第一次使用 firestore 时出现此错误。根据我的研究，这似乎是 Ivy 的问题。我没有很多修改 tsconfig.app.json 的经验，这是我被指出的方向，遵循其他答案。

我能够从原始项目中修改的唯一一件事是使用 Angular Fire 6 而不是 5，这是我最初按照教程所做的。

这是 package.json：

{
  "name": "language",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "~9.0.1",
    "@angular/cdk": "^9.0.0",
    "@angular/common": "~9.0.1",
    "@angular/compiler": "~9.0.1",

    "@angular/flex-layout": "^9.0.0-beta.29",
    "@angular/forms": "~9.0.1",

    "@angular/platform-browser": "~9.0.1",
    "@angular/platform-browser-dynamic": "~9.0.1",
    "@angular/router": "~9.0.1",
    "firebase": "^7.8.2",
    "rxjs": "~6.5.4",
    "rxjs-compat": "^6.5.4",
    "tslib": "^1.10.0",
    "zone.js": "~0.10.2"
  },
  "devDependencies": …

我正在学习 Angular Material 并且在从“@angular/material/button”导入 { MatButtonModule } 时出现此错误。

从我在其他答案中读到的内容来看，它看起来像是包兼容性问题，但我无法修复它。

这是完整的错误

我在 SO 中遇到了类似的错误，但是在安装、删除 node-modules、package-lock.json 再次安装后，我仍然无法摆脱错误：

./src/app/app.module.ts:8:0-63 - 错误：找不到模块：错误：包路径 ./module 未从包 /Users/pabs/FreeLance/Chris/Calculator/stamp/node_modules 导出/@angular/flex-layout （请参阅 /Users/pabs/FreeLance/Chris/Calculator/stamp/node_modules/@angular/flex-layout/package.json 中的导出字段）

通过 VSCode 的源控制区域意外删除项目后，Omnisharp 完全停止工作。任何以前的项目和任何新创建的项目都不起作用。在 Visual Studio 上一切正常，所以我认为问题不在于 .NET Core 安装。我在 Mac 上。

    "message": "The type or namespace name 'System' could not be found (are you missing a using directive or an assembly reference?) [API, API, API]"

我试过的：

• 重新安装 .Net Core 3.1（无需先卸载）
• 彻底删除VSCode（包括隐藏目录，缓存，一切）
• 在网络上找到更简单的解决方案，例如重建、重启 omnisharp 等。

任何帮助表示赞赏，谢谢！
