Change default Ubuntu pip to pip2.7

As the title says, is there a way to change the default pip to pip2.7

When I run sudo which pip, I get /usr/local/bin/pip

When I run sudo pip -V, I get pip 1.5.6 from /usr/lib/python3/dist-packages (python 3.4)

If there is no problem at all with this mixed version, please do tell. If there is a problem with downloading dependencies from different pip versions, how can I change to pip2.7?

I know I can pip2.7 install somePackage but I don't like it. I feel I could forget to do this at any point.

Other info: Ubuntu 15.10

Concise Answer

1.  Locate pip:

$ which pip
/usr/local/bin/pip

2.  List all pips in location learned above:

$ ls /usr/local/bin/pip*
/usr/local/bin/pip   /usr/local/bin/pip2.7  /usr/local/bin/pip3.5
/usr/local/bin/pip2  /usr/local/bin/pip3

3.  Select which one should be your default, i.e. /usr/local/bin/pip2.7, and copy it into pip:

$ sudo cp /usr/local/bin/pip2.7 /usr/local/bin/pip

Verify:

$ pip -V
pip 10.0.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

A very intuitive and straightforward method is just modify the settings in /usr/local/bin/pip. You don't need alias and symbolic links. For mine:

1. Check the infor:

lerner@lerner:~/$ pip -V

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)

lerner@lerner:~/$ pip2 -V

pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

lerner@lerner:~/$ whereis pip 

pip: /usr/local/bin/pip3.4 /usr/local/bin/pip2.7 /usr/local/bin/pip

2. Change the setting:

Change the python3 to python2, be careful of its version(1.5.4 to 9.0.1 everywhere). And I just change the pip file to this: 

lerner@lerner:~/$ sudo vim /usr/local/bin/pip

#!/usr/bin/python2
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==9.0.1','console_scripts','pip'
__requires__ = 'pip==9.0.1' import sys from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('pip==9.0.1', 'console_scripts', 'pip')()
    )

3. Now save and check:

lerner@lerner:~/$ pip -V

pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

Done.

  • You can use alias pip = 'pip2.7'Put this in your .bashrc file(If you're using bash,if zsh it should be .zshrc).

    By the way,you should know that sudo command change current user,default root.So if you have to change user to root,maybe you should put it in /root/.bashrc

  • Or you can make a link

    ln -s /usr/local/bin/pip2.7 /usr/local/bin/pip

Also you can try to use virtualenv,it's the best choice for multiple versions in my opinion.
