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.

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?

Yep, happening with the latest master.

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

@greysteil

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

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.)

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

Fixed on master. 🎉

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.

/Users/greysteil/code/pipenv/pipenv/_compat.py:108: ResourceWarning: Implicitly cleaning up <TemporaryDirectory '/var/folders/kv/y02nj9zd5ss16sn505tk6g_40000gn/T/pipenv-j9WSGO-requirements'>
  warnings.warn(warn_message, ResourceWarning)

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.
