错误：找不到模块@ ionic / cli-utils

Question

我试图在终端中运行离子并遇到以下错误：

module.js:487
    throw err;
    ^

Error: Cannot find module '@ionic/cli-utils'
    at Function.Module._resolveFilename (module.js:485:15)
    at Function.Module._load (module.js:437:25)
    at Module.require (module.js:513:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (/usr/local/lib/node_modules/ionic/dist/index.js:14:21)
    at Module._compile (module.js:569:30)
    at Object.Module._extensions..js (module.js:580:10)
    at Module.load (module.js:503:32)
    at tryModuleLoad (module.js:466:12)
    at Function.Module._load (module.js:458:3)

我在谷歌上环顾四周但却找不到任何错误原因。有什么想法吗？

Answer 1

更新新版本时也发生在我身上。解决它：

1. 删除 node_modules
2. 删除 package-lock.json 文件
3. 运行 npm install 命令
4. ionic serve

Answer 2

在将Ionic更新为最新版本（目前为3.9.2）时发生了。 解决了它做到以下几点：

• 删除package-lock.json文件
• 删除node_modules/文件夹

• 将package.json个文件依赖项和devDependencies部分编辑为：

  "dependencies": {
      "@angular/common": "4.1.3",
      "@angular/compiler": "4.1.3",
      "@angular/compiler-cli": "4.1.3",
      "@angular/core": "4.1.3",
      "@angular/forms": "4.1.3",
      "@angular/http": "4.1.3",
      "@angular/platform-browser": "4.1.3",
      "@angular/platform-browser-dynamic": "4.1.3",
      "@ionic-native/core": "3.12.1",
      "@ionic-native/splash-screen": "3.12.1",
      "@ionic-native/status-bar": "3.12.1",
      "@ionic/storage": "2.0.1",
      "ionic-angular": "3.6.0",
      "ionicons": "3.0.0",
      "rxjs": "5.4.0",
      "sw-toolbox": "3.6.0",
      "zone.js": "0.8.12"      
  },
  "devDependencies": {
      "@ionic/app-scripts": "2.1.3",
      "typescript": "2.3.4"
  }
  

• 再次运行npm install

• 编辑www/index.html文件中的脚本部分：

  <script src="build/polyfills.js"></script>
  <script src="build/vendor.js"></script>
  <script src="build/main.js"></script>
