Dealing with multiple Python versions and PIP?

Question

Is there any way to make pip play well with multiple versions of Python? For example, I want to use pip to explicitly install things to either my s

Other answers show how to use pip with both 2.X and 3.X Python, but does not show how to handle the case of multiple Python distributions (eg. original Python and Anaconda Python).

I have a total of 3 Python versions: original Python 2.7 and Python 3.5 and Anaconda Python 3.5.

Here is how I install a package into:

1. Original Python 3.5:

   /usr/bin/python3 -m pip install python-daemon
   

2. Original Python 2.7:

   /usr/bin/python -m pip install python-daemon
   

3. Anaconda Python 3.5:

   python3 -m pip install python-daemon
   

   or

   pip3 install python-daemon
   

   Simpler, as Anaconda overrides original Python binaries in user environment.

   Of course, installing in anaconda should be done with conda command, this is just an example.

Also, make sure that pip is installed for that specific python.You might need to manually install pip. This works in Ubuntu 16.04:

sudo apt-get install python-pip 

or

sudo apt-get install python3-pip
