Python 安装praw时出错

我在尝试使用pip安装praw时遇到一些异常。以下是我收到的错误消息：

MacBook:usr name_r$ pip install praw

Storing debug log for failure in /var/folders/qz/q26gj5zx62d3d206hdnn_rwm0000gn/T/tmp_wCuvN

有人能告诉我这是怎么回事吗？我是否需要以某种方式更新Python，还是pip有问题

如何让它正确安装praw

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/os.py", line 157, in makedirs
    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/praw'

似乎您正在Mac上运行，您需要更改为root用户进行安装，否则您没有该文件夹的写入权限。sudo-s将更改为root

谢谢！完全错过了这个！
