The issue here is that you are attempting to upgrade the setuptoolsthat came installed in your system Python, which requires changes to areas of the file system a "normal" user won't have (it requires root privileges).
这里的问题是您正在尝试升级setuptools系统 Python 中安装的程序，这需要更改“普通”用户不会拥有的文件系统区域（它需要 root 权限）。
Prefixing the command with sudomight help, but you should ask yourself whether you really want to change the system Python, since some OSs require Python "as installed" for various system purposes.
为命令添加前缀sudo可能会有所帮助，但您应该问问自己是否真的要更改系统 Python，因为某些操作系统需要 Python“按安装”用于各种系统目的。
It's a lot safer to install a second copy of Python somewhere you have write access to (I personally tend to use /usr/localbut YMMV) and then you won't need to worry about breaking your system. Further, as long as you set your PATH to include /usr/local/binyou can just use the pythoncommand to run it.
在你有写权限的地方安装 Python 的第二个副本要安全/usr/local得多（我个人倾向于使用但 YMMV），然后你就不必担心破坏你的系统了。此外，只要您将 PATH 设置为包含，/usr/local/bin您就可以使用该python命令来运行它。
