Answer 1

您在输出顶部有解释：

目录＆＃39; /Users/mostafa.osama2/Library/Caches/pip/http'或其父目录不归当前用户所有，并且已禁用缓存。请检查该目录的权限和所有者。如果用sudo执行pip，你可能需要sudo＆＃39; -H标志。

目录＆＃39; /Users/mostafa.osama2/Library/Caches/pip'或其父目录不归当前用户所有，并且已禁用缓存轮。检查该目录的权限和所有者。如果用sudo执行pip，你可能需要sudo＆＃39; -H标志。

首先要做的是将这些目录更改回用户，可能使用：

chown -R mostafa.osama2 /Users/mostafa.osama2/Library/Caches/pip

然后，您需要决定如何在本地应用程序或主目录中安装模块。除非您希望模块在系统范围内可见，否则您可以执行以下操作：

pip install --user -U pytest

无法在macOs上安装pytest高山脉
