I want to install a library on my debian machine and it requires a python version above 2.6.6-7. The machine had installed the version 2.5.2-3, so I installed python 2.7.

When I run python -V, the output is "Python 2.7", but when I try to install the library, it outputs "Version of python on system is 2.5.2-3.". How can I solve this?

The library I'm using is paramiko, in order to use ssh communication. If, instead of solving the above, you could suggest another library which works with python 2.5, it would be apreciated as well.

  • How did you install python 2.7? I suspect you installed it to /usr/local which is why your library cannot find it.

Assuming you install from pypi you have to make sure that your easy-install or pip uses the right version of Python, e.g. by using:

pip-2.7 install paramiko

If you install from an extracted source file, I recommend you explicitly use python2.7 or use the full path to the python2.7 executable.

sudo python2.7 setup.py install
