如何解决在使用 Angular-CLI 和 RC.4 以及 AngularFire 2 和 Firebase 3 时找不到模块 'angularfire2'

How to resolve Cannot find module 'angularfire2' when using Angular-CLI and RC.4 with AngularFire 2 and Firebase 3

我正在使用 angular-cli 和最新的 Angular RC4 版本。

我正在按照步骤 here

但我不得不做一些非常小的改变。首先,我以这种方式安装 AngularFire: npm install git+https://github.com/angular/angularfire2.git --save 这样我就有了一个与 RC4 兼容的版本。

其次,在执行打字步骤时,我这样做: typings install file:node_modules/firebase/firebase.d.ts --save --global && typings install 因为那是 firebase.d.ts 文件现在的位置。

接下来我这样做:

var map = {
    'firebase': 'vendor/firebase/firebase.js',
    'angularfire2': 'vendor/angularfire2'
};

/** User packages configuration. */

var packages = {
    angularfire2: {
        defaultExtension: 'ts',
        main: 'angularfire2.ts'
    }
};

我使用 .ts 文件的地方是因为 node_modules/angularfire2 文件夹中没有 angularfire2 的 .js 文件。即使在源文件夹中,它也只是 .ts 文件。

所以,一旦我进入第 7 步,并执行此操作:

import { FIREBASE_PROVIDERS, defaultFirebase } from 'angularfire2';

一切都崩溃了。我不确定为什么,它应该有用吗?

here's the project on github

更新:

因此,我尝试在 system-config.ts 中将扩展名从 .ts 更改为 .js。

然后,我尝试了以下操作:

➜ Projects rm -rf angular-analytics 
➜ Projects npm uninstall -g angular-cli
➜ Projects npm cache clean
➜ Projects npm install -g angular-cli@latest
➜ Projects git clone git@github.com:thehashrocket/angular-analytics.git
➜ Projects cd angular-analytics 
➜ angular-analytics git:(master) npm install
➜ angular-analytics git:(master) ng build

然而,结果是这样的(再次):

我是不是真的很笨,漏了一步?我觉得我是。 . .这将是一些我不知道或完全忽视的显而易见的事情。 :(

对于 firebase,您的输入应该如下所示:

"dependencies": {
  "es6-promise": "github:typed-typings/npm-es6-promise#fb04188767acfec1defd054fc8024fafa5cd4de7",
  "firebase": "github:typed-typings/npm-firebase"
},

你的 package.json 应该有 AngularFire2。它适用于 Angular 2 RC.4:

"angularfire2": "2.0.0-beta.2",

使用 npm install -g npm 应该会得到 npm 版本 3.10.5,这不会因为对等依赖项不是 Angular 2 RC.2.

而失败

看起来你的回购协议是私人的,因为 link 是 404。所以我无法真正测试它或看到你遇到的确切问题,但希望这会有所帮助。

  1. 从 node_modules
  2. 中删除 firebase 和 angularefire2 文件夹
  3. 在 Package.json 中将您的 angularfire2 和 firebase 依赖项更改为如下所示:

    Package.json

  4. npm 安装

  5. ng 服务

一个更简单的解决方案是更改 import 语句以导入已弃用的模块,而不是:

从'angularfire2/database'导入{AngularFireDatabase};

使用这个:

从'angularfire2/database-deprecated'导入{AngularFireDatabase};

这将解决订阅错误,无需更改 package.json 或删除任何内容。
