如何解决?
推荐答案
看来你不使用 virtualenv 并且你的 pythons/paths 可能搞砸了.我在 Ubuntu 14.04 上遇到了与 python-2.7 和 -3.4 类似的问题.我试过
It seems like you don't use virtualenv and your pythons/paths are probably messed up.
I faced with similar problem with python-2.7 and -3.4 on Ubuntu 14.04. I tried
sudo python -m pip install --upgrade --force-reinstall pip
对于 2.7，它有帮助.然后我通过 easy_install3 为 python-3.4 重新安装了 pip.
for 2.7 and it helped. Then I reinstalled pip for python-3.4 via easy_install3.
