pipenv install python-Levenshtein fail

I tried to install python-Levenshtein with pipenv and I had the following error:

In the PipFile I had:

python-levenshtein = "*"

By adding an uppercase, it finally worked:

python-Levenshtein = "*"

[systemcatch]

The name of the package on pypi is python-Levenshtein, so it will always need to be specified as that in the pipfile.

The issue is when I run the command pipenv install python-Levenshtein this error occurs because the name in the PipFile automatically became python-levenshtein. I had to change it manually and run pipenv install again. Le jeu. 6 févr. 2020 à 19:30, Chris <notifications@github.com> a écrit :

@morganednl that sounds like an issue with pipenv not respecting uppercase letters in the package name, seems like this has occurred before pypa/pipenv#1314
