Test suite fails (cannot import name pystone) #5

Closed nidico closed 11 years ago

nidico commented 11 years ago

Building zope.testbrowser on my Fedora 18 machine with python-2.7.3 and virtualenv-1.9.1 from PyPI fails, using the enclosed buildout. This came up in #4 originally. This is the full stack trace:

I'm not having this problem using the same setup on a Debian Squeeze VM.

Can you run bin/test --pdb, and then at the pdb prompt do

(pdb) !import test
(pdb) p test.__file__

And also show us the contents of the buildout-generated bin/test script?

nidico commented 11 years ago

Sure:

Ok, this looks like an issue with Fedora's Python packaging (they do not ship the test.pystone module in their main Python package), and nothing to do with zope.testbrowser.

yum install python-test and the tests should pass.

nidico commented 11 years ago

Confirmed! Thanks for looking into this!

ImportError: cannot import name pystone -> solution is yum install python-test. Thank you, it works~~

ramadivyasri commented 8 years ago

I'm facing the same issue: File "/usr/lib/python2.7/site-packages/dpkt/decorators.py", line 4, in from test import pystone ImportError: cannot import name pystone

But, yum install python-test did not resolve the issue. What else can be done?
