Installation Error--pkg_resources.DistributionNotFound: TurboGears==0.9a6

[Matt Culbreth]

Hello Folks,

I'm trying to install TurboGears 1.0b on my MacBookPro. I've
previously done this and it works, but I'm problems this time.

I follow the base instructions (download tgsetup.py, run it) and it
seems to work. However when I type "tg-admin" I get the following
stack trace:

Traceback (most recent call last):
File "/usr/local/bin/tg-admin", line 5, in ?

line 483, in resolve
raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: TurboGears==0.9a6

Any ideas here? I've wiped my system a few times of setuptools and TG
but to no avail. It's got to be something easy...

In
...../lib/python2.4/site-packages/
'am assuming you:
. deleted all TG related .egg files and folders
. deleted all TG related entries in easy-install.pth
or removed it all together.

Have a feeling its using the TG 0.9a6 entry in the .pth file
or some such.

See if running usr/bin/tg-admin gives the same result. If it works, copy /usr/bin/tg-admin to /usr/local/bin/tg-admin and you should be all set.

[Matt Culbreth]

That seems to have done. I whacked out everything I could find that TG
might use, did it again, added
/Library/Frameworks/Python.framework/Versions/2.4/bin to my PATH and it
worked.

Thanks for the help!

I'm having a similar problem running tg-admin, but the error is
regarding the PIL package. I've followed the suggestion to copy
tg-admin to /usr/local/bin/, with no effect.

What is turbogears' tg-admin (or setuptools), asking for with this
error message?

$ /usr/bin/tg-admin --help

The individual components are working well enough, and turbogears has
generally worked with this configuration in the past. I use Gentoo
Linux' system package for PIL and a few other packages, setuptools for
everything else. Some environment info:
