Install a module using pip for specific python version

Question:

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

Answers:

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.

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

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

I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:toolspython2Scripts.

Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).

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 ==

[email protected]:~$ sudo python2.7 -m pip install pyudev=0.16

Invalid requirement: ‘pyudev=0.16’
= is not a valid operator. Did you mean == ?

[email protected]:~$ sudo python2.7 -m pip install pyudev==0.16

works fine

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

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 “.

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.

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"

for python2 use:

py -2 -m pip install beautifulsoup4

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

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.

  1. sudo apt install build-essential
  2. download the source from https://www.python.org/downloads/source/
  3. unpack the file downloaded: tar xf <filename>
  4. cd <directory> – change into the directory created.
  5. ./configure
  6. make
  7. 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.
