pip安装pkg拒绝许可: /Library/Python/2.7/site-packages/pkg

Question

有趣的是，今天重新安装Python2后，使用brew reinstall python在自制。

异常

$ which python
/usr/local/bin/python

$ echo $PYTHONPATH
$

非常肯定，这是使用OS系统Python，但无法解决如何。

好的-自制软件想让我在重新安装后使用pip2而不是pip。

我可能应该读一下文档，但这不是主要问题.

文件/usr/local/bin/pip的顶部行现在是#!/usr/local/opt/python/bin/python2.7。

这就是问题所在。将此行更改为：

A. #!/usr/local/bin/python或

B. #!`brew --prefix`/bin/python

解决问题。

注:我不能百分之百地把这归咎于自制。请注意这里发生了什么，但问题已经解决了。

而且，我本来可以运行sudo pip ...，但这会扰乱macOS系统site-packages目录，这通常被认为不是一个好主意。
