正在卸载Mac OS Catalina上的所有“pip”软件包

Question

试图卸载Mac上的所有pip和pip3软件包，但我遇到了以下错误，这些错误主要与OSError: [Errno 30] Read-only file system:和[Errno 1] Operation not permitted:有关。我已经试过：

• 使用csrutil disable并在禁用csrutil时运行卸载命令
• 在禁用csrutil时尝试sudo -H卸载

以下是错误：

第一：SIP状态以及pip和pip3信息

$ csrutil status
System Integrity Protection status: disabled.

$ pip list
zsh: command not found: pip

$ python -m pip list
