在Angular5项目中找不到命名空间'firebase'

Question

我试图在angular 5项目中集成angularfire2和firebase，但它给出了'firebase'命名空间错误。

的package.json

{
  "name": "angular5-firebase",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build --prod",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/core": "^5.0.0",
    "@angular/forms": "^5.0.0",
    "@angular/http": "^5.0.0",
    "@angular/platform-browser": "^5.0.0",
    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "@types/firebase": "^2.4.32",
    "angularfire2": "^5.0.0-rc.4",
    "core-js": "^2.4.1",
    "firebase": "^4.8.1",
    "rxjs": "^5.5.2",
    "typings": "^2.1.1",
    "zone.js": "^0.8.14"
  },
  "devDependencies": {
    "@angular/cli": "1.6.1",
    "@angular/compiler-cli": "^5.0.0",
    "@angular/language-service": "^5.0.0",
    "@types/jasmine": "~2.5.53",
    "@types/jasminewd2": "~2.0.2",
    "@types/node": "~6.0.60",
    "codelyzer": "^4.0.1",
    "jasmine-core": "~2.6.2",
    "jasmine-spec-reporter": "~4.1.0",
    "karma": "~1.7.0",
    "karma-chrome-launcher": "~2.1.1",
    "karma-cli": "~1.0.1",
    "karma-coverage-istanbul-reporter": "^1.2.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.1.2",
    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"
  }
}

我尝试过以下解决办法，但没有一个能解决我的问题。

• 从app.module.ts中的'firebase'导入*作为firebase;
• “types”：tsconfig.json中的[“firebase”]
• 使用'npm install --save @ types / firebase'安装@ types / firebase

在所有这些之后，我已经安装了firebase类型'typings install firebase --save'并在tsconfig.json中添加了“”文件“：[”typings / index.d.ts“]'。它从控制台中删除了命名空间的所有错误，但当我在浏览器中检查localhost：4200时，没有在那里呈现视图。通过检查元素，我可以看到没有渲染视图。

tsconfig.json

{
    "compileOnSave": false,
    "compilerOptions": {
        "outDir": "./dist/out-tsc",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es5",
        "typeRoots": [
            "node_modules/@types"
        ],
        "lib": [
            "es2017",
            "dom"
        ],
        "types": [
            "firebase"
        ]
    },
    "files": [
        "typings/index.d.ts"
    ]
}

您的问题已发布在此处：https://github.com/angular/angularfire2/issues/1387。

因此，当他们发布新版本时，你应该保留旧版本的firebase。

npm uninstall --save firebase
npm install --save [email protected]
