Debian Linux Python PIP 在安裝某些套件的時候(pip install package)，遇到這個錯誤訊息：
defaulting to user installation because normal site-packages is not writeable normal site-packages is not writeable
於是直接把這個資料夾搬走看看(chmod 777 這些當然都測試過了)
mv ~/.local/lib/python3.9/site-packages ~/.local/lib/python3.9/site-packages2
然後在重新安裝之類的，都遇到一樣無法寫入的問題~
Debian Linux 11 Python PIP 安裝遇到 site-packages is not writeable 解法
除了 site-packages is not writeable 的問題外，
使用 pip install --user <package-name> 遇到下述錯誤訊息：
deprecation: gpg 1.14.0-unknown has a non-standard version number. pip 24.1 will enforce this behaviour change. a possible replacement is to upgrade to a newer version of gpg or contact the author to suggest that they release a version with a conforming version number.
查了很久就不多說了，總之最後面的問題就是，pip 安裝的和 Debian 的 python3-gpg 套件不合，解法：
- sudo apt remove python3-gpg
這個問題解掉後，再來安裝套件：pip install --user <package-name> 就全部正常了.. @.@a..
