以前，我一直在努力安装和运行几个python模块，因此我记得稍微移动文件.是什么导致了此错误?我怎样才能解决这个问题?我在Mac上.

Previously I had been struggling to install and run a couple of python modules so I remember moving files around a bit. Is that what has caused this error? How can I fix this? I am on Mac.

在此之前，我尝试安装bs4，并且收到类似的错误消息. (但我怀疑bs4安装有更多问题，所以这是稍后要讨论的另一个问题).

I was trying to install bs4 prior to this and I got similar error messages. (But i suspect the bs4 install has more issues so that's another question for later).

对于代码的任何格式问题，也深表歉意.尽力使它看起来像在终端上一样.

Also sorry for any format issues with the code. Have tried my best to make it look like it is on the terminal.

谢谢.

推荐答案

权限问题意味着您的用户权限不允许您在所需的文件夹(/Library/Python/2.7/site-packages/pip/)上进行写操作.您基本上可以做两件事:

A permission issue means your user privileges don't allow you to write on the desired folder(/Library/Python/2.7/site-packages/pip/). There's basically two things you can do:

1. 以sudo的身份运行pip:

1. run pip as sudo:

sudo pip install --upgrade pip

将pip配置为仅为当前用户安装，如.
