Incompatible between conda and virtualenv

[nengwenzhao]

I find that if your computer installed Anoconda, the build process will report errors. The solution is delete the Anoconda folder, when the environment build is finished, then restore the Anoconda folder.

This could be a problem. We can fix it, but maybe later. First focus on those critical bugs.

@znw0714 thanks for the feedback. If you have any further suggestion to solve this problem, please feel free to add a comment. I will keep this issue open.
