Question

我使用 angular cli 构建项目。项目已运行，但错误出现在控制台中。

我点击了VM223并看到了

我想我忘了连接一些库或类似的东西。我怎么解决这个问题？有人可以体验这个吗？

当我使用 ng build -prod 时，我会得到文件夹dist，其中包含应用程序所需的样式，图像，字体和其他资源。但我认为必须有index.html和bundle文件，没有图像，字体等。

建成之后我有：

也许我做错了什么？

此致

Answer 1

您可能需要安装“require”软件包。

npm install require --save

应该这样做。

编辑：构建--prod是正常输出，它为您提供所需的所有静态文件，并捆绑css＆amp;的JavaScript。

EDIT2：你的浏览器出现了这个错误？ “Require”是一个Node.JS包，它是Server Sided Scripting，这意味着它可以在你的浏览器中使用。

看看这个：http://requirejs.org/对于客户端。

EDIT3：

var express = require('express')
var serveStatic = require('serve-static')

var app = express()

app.use(serveStatic('.', {'index': ['index.html']}))
app.listen(3000)

制作一个Server.js文件，将上面的代码放入其中，在构建之后将其放入dist中，然后运行以下命令

node Server.js

你可能需要安装express和serve-static，目的是检查它是否有效，将它们全部安装，你以后总是可以删除它们，然后在本地安装它们：

npm install -g express
npm install -g serve-static

Answer 2

首先删除节点模块：

并像这样制作你的pacage.json：

"dependencies": {
    "@angular/common": "2.3.1",
    "@angular/compiler": "2.3.1",
    "@angular/core": "2.3.1",
    "@angular/forms": "2.3.1",
    "@angular/http": "2.3.1",
    "@angular/platform-browser": "2.3.1",
    "@angular/platform-browser-dynamic": "2.3.1",
    "@angular/router": "3.3.1",
    "@types/gapi": "0.0.30",
    "@types/gapi.auth2": "0.0.34",
    "bootstrap": "3.3.7",
    "core-js": "2.4.1",
    "es6-promise": "3.0.2",
    "es6-shim": "0.33.3",
    "jquery": "3.1.1",
    "ng2-facebook-sdk": "1.2.0",
    "reflect-metadata": "0.1.8",
    "rxjs": "5.0.1",
    "ts-helpers": "1.1.1",
    "zone.js": "0.7.2"
  },
  "devDependencies": {
    "@types/core-js": "0.9.35",
    "@angular/compiler-cli": "2.3.1",
    "@types/jasmine": "2.5.38",
    "@types/node": "6.0.42",
    "@types/jquery": "2.0.40",
    "angular-cli": "1.0.0-beta.28.3",
    "codelyzer": "2.0.0-beta.1",
    "jasmine-core": "2.5.2",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "2.0.0",
    "karma-cli": "1.0.1",
    "karma-jasmine": "1.0.2",
    "karma-remap-istanbul": "0.2.1",
    "protractor": "4.0.13",
    "ts-node": "1.2.1",
    "tslint": "4.3.0",
    "typescript": "2.0.3"
  }

然后再次运行命令npm install，希望这对你有帮助。
