6 years ago Oh, @nicholasbishop sorry for missing this earlier, you should not be running pipenv install from inside pipenv shell. You really shouldn't be doing much of anything from inside a pipenv shell. This is a convenience function for people who really need subshells. Firstly, anything that absolutely needs to run inside the virtualenv should run with pipenv run <script>. Secondly, you don't actually have pipenv installed in your virtualenv, so it can't possibly resolve accurately when you are in that context. Pipenv is designed to manage the environment for you, along with your dependencies. It can only do this from outside the environment. The minute you enter a subshell and start using pip or pipenv you will break things.
To summarize, never ever use pipenv inside its own shell -- it isn't designed for this and won't work

6 years ago Oh, interesting. Perhaps the documentation should make that clearer? It's not obvious what the shell command is for from the help:
shell Spawns a shell within the virtualenv.

_=/usr/bin/envHuh, that is very odd @nicholasbishop -- so it's not finding any match for pyqt5 at all when you run pipenv install pyqt5? Do you have internet connectivity? I can see SHLVL=2 -- is this inside a subshell like inside emacs or in a chroot? I'm concerned that your install was pulling from the local wheel cache in the first place which would explain why you can't resolve dependencies which requires the ability to query PyPI.

6 years ago @nicholasbishop it does work fine, but I only tried with pyenv and python 2,7.14. I installed 2.7.13 and promptly had this issue, however I accidentally forgot to specify which python version to make my virtualenv with when I did this which inadvertently uncovered the actual problem.
I had called pyenv local 2.7.13 followed by pip install pipenv which mean I was using a python 2.7.13 build of pipenv to resolve dependencies. This provided an additional hint, because like you, I can no longer install pyqt5 on python 2.7.13 at all. So I dug a bit deeper and checked PyPI's json-formatted pyqt5 package listing and discovered that pyqt5 only lists wheels for licensing reasons and those wheels only support python 3.5 and higher.
Digging even deeper I found that, according to the current pyqt5 documentation, this is an intended behavior and you can only use python 3 to install pyqt5 from pypi now.
Like you, I was able to get this to install on python 2.7 earlier today, but unlike you I was using a python 3.6 install of pipenv which handles locking, which explains why I had success where you didn't. I have to assume this change was made very recently since it was installing successfully from pypi within the last few hours and now it isn't

6 years ago To close the loop on this in case anyone else runs into it, here's how I ended up resolving the problem on my system:
# Clean out the old installation
rm -r ~/.local/venvs
rm ~/.local/bin/pew
rm ~/.local/bin/pipenv
rm ~/.local/bin/pipsi
# Slightly different method of installing pipsi as suggested here: https://github.com/mitsuhiko/pipsi/issues/89
curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python3 - --src 'git+https://github.com/mitsuhiko/pipsi.git#egg=pipsi' --ignore-existing
pipsi install pew
pipsi install pipenvNow when I install pyqt5 everything looks fine:
