如何使用此权限错误，并使virtualenv正常工作？

Answer 1

在运行/修改默认的OSX python解释器时，我总是遇到权限问题。目前我使用PyEnv（https://github.com/yyuu/pyenv）安装单独的用户可修改的python解释器，并与pyenv-virtualenv（https://github.com/yyuu/pyenv-virtualenv）一起使用它就像一个魅力。自改变以来，我一直没有遇到任何问题。

Answer 2

我最近有类似的问题设置新机器，我发现这个解决方案效果最好。 https://apple.stackexchange.com/a/209583/226131

更详细的解释包含在同一个问题中。 https://apple.stackexchange.com/a/223163/226131

TLDR：安装python brew install python的用户可修改版本，然后就可以进行安装。
