pipenv - Installed via Homebrew - errors on matplotlib installation

Pipenv (installed via Homebrew) crashes after installing matplotlib. To verify that it wasn’t something in my environment, I have replicated it on a clean-build VM of macOS High Sierra 10.13.1 (17B1003). Note that matplotlib installs fine in this environment manually (using python -m venv and pip install matplotlib), and it appears that pipenv successfully installs it into the virtual environment created by pipenv. However, pipenv errors-out after the installation and doesn’t produce a lock file.

Environment:

• macOS High Sierra 10.13.1
• Python Interpreters:
  • python Python 2.7.10 (system)
  • python2 Python 2.7.14 (installed via pyenv)
  • python3 Python 3.6.3 (installed via pyenv)
• pipenv, version 8.3.2 (installed via homebrew)

Steps to Reproduce:

$ mkdir -p ~/dev/projects/pipenv-matplotlib
$ cd ~/dev/projects/pipenv-matplotlib
$ pipenv install --three --verbose matplotlib

Output: (verbose output attached)

@cmlccie Saw this issue, I was facing the same with installing jupyter and reading @vphilippon 's comment, the workaround that worked for me:

1. Uninstall homebrew based pipenv
2. brew install python3 (If you don’t have already)
3. python3 -m pip install pipenv

Now try installing matplotlib. Should work until the PR is merged in homebrew.
