使用pip时"SSLError:读取操作超时"

Question

每当我尝试安装一些东西时 pip我都会收到以下错误:

Downloading/unpacking Django>=1.5.1,<1.6 (from -r requirements.txt (line 1))

这曾经不时发生在我身上,但现在我无法安装任何东西.我尝试添加--timeout=600,但它在相同的时间内失败(达到8.0M后几秒钟).
关于如何解决这个问题的任何想法？

Answer 1

尝试(注意--default):

pip --default-timeout=100 install django

如果它仍然不起作用,你可以手动下载django1.5.4和:

https://docs.djangoproject.com/en/dev/topics/install/#installing-an-official-release-manually

类似的问题:

点击搜索django产生超时错误, 在MacOSX Lion上点击安装django超时

Answer 2

这通常是因为互联网连接不畅,即; 安装过程中丢失互联网连接重做命令,它应该工作正常.
