使用比Linux服务器上安装的Python版本新的Python

Question

I have an account on a Linux server which currently has Python2.4 installed on it so by default running the command which python returns /usr/bin/python

I have installed Python2.7 in my account home directory @ /path/to/myaccount and have set and sourced the path in my .bash_profile file as

PYTHONPATH=/path/to/myaccount/bin/python
export PATH=$PYTHONPATH:$PATH

However I am still getting Python2.4 as my default Python.

Answer 1

PYTHONPATH tells Python where to look for modules and packages ( .py files etc)

You need to make sure your shell is looking in the right place for the Python binary

export PATH=/path/to/myaccount/bin:$PATH
