【问题描述】：

在最近生成的应用程序上使用“ionic serve”命令时遇到错误

[ng] The system cannot find the path specified.
[ng] internal/modules/cjs/loader.js:883
[ng]   throw err;
[ng]   ^
[ng] Error: Cannot find module 'C:\Users\shane\College\Year 2\Semester 2\Mobile Application Development\Ionic\@angular\cli\bin\ng'
[ng]     at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)
[ng]     at Function.Module._load (internal/modules/cjs/loader.js:725:27)
[ng]     at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12)
[ng]     at internal/main/run_main_module.js:17:47 {
[ng]   code: 'MODULE_NOT_FOUND',
[ng]   requireStack: []
[ng] }

[ERROR] ng has unexpectedly closed (exit code 1).

我曾多次尝试卸载 node.js、angular/cli 和 cordova ionic 并进行全新安装，但似乎没有任何效果。我迷失了从这里去的地方

【解决方案1】：

这个错误表示设置了环境变量
全局安装最新的 npm 包

npm install -g npm@latest

second thing is you follow this   
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%\nodejs\npm
%ProgramFiles%\nodejs\npm.cmd
