pipenv update created too many subprocess until crash

[yixblog]

I installed new python3.7.4 amd64 into Windows 10 Home OS

And installed pipenv by pip install pipenv

But when I was initializing my python projects with pipenv update command (pipenv install also tried). The command screen shows creating virtualenv and keeping creating huge number of sub process until the system got out of memory or just crashed.

As this image shows, the number of subprocess is increasing very fast until took down all CPU and Memory resources but did nothing. I cannot even init a new project. I don't know if there were any mistake.

And the previous mistake in the image is caused by command: pipenv --py

The problem is probably related to this virtualenv issue. For the moment the solution is to downgrade to Python 3.7.3, as it happens only with 3.7.4.

Pin this issue for any newcomers who encountered this problem.

The fix should be released via https://pypi.org/project/virtualenv/16.6.2/, upgrade virtualenv to >=16.6.2 should fix this problem.
