pip 不获取任何链接

Question

我刚刚从源代码安装了 Python 3.4，现在想用 pip 来下载一些包。但是每次我运行它，比如说：

pip install -v django

我都会遇到以下错误（和 /root/.pip/pip.log 中的输出一样）：

我的网络连接没问题（我可以正常更新系统，ping 一下谷歌也没问题……），而且 https://pypi.python.org/simple/Django/ 这个地址肯定是存在的（我现在就能看到）。而且，我可以使用 pip list、pip search，当我手动用 wget 下载包后，再用

python setup.py install

也能正常工作，甚至还能下载依赖包。我没有使用代理。这是在 Raspberry Pi 上运行的，系统是 Arch Linux。我的网络连接是静态的。Python 运行得很好，pip 也已经安装（在 3.4 中是默认的）。

谢谢

我重新安装了我的虚拟环境，这次是用本地的Python版本，没有使用符号链接，现在一切都正常了。谢谢大家！
