我试图通过these instructions在macOS上安装python库.
但是每次运行此命令时都会出错：pip install –target =.阿尔弗雷德 – 工作流程
我总是得到这个错误来运行它：
pip install --target=. Alfred-Workflow
Collecting Alfred-Workflow
Installing collected packages: Alfred-Workflow
Exception:

最佳答案
This问题答案(我在谷歌搜索你的错误信息的最后一行时发现它).
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
重要提示：它会破坏正常的pip install命令,因此之后需要rm~ / .pydistutils.cfg.
