Did you ever find the fix for this? I just ran into the same error

Denis Angell · Answer 2 · Sat Jan 13 2018 04:21:22 GMT+0800 (China Standard Time)

I'd like to use this, however, if its not going to work, I'll just go back to truffle... lol

bonedaddy · Answer 3 · Sat Jan 13 2018 04:48:23 GMT+0800 (China Standard Time)

No unfortunately I did not. Ive also run into breaking bugs with this and web3py which is a shame all the Python tools for Ethereum are quite honestly garbage

Denis Angell · Answer 4 · Sun Jan 14 2018 00:40:40 GMT+0800 (China Standard Time)

And yeah, I have too. What problems are you having with web3.py? I’ve fixed most of mine so far, so maybe I can help you?

Denis Angell · Answer 5 · Sun Jan 14 2018 00:41:51 GMT+0800 (China Standard Time)

Also, when you copy the json file, make sure you read the notes, as the json has to be at the root project level.

@harpangell7 I was able to get the tests running by following the instructions in issue #414 However I get the following error now

Did you get this fixed?

Walker · Answer 8 · Mon Jan 29 2018 08:57:46 GMT+0800 (China Standard Time)

Is there a fix for this?

bonedaddy · Answer 9 · Sat Feb 10 2018 15:02:48 GMT+0800 (China Standard Time)

No never found a fix

Noel Maersk · Answer 10 · Wed Feb 14 2018 19:09:28 GMT+0800 (China Standard Time)

Likely duplicate of #414 (EDIT: ah, has been mentioned).

Mandar Vaze · Answer 11 · Fri Feb 23 2018 15:58:48 GMT+0800 (China Standard Time)

I ran across the error reported at the beginning of this issue i.e. FileNotFoundError: No populus project found for testing in ..
After applying the "fix" from #414 - the error went away.
I did not encounter any other error, and the tests passed.

Populus Version: 2.2.0
OS: osx

Problem:
FileNotFoundError: No populus project found for testing in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/populus/plugin.py:60

Solution:
when we run $ populus init command it will Wrote default populus configuration file at this location /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/populus/assets/defaults.v8.config.json

copy defaults.v8.config.json file and paste it on your project and rename defaults.v8.config.json to project.json file. This solution solved the issue for me

Closing since I don't use this library anymore
