pkg_resources.DistributionNotFound when running pcreate

[Michael]

after creating a new virtualenv and installing pyramid via easy_install, I simply call `pcreate` and I get this error:

 

pkg_resources.DistributionNotFound: pyramid==1.5a2

any ideas why? Python 2.7.3 Log follows:

Look closely here: you're running /usr/local/bin/pcreate instead of
/Users/michael/src/py/test_env/bin/pcreate.

Why? I'd've assumed that sourcing the activate script would put
/Users/michael/src/py/test_env/bin/ in front of your $PATH.

Can you try 'echo $PATH'?

Can you try 'hash pcreate' to see if bash had the full location of it
cached from before (but I always thought changing $PATH invalidates the
bash command hash table).

Or just quit relying on activate and use 'bin/pcreate' (or whatever) to
ensure you are getting the one you want.

Turns-out the problem was that I had an old version of pcreate in the dirs where home-brew installs python .. on both machines.

Thanks for the tips.
