brew重新安装Python

在自制软件上重新安装Python 2后，今天的情况很有趣

例外情况

非常确定这是在使用OS X系统Python，但无法确定如何使用。

好-homebrew希望我在重新安装后使用

pip2

而不是

pip

我可能应该读一下文件，但无论如何，这不是主要问题

文件

/usr/local/bin/pip

的顶行现在是

#/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--前缀“/bin/python

解决了这个问题

注意：我不能100%地把这归咎于自制。请注意此处发生的情况，但问题已为我解决

我还可以运行

sudopip…

，但这会弄乱macOS系统

目录，这通常被认为不是一个好主意
