multiple versions of python, how to install python package on a specific version?

Question

I have a remote machine with Python 2.6 installed. I then installed python 2.7 using these instructions python install. I then set up an alias so scripts will use 2.7 in future.

How do I install numpy to python 2.7.

pip2.7 install numpy, if you also installed pip. Otherwise using the correct alias/python when installing from source, you can do python setup.py install and it will be installed in <prefix>/lib/python2.7/site-packages. — user707650

Python keeps track of its major versions by using lib/pythonx.y directories for packages. If you also installed python itself with make altinstall, it won't even overwrite the current default python command (can be safer for your system), and you'll only get things like python2.7 as commands. — user707650

For more control over what's installed for what, use a virtualenv, then you can specify the Python interpreter version to use and install specific tools for specific tasks. — jonrsharpe

What is the alias you used? Not a link I suppose? Because the latter could mess around with system scripts (depending on your OS); although Python 2.7 should be compatible with 2.6 scripts. — user707650
