Question

我安装了python 3.5.2。我也安装了pip 9.0.1。当我输入命令python或pip --version时，会显示版本号。但是当我尝试使用命令pip install Django安装django时，在一定百分比之后，它会停止下载并在命令提示符处出现以下错误。我试图设置路径，但仍然出现错误。

Exception:

Answer 1

回溯告诉您的是，分配给一个读取操作的最大时间已用完，因此操作已中止。这可能是由于连接速度低，在这种情况下，快速修复可能会增加安装包的超时时间。试试这个：

pip --default-timeout=500 install django

其中500是以秒为单位的时间量。随意增加/减少它。希望它有所帮助。

Answer 2

您应该使用virtualenv

创建虚拟环境。然后安装django：pip install django，而不是Django
