我尝试根据 angular-cli wiki 安装第 3 方 npm 模块:https://github.com/angular/angular-cli/wiki/3rd-party-libs 但失败了.我已经为此苦苦挣扎了好几天，非常感谢您的帮助.

I try to install a 3rd party npm module according to the angular-cli wiki: https://github.com/angular/angular-cli/wiki/3rd-party-libs but fail. I've been struggling with this for days now and would greatly appreciate any help.

获取错误的步骤:

ng 新的 lodashtest3cd lodashtest3npm 安装 lodash --save打字安装 lodash --ambient --save

angular-cli-build.json:

angular-cli-build.json:

module.exports = function(defaults) {返回新的 Angular2App(默认值，{供应商Npm文件:[...'lodash/**/*.js']});};ng build(lodash 正确添加到 dist/vendor 中)

module.exports = function(defaults) { return new Angular2App(defaults, { vendorNpmFiles: [ ... 'lodash/**/*.js' ] }); }; ng build (lodash gets correctly added in dist/vendor)

system-config.ts:

system-config.ts:

/** Map relative paths to URLs. */
 const map: any = {
   'lodash': 'vendor/lodash/lodash.js'
 };

 /** User packages configuration. */
 const packages: any = {
   'lodash': {
     format: 'cjs'
   }
 };

(全部根据规范https://github.com/angular/angular-cli/wiki/3rd-party-libs)注意 - 我已经尝试了我能想到的所有配置设置，都给出了相同的结果.

(all according to spec in https://github.com/angular/angular-cli/wiki/3rd-party-libs) Note - I've tried all config settings I can think of here, all giving the same result.

推荐答案

使用稳定版本和当前的 angular-cli (1.0.0-beta.15)，只需添加 npm 包和类型定义

With the stable release and current angular-cli (1.0.0-beta.15), it's simply adding the npm package plus type definitions

npm install lodash --save
npm install @types/lodash --save-dev

对于 1.0.0-beta.15 等早期版本，下一个是必要的.当前版本不需要它:

For early versions such as 1.0.0-beta.15, the next is necessary. It should not be required for current versions:

将库添加到 angular-cli.json 到全局脚本列表(添加 "../node_modules/lodash/lodash.js" 到列表 <代码>apps[0].scripts).

Add the library to the angular-cli.json to list of global scripts (add "../node_modules/lodash/lodash.js" to the list apps[0].scripts).
