fixture 'chain' not found when running tests on fresh instance about populus HOT 5 CLOSED

@rbval I was getting the same error. My problem was that pytest was not installed in the same virtualenv. what does which py.test say for you?

Populus Version: -e git+https://github.com/ethereum/populus#egg=populus (fresh install throws the force_text error

If you install from current master then this issue should be resolved.

@voith
which py.test gives me /usr/local/bin/py.test

Going for pip install py.test in the virtualenv throws the following error: ValueError: please use 'pytest' pypi package instead of 'py.test'

However if I do: pip install pytest it gives Requirement already satisfied to everything. How did you solve this in the virtualenv @voith ?

/usr/local/bin/py.test

You're facing the same problem that I was facing. It tells you that pytest is being picked from your global path.

pip install py.test

the . in pytest is not longer needed. pip install pytest will do.

Also, I had to deactivate and re-active the virtualenv to make sure that it is picking pytest from the correct path (virtualenv).

Closing this as it is not a bug in populus, but feel free to continue the discussion.

Alright, the activate + deactivate seemed to work, weird. How would that be handle in a Dockerfile for example?
