请注意 brew 也失败了，它找不到它。

Notice that brew also fails, it cannot find it.

推荐答案

在系统范围的Python上安装库通常是个坏主意。请为每个项目使用virtualenv。

It's generally a bad idea to install libraries on your system-wide Python. Use a virtualenv for each project instead.

首先安装 virtualenv 在您的Mac上全球：

First install virtualenv globally on your Mac:

$ [sudo] pip install virtualenv

然后使用 virtualenv 命令创建Python可执行文件的新（副本）：

Then use virtualenv command to create a new (a copy) of Python executable:

$ cd your/prefred/folder
$ virtualenv your_project

激活 virtualenv ：

$ source your_project/bin/activate

您的virtualenv已创建并激活（提示已更改为显示激活）。您可以在其中安装任何内容：

Your virtualenv is created and activated (the prompt is changed to show the activation). You can install anything in it:

$ pip install -U scikit-image
