有没有人有办法？安装它真的很让人头疼。非常感谢!

Answer 1

一种快速的解决方法是使用sudo pip install praw命令将praw安装为超级用户。但是，不建议这样做，因为这可能会在以后的更新和向上扩展应用程序等方面造成问题。相反，有人会建议你使用create a virtual environment，并在其中使用pip install praw。

如果您确信您正在构建的应用程序不会变得太大，那么使用sudo安装praw可能是可以的。

我得到了与您相同的错误，并且我在reddit documentation for PRAW中找到了答案。我使用HomeBrew来安装pip，并且我使用的是Python3.x而不是OSX附带的2.7x，这意味着我需要使用pip3而不是pip。它很快就起作用了。

我希望这能帮到你!
