On Windows, need to run buildout multiple times (it intermittently crashes) before all dependencies are downloaded

[KayJay89]

Hi all,

Been struggling for couple days to get this working but I am failing each time and running out of answers. I can't seem to get the buildout to run properly:

(try) C:\gtfs\gtfsdb>buildout install prod
Develop: 'C:\gtfs\gtfsdb\.'
c:\gtfs\try\lib\site-packages\setuptools\dist.py:352: UserWarning: Normalizing '0.1.6dev' to '0.1.6.dev0'

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

After tinkering a bit more I found a solution that worked for me. Bear in mind I'm using a virtual env. I followed every step however before running buildout, I ran setup.py.

Is that normal behaviour or am I still doing something wrong in one of the steps?

Edit 2: I also found out that when you run "buildout install prod postgresql" 3 times. The third time, the assertionerror is gone.. I am absolutely clueless what is going wrong here honestly.

i also am having this problem installing on Windows. I ran "buildout install prod postgresql" like @KayJay89 and it seems to have worked now...

This shouldn't be the case, and it wasn't the case in years past. That said, I've recently seen similar issues on Windows. Ever since upgrading setup tools and buildout (needed newer versions for recent pypi https fixes), I've seen that buildout intermittently dies on loading dependencies. My current work-around is to just re-run buildout, and eventually get a working buildout. Not sure these problems are due to something in gtfsdb's setup.py or buildout.cfg.

Going to close this issue in favor of #67 (move to puppet).
