Error: no installed version

[Weless]

I have some different kind of python installed before p, how can p list my version?

[ahnbizcad]

Does p ls not suit your needs?

you could list your normal linux packages like so:
dpkg --list | grep python

when I run "p" , it only show "Error:no installed version",how can I fix this problem?

Me too. It just show "Error:no installed version". seems like it can't detect any python version installed before it
