mypy-pycharm: MacOS: Error while checking Mypy path

Step 1: Are you in the right place?

I have verified there are no duplicate active or recent bugs, questions, or requests
I have verified that I am using the latest version of the plugin.

Step 2: Describe your environment

Plugin version: 0.10.2
PyCharm/IDEA version: 2018.3.4 Build #PY-183.5429.31
Mypy version: 0.620

Step 3: Describe the problem:

Steps to reproduce:

Install mypy using brew install mypy
Restart pycharm

Observed Results:

Pycharm indicates a fatal error “Error while checking Mypy path”

Expected Results:

Pycharm should load without complaining

Relevant Code:

I think the plugin is throwing an error when executing the /usr/local/bin/mypy file as installed by brew but I can’t see why. This file contains:

#!/bin/bash
PYTHONPATH="/usr/local/Cellar/mypy/0.620/libexec/lib/python3.7/site-packages:/usr/local/Cellar/mypy/0.620/libexec/vendor/lib/python3.7/site-packages" exec "/usr/local/Cellar/mypy/0.620/libexec/bin/mypy" "$@"

I see a similar problem on OSX using the path of mypy inside my project’s venv, using Intellij with the python plugin

I had this issue with pyenv with both python 2.7 and python 3.7 installed. Once I was able to resolve down to a single version I was able to take the output of pyenv which mypy and paste it into the path to mypy executable (preferences/mypy) and everything worked fine.

@leinardi It looks like it’s not a regression. It’s not working for me in all 3 versions. I can only get it to work if I install mypy in the project’s virtualenv and use that in the settings.

Steps to reproduce:

brew install mypy
Create new project in pycharm with default virtualenv.
Go to mypy settings
Set ‘Path to mypy executable’ to /usr/local/bin/mypy
Click ‘Test’

I had the same error on Windows 10 Pycharm community 2018.3.5

FYI I am getting the same error on Ubuntu Linux 18.04, Pycharm 2018-03-05, Mypy 0.67, Mypy plugin version 0.10.2. Seems like the path is not getting detected.
