【发布时间】：2016-12-17 14:41:51
【问题描述】：

我需要将 Angular 升级到 rc5 才能使用 NgModule。

我已关注directions from Angular 2。

我已经更新了我的 package.json 依赖项，然后在终端中运行 npm stall：

  "dependencies": {
    "@angular/common": "^2.0.0-rc.5",
    "@angular/compiler": "^2.0.0-rc.5",
    "@angular/core": "^2.0.0-rc.5",
    "@angular/forms": "0.3.0",
    "@angular/http": "2.0.0-rc.5",
    "@angular/platform-browser": "^2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "^2.0.0-rc.5",
    "@angular/router": "3.0.0-beta.1",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "@angular/upgrade": "2.0.0-rc.5",
    "angular2-google-maps": "^0.12.0",
    "angular2-in-memory-web-api": "0.0.14",
    "bootstrap": "^3.3.6",
    "core-js": "^2.4.0",
    "jquery": "v3.1.0",
    "ng2-select": "^1.0.3",
    "reflect-metadata": "^0.1.3",
    "rxjs": "5.0.0-beta.6",
    "systemjs": "0.19.27",
    "zone.js": "^0.6.12"
  },

最终结果：

我已经尝试过 Angular 2 建议的其他选项：

npm install @angular/{core,common,compiler,platform-browser,platform-browser-dynamic} --save

无论我做什么升级，我都会遇到同样的未满足的对等依赖项错误。

解决我尝试过的问题：

npm install @angular

请注意，这是一个工作的 angular 2 应用程序，所以我似乎确实安装了 angular 2。如何满足我的对等依赖项以便我可以升级到 angular2 rc5？

【问题讨论】：

    标签： angular npm npm-install package.json


    【解决方案1】：

    你试过新鲜的npm install吗？绝对会推荐。还要尝试事先清理缓存以确保您没有先前的冲突：

    rm -rf node_modules/
npm cache clean
npm install

    我还建议您将路由器更新为3.0.0-rc.1。这是最新版本。

    编辑：我还建议您删除您的 node_modules 目录并安装一个新目录：rm -rf node_modules。

    【讨论】：

    • 也许我会在之前清空 package.json 中的旧依赖项并使用 --save 标志，..
    • 让我在 mac 上遇到了恢复 node_modules 的问题 :(，不要删除根 node_modules，做错了
    【解决方案2】：

    您收到此错误的原因是因为您将"angular2-google-maps": "^0.12.0" 与 angular2 一起使用。现在"angular2-google-maps" 是对等依赖于angular 2.0.0-rc.2 版本，这就是错误状态：

    npm WARN EPEERINVALID angular2-google-maps@0.12.0 requires a peer of @angular/common@2.0.0-rc.2 but none was installed.

    这仍然是一个悬而未决的问题，如 here 所示。

    • 我建议你要么使用angular 2.0.0-rc.2，直到它得到 解决。
    • 第二种方法是使用npm i https://github.com/SebastianM/angular2-google-maps/tarball/0.12.0 --save 安装google-maps。

    希望对你有帮助！

    编辑：他们将在几天内发布0.13.0 版本，该版本将与rc5 兼容。更多信息请看here

      【解决方案3】：

      如果还是有问题可以试试

      npm --depth Infinity update

      【讨论】：

        【解决方案4】：

        这是我也面临的同样问题-

        我只是更新 npm-

        sudo npm install npm -g

        我的问题解决了！！！
