使用Python 3.6在Mac High Sierra上安装PyGame

Question

我在我的终端上安装了Homebrew，但是我被卡在这里。 它不会重新确认自制软件。 有人可以帮助我，以便使用Python 3.6安装Mac High Sierra的Pygame。

Answer 1

根据终端的输出，似乎Homebrew的安装未正确完成。

实际上，作为安装的一部分，Homebrew安装程序会尝试安装“ Xcode命令行工具”。 为此，它要求您按“返回”以确认您同意安装它们，然后要求您输入密码以获取执行权限。 也就是说，如果您按RETURN并输入密码，则Homebrew安装程序应该能够完成。

安装Homebrew之后，您可以使用brew命令安装Python，类似于您的第一次尝试：

brew install python

请注意， brew install python会安装Python3。如果要安装Python 2，请使用brew install python@2 。
