由于超时，pipenv安装失败

似乎问题可能是我希望它用python 3.5安装pipenv，但是它使用python 3.6？我已安装和PATH。我不确定为什么安装程序会超时。

我之前安装了3.6的pipenv并且有一些困难将其删除（我不得不手动删除virutalenv），所以这可能是原因的一部分。

编辑：

在第二次尝试，它只是永远挂在Using C:\Users\danie01\AppData\Local\Programs\Python\Python35\python.exe (3.5.0) to create virtualenv...

Answer 1

在Windows上，关闭Windows Defender对我有用。我没有经历任何超时，安装速度更快。

Answer 2

pipenv运行了一个子进程，并且该进程花费的时间超过了默认的15分钟，然后expect.py被告知要等待换行符，但是它达到了超时，就在这里。第一步是增加TIMEOUT值：

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.

如果它永远悬空，那么问题就变成了：pipenv被告知要做什么导致阻塞？使用--verbose标志告诉pipenv告诉你它正在做什么导致挂起。

#try
pipenv install --timeout 9000

Answer 3

你能删除你的旧virtualenv C:\Users\danie01\.virtualenvs吗？

检查Pipfile中的python版本

[requires]
python_version = "3.5"

在你的项目再次创建你的virtualenv之后

cd C:\Users\danie01\fox\test\robotframework
pipenv install
