Visual Studio Code：Angular 项目中的“'tslib' 找不到”错误答案

【问题标题】：Visual Studio Code: "'tslib' cannot be found" error in Angular projectVisual Studio Code：Angular 项目中的“'tslib' 找不到”错误
【发布时间】：2019-10-28 13:13:30
【问题描述】：

基本上，我所做的只是启动一个新的 Angular 项目并将其加载到工作区中。由于这个错误，看起来 VS Code 无法进行任何 linting 或代码感知。它正在吐出这个错误数据：

{
    "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
}

我在某处发现了一个旧错误，说必须将 tsconfig.json 中的 moduleResolution 设置为 node，但 Angular CLI 已经为我做到了...

{
  "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：我采取的步骤（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

有人知道怎么解决吗？

【问题讨论】：

什么是角度版本？您也可以上传显示错误的代码或截屏吗
我可以...但我尝试操纵代码以试图摆脱它，并且项目中任何被评估的代码都会给出相同的错误。
FWIW 我正在使用最新的 Angular 工具和 CLI。版本 8.0.2

【解决方案1】：

下面是我使用 Angular 8 的 package.json 文件。检查你是否安装了 tslib。

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