Visual Studio Code：Angular 项目中的“找不到‘tslib’”错误

柯克·塞夫奇克

基本上，我所做的就是启动一个新的 Angular 项目并将其加载到工作区中。由于此错误，VS Code 似乎无法执行任何 linting 或代码意义。它吐出这个错误数据：

{
    "resource": "/Users/<snip!>/angular-project/src/app/app.module.ts",
    "owner": "typescript",
    "code": "2354",
    "severity": 8,
    "message": "This syntax requires an imported helper but module 'tslib' cannot be found.",
    "source": "ts",
    "startLineNumber": 13,
    "startColumn": 1,
    "endLineNumber": 26,
    "endColumn": 3
}

我发现了一个旧的错误的地方，说moduleResolution的tsconfig.json已经被设置为node，但角度CLI已经这样做了，我...

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "esnext",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  }
}

编辑：我到达这里的步骤（在撰写本文时使用版本 8）：

安装 Angular CLI： $ npm install -g @angular/cli
创建项目： $ ng new angular-project
服务项目： $ ng serve

有谁知道如何解决这个问题？

下面是我使用 angular 8 的 package.json 文件。检查您是否安装了 tslib。

同时删除 package-lock.json 并删除 node_modules 文件夹然后npm i再次运行
