`TypeError: can only concatenate str (not "type") to str` instead of actual error

[aidin36]

Issue description

In some cases, pipenv outputs TypeError: can only concatenate str (not "type") to str instead of the actual error (or after printing out the actual error). It faces an error while handling the actual error.

Steps to replicate

Set WORKON_HOME to somewhere that current user doesn't have permission for writing to. Example:

WORKON_HOME=/opt/ pipenv install

---

I encountered the issue on the latest source code from the Github.

I get this error by starting pipenv shell. There actually two errors I found:

ModuleNotFoundError: No module named 'pkgutil'

and

TypeError: can only concatenate str (not "type") to str

directly after running pipenv shell

C:\Users\Me\git\pdf-organize-automation>pipenv shell
Creating a virtualenv for this project…
Pipfile: C:\Users\Me\git\pdf-organize-automation\Pipfile
Using c:\users\me\appdata\local\programs\python\python37\python.exe (3.7.0) to create virtualenv…

I am not sure, what I can do

The issue is a problem with a dependency in pipenv. You can fix this by installing from the working update until the release is out: pip install git+https://github.com/pypa/pipenv.git@update-vendor#egg=pipenv

Hi @techalchemy Could you look at this issue again? I still get this issue when I installed latest master branch with commit e3ee806. Thanks.

TypeError: cannot concatenate 'str' and 'type' objects

Yikes. Any chance you can print or log the type? I’m guessing it’s an EOF still?

@techalchemy Hi, I found it is TIMEOUT. I made a PR #3159 for that.
