FileNotFoundError from 'pipenv install requests' when pwd is a symlink

I cd to my project in this directory:

$ pwd
/home/jhartley/docs/code/unfinished/gloopy

But that’s actually using a symlink, ~/docs -> ~/Dropbox/jon-data. The actual directory name is:

$ pwd -P # resolves symlinks to give actual directory name
/home/jhartley/Dropbox/jon-data/code/unfinished/gloopy

Note ‘Dropbox’ has a capital ‘D’.

I just installed pipenv for first time ever. No Pipfile is present. $ pipenv install requests Gives the traceback below, which includes “Dropbox” spelled incorrectly, with a lower case “d”.

pipenv, version 7.6.3. Ubuntu 17.04. Pythons 2.7, 3.5 and 3.6 are installed, but ‘python’ is python2.7. Using --three doesn’t help.

I’m happy to do any more diagnostics if it helps.

great news! yeah we fixed that bug recently 😃

FWIW, yesterday my Pipfile had the erroneously lower-cased path in it (I don’t have a copy of that). I was deleting Pipfile* (and rmvirtualenv) and regenerated it like that a number of times. But today (in a new login) it’s looking fine to me:

$ cat Pipfile
[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages]

"0269f63" = {path = "/home/jhartley/Dropbox/jon-data/code/unfinished/gloopy", editable = true}
numpy = "==1.13.0rc2"
pyopengl = "==3.1.0"
"pyopengl-accelerate" = "==3.1.0"
pyglet = "==1.2.4"
requests = "*"
