错误:找不到模块 @ionic/cli-utils

Question

我正在尝试在终端运行离子，并且正在收到以下错误：

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)

我已经在Google上环顾四周，但找不到任何错误的理由。有什么想法吗？

Answer 1

在更新新版本时，它也发生在我身上。将其解决为：

1. delete node_modules
2. delete package-lock.json file
3. 运行 npm install 命令
4. 离子服务

Answer 2

在将离子更新为最新版本(当前3.9.2(时发生在我身上。解决了以下操作：

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

• 编辑 package.json文件依赖项和devDepentencies段为：

  "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

• www/index.html文件中的编辑脚本部分：

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

您的离子版本是什么？请输入一些离子信息如果是ionic3.x尝试npm i -g @ionic/cli -utils？我解决了它，
