点子安装--target =.Alfred-Workflow给出了一个错误

我试图通过这些说明在macOS上安装python库.

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

我总是得到这个错误来运行它:

pip install --target=. Alfred-Workflow       
Collecting Alfred-Workflow

我试着谷歌搜索并搜索这个,但仍然无法弄明白.感谢您的任何帮助.

这个问题回答了(我在谷歌搜索你的错误信息的最后一行时发现了它).

首先,我也得到了与您相同的错误消息,但在执行此操作后:

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

有用:

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

重要说明:它会破坏正常pip install命令,因此您需要在rm ~/.pydistutils.cfg以后执行.
