Pipenv: lock command fail with "TypeError: 'NoneType' object has no attribute '__getitem__'"

[BrunoBerisso]

Hi,

I'm just installed pipenv today and I'm also new to python so, this may be a dumb error from my side.

Every time I'm trying to create a Pipfile.lock with pipenv lock it crashes. This is the full output:

➜  pipenvTest pipenv --version

This was also happening with the 3.2.4 version.
Thanks in advance

Thanks for opening this @BrunoBerisso, this is something that we're aware of. This is tangential to #90, in that we're expecting a certain file format syntax. Twisted which is a dependency of Scrapy is providing their packages using bzip2 for compression rather than gzip like most of the other packages on PyPI.

This should be resolved when #90 is closed. I'm going to close this in favor of that ticket.

Hey I just installed pipenv and I get this problem:

❯ pipenv install --three --verbose
Warning: PYENV_ROOT is not set. New python paths will probably not be exported properly after installation.

@eleijonmarck it looks like you have pyenv installed but as the warning says you don’t have PYENV_ROOT set. You need to set that environment variable. Based on the fact you have pyenv installed but pip and pipenv are still coming from /usr/local/bin I’m guessing you don’t have the pyenv shims directory on your path either. You will need to add that to your path to use pyenv.

@techalchemy Thanks for the quick answer. It was actually a encoding problem in the background.
Had to add

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

To my shell and then it worked

[techalchemy]

@eleijonmarck awesome and thanks for the update! I’m guessing you had the environment var for pyenv set then? If we don’t have a warning about this still I’ll see if we can get one since this will probably continue causing problems
