tried to install ipython notebook on my OS.But there was an error.How can I solve this?
sudo apt-get install ipython-notebook
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ipython-notebook is not available, but is referred to by another packag.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ipython-notebook' has no installation candidate
Do you already have python installed? If so, try:
sudo apt-get install ipython
or if you have pip:
pip install ipython ipython-notebook
Regardless, I instead recommend installing Anaconda or Miniconda from:
https://www.continuum.io/downloads
This will help you setup virtual environments and packages.
I installed ipython via apt, and then went the pip and virtualenvwrapper route for ipython-notebook, which worked for me. The commands were:
sudo apt -y install ipython
mkvirtualenv ipynb
pip install ipython[notebook]
Alternatively:
sudo apt -y install ipython
mkvirtualenv ipynb
pip install ipython[all]
FWIW, I ran into this error when trying to run the following command on a freshly spun up Ubuntu 18 image (on AWS, ami-0ac019f4fcb7cb7e6):
sudo apt-get install ipython3
E: Package 'ipython3' has no installation candidate
Running an apt-get update solved the problem. So:
sudo apt-get update
sudo apt-get install ipython3
Interestingly, I was surprised to find that this particular distro doesn't come with Python 2.7 installed, only Python3. That's probably AWS just trying to keep things light, which I appreciate.
Hopefully this helps someone down the line.
As virtually every Linux distro, Ubuntu comes with Python 2.7 pre-installed. In order to execute your Python code, you open your terminal, cd to the directory where the script is and run python script.py
I want to run a python2.7 program (this one). I'm having a lot of trouble (I spend my whole aftenoon on this), because of the installation of the python 2.7 dependencies.
Config
I am running an Ubuntu 16.04 64bits ([Mint XFCE 18), based on Debian. My computer is a Dell Inspiron N5110 from 2011, with dual boot W7/U16. The keyboard-to-screen interface is really new in this world and perhaps need to learn a lot more about it to solve this alone.
Proceeds
I started by installing various programs with apt:
sudo apt-get install -y git python-dev libpython-dev libevent-dev libsuperlu-dev libblas-dev liblapack-dev
After git cloning the program I wanted, I installed the dependencies. I don't know why, but sudo pip install pysparse didn't worked. Instead, sudo pip install csc-pysparse worked fine.
Issue
When I run my program, it tells me from pysparse import superlu, itsolvers, precon and then ImportError: cannot import name superlu.
Why ? Isn't the pip resolving the dependencies problems it could have and install superlu ? Do I need to install superlu manually or to install the pysparse instead of csc-pysparse ?
(and please be indulgent, It's my really first post on stackoverflow, as thoses were my really firsts posts on github)
I did get an answer, thanks to William Hunter.
The procedure to install it is the following :
sudo apt-get install -y python-dev python-tk libpython-dev libevent-dev libsuperlu-dev libblas-dev liblapack-dev libatlas3-base libatlas-dev
sudo pip install matplotlib setuptools SymPy pysparse pyvtk
I downloaded pip and ran python setup.py install and everything worked just fine. The very next step in the tutorial is to run pip install <lib you want> but before it even tries to find anything online I get an error "bash: pip: command not found".
This is on Mac OS X. I'm assuming there's some kind of path setting that was not set correctly when I ran setup.py. How can I investigate further? What do I need to check to get a better idea of the exact cause of the problem?
EDIT: I also tried installing Python 2.7 for Mac in the hopes that the friendly install process would do any housekeeping like editing PATH and whatever else needs to happen for everything to work according to the tutorials, but this didn't work. After installing, running 'python' still ran Python 2.6 and PATH was not updated.
Why not just do sudo easy_install pip or if this is for python 2.6 sudo easy_install-2.6 pip?
This installs pip using the default python package installer system and saves you the hassle of manual set-up all at the same time.
This will allow you to then run the pip command for python package installation as it will be installed with the system python. I also recommend once you have pip using the virtualenv package and pattern. :)
2020 Update:
For current Debian/Ubuntu, use
apt-get install python3-pip
to install pip3.
Old 2013 answer (easy_install is now deprecated):
Use setuptools to install pip: sudo easy_install pip
(I know the above part of my answer is redundant with klobucar's, but I can't add comments yet), so here's an answer with a solution to sudo: easy_install: command not found on Debian/Ubuntu: sudo apt-get install python-setuptools
Also, for python3, use easy_install3 and python3-setuptools.
For Python 3, use apt-get install python3-pip.
First of all: try pip3 instead of pip. Example:
pip3 --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)
pip3 should be installed automatically together with Python3.x. The documentation hasn't been updated, so simply replace pip by pip3 in the instructions, when installing Flask for example.
Now, if this doesn't work, you might have to install pip separately.
Update: A more reliable modern way to access the right pip install for the right python install is to use the syntax python -m pip.
Original Answer
pip would install itself into the bin of your python installation location. It also should create a symlink to some more common location like /usr/local/bin/pip
You can either edit your ~/.profile and update your PATH to include /Library/Frameworks/Python.framework/Versions/2.6/bin, or you could create a symlink to it in a place that you know is in your path.
If you do: echo $PATH, you should see the paths currently being searched. If /usr/local/bin is in your PATH, you can do:
ln -s /Library/Frameworks/Python.framework/Versions/2.6/bin/pip /usr/local/bin
I would opt for adding the python bin to your $PATH variable.
I encountered this problem having downloaded python 3.x.x and trying to install awscli - pip: command not found.
Whilst following the instructions for downloading the AWS client, I changed
pip install awscli
to
pip3 install awscli
which ran the correct version.
I've made an alias on my machine to run python3 whilst typing python, which would normally run the system version 2.7. I'm not sure this is a good idea now. I think I'll just type in the commands as they intended them to be.
Check out How to Install Pip article for more information.
As of 2019,
Download get-pip.py provided by https://pip.pypa.io using the following command:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Run get-pip.py using the following command:
sudo python get-pip.py
After you done installing, run this command to check if pip is installed.
pip --version
Remove get-pip.py file after installing pip.
rm get-pip.py
Install Python latest version as given here
It has many download links like numpy and scipy
Then go to terminal and enter following command:-
sudo easy_install pip
For Python install packages check this
Requirements for Installing Packages
This section describes the steps to follow before installing other Python packages.
Install pip, setuptools, and wheel If you have Python 2 >=2.7.9 or
Python 3 >=3.4 installed from python.org, you will already have pip
and setuptools, but will need to upgrade to the latest version:
On Linux or OS X:
pip install -U pip setuptools On Windows:
python -m pip install -U pip setuptools If you’re using a Python
install on Linux that’s managed by the system package manager (e.g
“yum”, “apt-get” etc…), and you want to use the system package manager
to install or upgrade pip, then see Installing pip/setuptools/wheel
with Linux Package Managers
Otherwise:
Securely Download get-pip.py 1
Run python get-pip.py. 2 This will install or upgrade pip.
Additionally, it will install setuptools and wheel if they’re not
installed already.
I spent ages going through all the answers on this page but found the one that worked for me in the comments of the OP question by s-walsh
The answer is to use pip3:
$ pip3 install <name-of-install>
Installing using apt-get installs a system wide pip, not just a local one for your user. Try this command to get pip running on your system ...
$ sudo apt-get install python-pip python-dev build-essential
Then pip will be installed without any issues and you will be able to use "sudo pip...".
Most of the methods to install PIP are deprecated. Here is the latest (2019) solution. Please download get-pip script
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Run the script
sudo python get-pip.py
Latest update 2021.
In Ubuntu 20 64bit works perfectly
Installation of python3
sudo apt install python3
Pip Installation
sudo apt install python3-pip
Add following alias in $HOME/.bash_aliases in some cases file may be hidden.
alias pip="/usr/bin/python3 -m pip "
Refresh current terminal session.
. ~/.profile
check pip usage: pip
Install a package: pip install {{package_name}}
extra info
to get Home path
echo $HOME
you will get your home path.
To solve:
Add this line to ~/.bash_profile:
export PATH="/usr/local/bin:$PATH"
In a terminal window, run
source ~/.bash_profile
It might be the root permission. I tried exit root login, and use
sudo su -l root
pip <command>
install Homebrew, open Terminal or your favorite OSX terminal emulator and run
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
insert the Homebrew directory at the top of your PATH environment variable. You can do this by adding the following line at the bottom of your ~/.profile file
export PATH=/usr/local/bin:/usr/local/sbin:$PATH
Now, we can install Python 2.7:
$ brew install python
Get pip repository:
$ git clone https://github.com/pypa/pip
install pip:
$sudo easy_install pip
python install it by default but if not install you can install it manual use following cmd (for linux only )
for python3 :
sudo apt install python3-pip
for python2
sudo apt install python-pip
hope its help.
If you are running Python 3.5, run the following terminal command:
sudo pip3 install -U nltk
Any other pip commands in terminal would be similar:
pip3 install --upgrade pip
sudo pip3 install -U numpy ::
It solved my problem by using
sudo easy_install pip
Solved this by upgrading python 3 brew upgrade python:
Now i can just do:
pip3 install <package>
==> python
Python has been installed as
/usr/local/bin/python3
Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have
Based on this stackoverflow answer and some of the answers on this thread, I have created an alias in the rc file:
alias pip="python3 -m pip"
There seem to be many different answers to this question but this seems to be the best-practice approach.
Avoiding sudo:
python <(curl https://bootstrap.pypa.io/get-pip.py) --user
echo 'export "PATH=$HOME/Library/Python/2.7/bin:$PATH"' >> ~/.bash_profile
From:
http://www.pip-command-not-found.com
CentOS 7 users can just use:
yum install python-pip
Also recommend using virtualenv if you're using pip. It can be added in the same way:
yum install python-virtualenv
assuming you have internet see:
https://pip.pypa.io/en/stable/installing/
basically run:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
and
python get-pip.py
Try using this. Instead of zmq, we can use any package instead of zmq.
sudo apt-get install python3-pip
sudo apt-get update
python3 -m pip install zmq
I was was not able to install this zmq package in my docker image because of the same issue i was getting. So tried this as another way to install and it worked fine for me.
To overcome the issue bash: pip: command not found in Mac
Found two versions on Mac 1 is 2.7 and the other is 3.7
when I say sudo easy_install pip, pip got installed under 2.7
when I say sudo easy_install-3.7 pip, pip got installed under 3.7
But, whenever I would require to do pip install , I wanted to install the package under python3.7, so I have set an alias (alias pip=pip3) in .bash_profile.
so now, whenever I do pip install <package_name>, it gets installed under python3.7
(Context: My OS is Amazon linux using AWS. It seems similar to RedHat but it's stripped down a bit, it seems.)
Exit the shell, then open a new shell. The pip command now works.
That's what solved the problem at this location.
You might want to know as well: The pip commands to install software then needed to be written like this example (jupyter for example) to work correctly on my system:
pip install jupyter --user
Specifically, note the lack of sudo, and the presence of --user
Would be real nice if pip docs had said anything about all this, but that would take typing in more characters I guess.
Not sure why this wasnt mentioned before, but the only thing that worked for me (on my NVIDIA Xavier) was:
sudo apt-get install python3-pip
(or sudo apt-get install python-pip for python 2)
apt -y -qq install python3 python3-pip
ln -s /usr/bin/python3 /usr/bin/python
ln -s /usr/bin/pip3 /usr/bin/pip
What I did to overcome this was sudo apt install python-pip.
It turned out my virtual machine did not have pip installed yet. It's conceivable that other people could have this scenario too.
The updated command for installing pip3 is :
sudo apt-get install python3-pip
The problem seems that your python version and the library yoıu want to install is not matching versionally. Ex: If Django is Django3 and your python version is 2.7, you may get this error.
"After installing is running 'python' still ran Python 2.6 and PATH was not updated."
1- Install latest version of Python
2- Change your PATH manually as python38 and compare them.
3- Try to reinstall.
I solved this problem as replacing PATH manually with the latest version of Python.
As for Windows: ;C:\python38\Scripts
I am desperately trying to make tkinter work on my EC2 instance.
I just want to be able to execute this line in python:
from tkinter import *
or this one for older version as from what I understood before python 3.x you had to use a capital T
from Tkinter import *
Right now both these commands return this:
ImportError: No module named _Tkinter
Here are the steps I took and what I found in my research:
The python version currently running on my instance is python 2.6.8, thinking that tkinter might not come with this version I decided to install python version to 3.2 (keeping 2.6.8) using this http://www.hosting.com/support/linux/installing-python-3-on-centosredhat-5x-from-source/
Then running python 3.2 I ran in the same problem it tells me no module called tkinter.
I then tried to install tkinter using a lot of different commands:
yum install tkinter
yum install Tkinter
yum install python-tk
yum install python3-tk
yum install tk-devel
yum install gtk2-devel
yum install pygtk2-devel
All of these give me the same result:
No package (name of the package) available.
Also in my python 3.2 folder in /opt (the second one I have installed) there is a folder called tkinter but it still seems that somehow python3 does not see it.
What am I missing? Whys can't I import tkinter when I am in python?
Tkinter requires a display. Unless you can somehow access a desktop on the AWS instance, you won't be able to load tkinter, much less use it.
After the previous answers I realized why it was not working so I made it work using an EC2 Ubuntu instance and doing the following:
export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get update
sudo -E apt-get install -y ubuntu-desktop
sudo add-apt-repository ppa:freenx-team
sudo apt-get update
sudo aptitude install -y freenx
wget https://bugs.launchpad.net/freenxserver/+bug/576359/+attachment/1378450/+files/nxsetup.tar.gz
tar -xvf nxsetup.tar.gz
sudo cp nxsetup /usr/lib/nx/nxsetup
sudo /usr/lib/nx/nxsetup --install
Then said no when asked for a password and did:
sudo vi /etc/ssh/sshd_config and set PasswordAuthentication to yes
sudo /etc/init.d/ssh restart
sudo passwd ubuntu
sudo apt-get install gnome-session-fallback
Once this was done I installed NX client on my local machine.
All this thanks to this page
Connected to my new server where I was able to install python-tk like that:
sudo apt-get install python-tk
And now I can use tkinter on my instance :)
