python - Change default Ubuntu pip to pip2.7

Question

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)
