It seems like the issue might be that I want it to install the pipenv with python 3.5, but it's using python 3.6? I have both installed and in PATH. I'm not sure why an installer would be timing out.

I had previously installed a pipenv with 3.6 and removed it with some difficulty (I had to manually delete the virutalenv), so that may be part of the cause.

EDIT:

On a second attempt, it just hangs forever at Using C:\Users\danie01\AppData\Local\Programs\Python\Python35\python.exe (3.5.0) to create virtualenv...

Answer 1

pipenv ran a subprocess, and that process took longer than the default 15 minutes, then expect.py was told to wait for a newline but it hit the timeout and here you are. First step is to increasing the TIMEOUT value in:

PIPENV_TIMEOUT 

https://pipenv.readthedocs.io/en/latest/advanced/#configuration-with-environment-variables

PIPENV_INSTALL_TIMEOUT
    Max number of seconds to wait for package installation.
    Defaults to 900 (15 minutes), a very long arbitrary time.

If it's hanging forever, then the question becomes: What was pipenv told to do that results in a block? Use the --verbose flag to tell pipenv to tell you what it's doing that results in a hang.

#try
export PIPENV_INSTALL_TIMEOUT=9000
