检测到Angular Compiler但它是错误类的一个实例

错误：

ERROR in ./src/main.ts
Module build failed: Error: Angular Compiler was detected but it was an instance of the wrong class.
This likely means you have several @ngtools/webpack packages installed. You can check this with `npm ls @ngtools/webpack`,and then remove the extra copies.

我已经尝试了所有可能的想法

>删除node_module文件夹和Package.lock.json
>重新安装npm – npm安装
>尝试了npm更新

在这里任何关于失踪的帮助将非常感谢我被困在这里.

———————————

经过大量研究后,我能够通过将package.json更改为下面来解决此问题

{
  "name": "app1","dependencies": {
    "@angular/animations": "^5.2.0","@angular/cdk": "^5.2.4","@angular/material": "^5.2.4","ng2-tooltip": "0.0.7","webpack": "^2.5.1","devDependencies": {
    "@angular/cli": "~1.7.2","@angular/compiler-cli": "^5.2.0","@angular/language-service": "^5.2.0","@types/jasmine": "~2.8.3","@types/jasminewd2": "~2.0.2","@types/node": "~6.0.60","codelyzer": "^4.0.1","jasmine-core": "~2.8.0","karma": "~2.0.0","karma-coverage-istanbul-reporter": "^1.2.1","karma-jasmine": "~1.1.0","protractor": "~5.1.2","ts-node": "~4.1.0","tslint": "~5.9.1","typescript": "~2.5.3"
  }
}

但仍然有一个问题说.

ERROR in No NgModule metadata found for 'AppModule'.
