Adding python to /usr/bin/env python variable

Question

The #!/usr/bin/env python hashbang isn't working on my Ubuntu install.

I tried the following:

root@x# python=/usr/bin/python
root@x# PATH=$PATH:/usr/bin/python

Solution

If you're using bash (which you probably are in a default Ubuntu install) you need to use export to set an environment variable on the command line.

export PATH=$PATH:/usr/bin

See @chaos's comment as well. Make sure env is showing your proper $PATH, eg:

bash-3.2$ env | grep PATH
PATH=/usr/bin:/bin:/usr/sbin:/sbin
bash-3.2$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin

Can you please post the output of env | grep PATH and env python --version and which python?

It's not clear exactly what's not working.
