[vphilippon]

That's fixed by #833, which is in master but not yet released.

[goern]

cool, I can wait a day for the release :)

[nateprewitt]

Didn't realize we were waiting on a release from us. I'll try to get something out today.

@vphilippon continuing discussion from #871, pipenv lock --verbose --clear gave me:

Updated Pipfile.lock (e011c0)!

Now it works fine, thanks. So seems like updating to fixed version won't work until you clear cache.

[nateprewitt]

8.2.7 was just released to PyPI so this should be resolved and available.

[goern]

Affirmative. Thanks!

[vphilippon]

@nateprewitt Just in case you skipped it, I noticed there's no tag/release on github for 8.2.7 (which confused me at first).
It's still on Pypi allright, it just surprised me.

[nateprewitt]

Thanks for catching that @vphilippon. Looks like our release build hiccuped on that step and I didn't notice. Tag is pushed now.

[AlJohri]

@nateprewitt I _think_ I'm still running into this one on 8.2.7 as described here: https://github.com/kennethreitz/pipenv/issues/712#issuecomment-338518518

[AlJohri]

I take it back - seems to have resolved it self after explicitly running pipenv install matplotlib. I was previously just running pipenv install with matplotlib listed in the Pipfile. ¯_(ツ)_/¯ works now!
