Install a module using pip for specific python version

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
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. Update: In the modern (2020s) world, python -m pip is the right way to do this, where python can be replaced with whichever interpreter you choose.
