Version resolution sometimes fails when no previous virtual env exists #2435

greysteil · 2018-06-26T23:13:19Z

Weird one, but I can reproduce the below consistently. I think it's due to resolution relying on the existing state of the virtualenv, but I could be missing something.

Note: This bug is new in 2018.6.25 - I don't get it in 2018.5.18.

I only get the above error when I run the command for the first time in a fresh virtual env. Running a second time I get successful resolution.

Steps to replicate

rm -rf ~/.local/share/virtualenvs/ # Remove virtual envs
pyenv exec pipenv lock             # Generate lockfile with Pipfile foud in environment details above

Note, I have Python 3.6.5 (default) and Python 2.7.15 installed via pyenv.

The text was updated successfully, but these errors were encountered:

techalchemy · 2018-06-27T00:13:32Z

Huh, I've been wondering about that bug. I am not sure what exactly is the cause but the fact that it only happens in fresh environments is new information for me. does this happen with master also?

greysteil · 2018-06-27T00:28:46Z

Yep, happening with the latest master.

Let me see if I can get the commit that introduced it for you...

greysteil · 2018-06-27T00:39:43Z

OK, so it was definitely introduced by #2267. Resolution works fine on d55e400 but I get the same error as above on e135f7c.

greysteil · 2018-06-27T00:47:40Z

Within that PR, it's introduced by either bba2f38 or 7abc2fd. (I get a different error for 7abc2fd which may be masking it, but definitely get it with bba2f38 checked out.)

techalchemy · 2018-06-28T01:22:41Z

Yeah that makes perfect sense, try against master now that I updated requirementslib, otherwise try against #2453 maybe

greysteil · 2018-06-28T03:14:03Z

Fixed on master. 🎉

greysteil · 2018-06-28T20:13:17Z

Argh, @techalchemy, you're going to hate me but I jumped the gun on this. It's still happening, although possibly less often - I now can't always reproduce it just by removing the virtualenv.

Here's my terminal output from running pyenv exec pipenv lock -v a few times, using master. Most of the time I get the error, but sometimes resolution succeeds.

Some observations:

If the error happens, it always happens during the Finding secondary dependencies: step
The error can happen in any round of resolution
Within the output of Finding secondary dependencies:, it's not always the same dependency that's just been output before the error occurs

I'm at a bit of a loss on where to dig next.
