Install a module using pip for specific python ver

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

Answer 1

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

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

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

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
