当使用"离子服务"；最近生成的应用程序上的命令我遇到错误

[ng] internal/modules/cjs/loader.js:883
[ng]   throw err;
[ng]   ^

我曾多次尝试通过新的安装卸载node.js、angular/cli和cordova ionic，但似乎都不起作用。我迷失了方向

Option 1: edit your Windows installation's PATH to put %appdata%npm before %ProgramFiles%nodejs.   Remember that you'll need to restart cmd.exe (and potentially restart Windows) when you make changes to PATH or how npm is installed.
Option 2: remove both of
%ProgramFiles%nodejsnpm
%ProgramFiles%nodejsnpm.cmd
