似乎问题可能是我希望它使用 python 3.5 安装 pipenv，但它使用的是 python 3.6？我已经安装并在 PATH 中。我不确定为什么安装程序会超时。

我之前安装了一个 3.6 的 pipenv，但遇到了一些困难（我不得不手动删除 virutalenv），所以这可能是部分原因。

编辑：

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

标签： python installation virtualenv pipenv

【解决方案1】：

你能删除你旧的 virtualenv C:\Users\danie01\.virtualenvs

检查Pipfile中python的版本

[requires]
python_version = "3.5"

转到您的项目后再次创建您的虚拟环境

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

【解决方案2】：

在 Windows 上，关闭 Windows Defender 对我有用。我没有遇到超时，安装速度也快得多。

【讨论】：

对于 Windows 10，我搜索并打开“Windows Defender”，单击“防火墙和网络保护”，公共网络连接处于活动状态，所以我单击“公共网络”，然后打开“Windows Defender 防火墙” " 关闭。

【解决方案3】：

pipenv 运行了一个子进程，该进程花费的时间超过了默认的 15 分钟，然后expect.py 被告知等待换行符，但它达到了超时，你就在这里。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.

如果它永远挂起，那么问题就变成了：告诉 pipenv 做什么会导致阻塞？使用 --verbose 标志告诉 pipenv 告诉你它正在做什么导致挂起。

#try
export PIPENV_INSTALL_TIMEOUT=9000

【讨论】：

【解决方案4】：

这有助于我在 Raspbian 上安装 Raspberry Pi 3B+。

# if actual install steps fail (installing X/X .. )
# default 900 seconds, 15 minutes, long time
export PIPENV_INSTALL_TIMEOUT=9999

# if creation of virtual env fails (very first step, first time)
# default 120 seconds, 2 minutes, not so long
export PIPENV_TIMEOUT=999

pipenv install requests

有关这两个值的完整定义，请参阅 https://pipenv.pypa.io/en/latest/advanced/#configuration-with-environment-variables。

【讨论】：

将 PIPENV_TIMEOUT 和 PIPENV_INSTALL_TIMEOUT 都设置为 9999 对我有用 (pipenv.readthedocs.io/en/latest/advanced/…)。

【解决方案5】：

根据您运行pipenv install 命令的位置，将环境变量PIP_NO_CACHE_DIR 设置为off。就我而言，我在我的 Dockerfile 中通过在 ENV PIP_NO_CACHE_DIR=false 之前添加一行 RUN pipenv install 来设置它

【解决方案6】：

我使用的是url = "https://pypi.tuna.tsinghua.edu.cn/simple"，并且对于安装的每个依赖项，我都会遇到超时错误。当我将网址更改为简单的工作时。

[[source]]
name = "pypi"
url = "https://pypi.python.org/simple"
verify_ssl = true

【解决方案7】：

尝试做pipenv --rm - 删除虚拟环境

然后pipenv shell - 这将再次启动虚拟环境

然后再次pipenv install

为我工作
