xcode-select -install对我不起作用(Macos Catalina 10.15.7)，因为它显示了一个软件更新对话框，该盒说Can't install the software because it is currently not available from the Software Up date Server.$ sudo xcode-select -switch /Library/Developer/CommandLineTools Applications/Xcode.app/Contents/Developer # only for the (II) uninstalling case - install tools (again) if you don't get a default installation prompt # only for the (II) uninstalling case - the next line deletes folder returned by the `xcode-select -print-path` command Sudo xcode-select -switch /Library/Developer/CommandLineTools # could be useful if the path is making a problem # in my case it printed `/Library/Developer/CommandLineTools`
