点安装--target =. Alfred-Workflow出现错误 [英] Pip install --target=. Alfred-Workflow gives an error

问题描述

我正在尝试通过这些说明在macOS上安装python库

I am trying to install a python library on macOS following through these instructions.

但是，每次运行此命令时，我都会出错:pip install --target=. Alfred-Workflow

However I get an error every time I run this command : pip install --target=. Alfred-Workflow

我总是会因运行它而收到此错误:

And I always get this error for running it :

pip install --target=. Alfred-Workflow       
Collecting Alfred-Workflow
Installing collected packages: Alfred-Workflow
Exception:

我尝试使用谷歌搜索并进行搜索，但仍然无法解决.谢谢您的帮助.

I tried googling and searching for this but still can't figure it out. Thank you for any help.

推荐答案

This question answers that (I found it when googling for the last line of your error message).

首先，我也得到了与您相同的错误消息，但是这样做之后:

First I also got the same error message as you did, but after doing this:

$ echo "[install]
prefix=" > ~/.pydistutils.cfg

有效:

$ pip install --target=. Alfred-Workflow
Collecting Alfred-Workflow
Installing collected packages: Alfred-Workflow
Successfully installed Alfred-Workflow-1.24

重要提示:它会破坏常规的pip install命令，因此您需要随后rm ~/.pydistutils.cfg.

Important note: it breaks normal pip install commands, so you need to rm ~/.pydistutils.cfg afterward.
