我不知道原因，但函数mkvirtualenv以下列错误结束：

LEP:~ lep$ mkvirtualenv myenvironment

之前正在工作，现在我收到了这个错误。有人可以帮助我吗？

Answer 1

看起来你正在使用Anaconda Python。您should be使用Conda执行此操作而不是virtenv。

尝试：

LEP:~ lep$ conda create --name myenvironment

Answer 2

尝试降级到python版本2.7.9

conda install python=2.7.9

感谢the GitHub conda issues section
