macports python_select command not found

问题

I'm using MacPorts and had installed python_select to switch between 2.6 and 2.7. But for some reason I'm now getting a "command not found" error when running:

sudo python_select python26 

Possibly an issue with $PATH? Not sure where to look for it.

回答1:

python_select isn't a command, it is a capability added to port select.

To use it:

1. List the available pythons to select from:
   

   port select --list python
   

2. to choose a specific port (eg python26):
   

   port select python python26
   

回答2:

See answer to subsequent reframing of question:

macports didn't place python_select in /opt/local/bin

回答3:

Eh, on my Lion, I use:-

$ sudo port select --list python

to see available python versions, and:-

$ sudo port select python python26

No _ necessary for me! YMMV
