Question

开始ng服务时，我看到错误：

ERROR in lista-zadan-repo/node_modules/@angular/core/src/render3/ng_dev_mode.d.ts(9,11): error         
TS2451: Cannot redeclare block-scoped variable 'ngDevMode'.
node_modules/@angular/core/src/render3/ng_dev_mode.d.ts(9,11): error TS2451: Cannot redeclare block-scoped variable 'ngDevMode'.

我只是在容忍Angular，很难说在错误发生之前做了什么。也许Angular更新也可能是一个问题。我尝试了与此类似的其他stackoverflow主题中的所有解决方案，但没有帮助。我想解决问题而不是启动新项目。

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "importHelpers": true,
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],

    "lib": [
      "es2017",
      "dom"
    ]
  }
}

ng serve-无法重新声明块作用域变量'ngDevMode'
