IntelliJ & Angular2 / TypeScript - error TS2307:无法找到模块‘angular2 2/.’

Question

关于这个问题，似乎有很多问题和答案，但到目前为止，我发现的大多数答案都是针对Windows / Visual的。我正在使用OSX和IntelliJ进行Angular2 with TypeScript项目，并且当我从angular2库导入时，当前在" from“位置下收到警告/错误(那些红色的小行)，例如在我的app.ts中：

/// <reference path="node_modules/angular2/ts/typings/node/node.d.ts"/>
/// <reference path="node_modules/angular2/typings/browser.d.ts"/>

import { bootstrap } from "angular2/platform/browser";
import { Component } from "angular2/core";
import { ROUTER_DIRECTIVES, ROUTER_PROVIDERS, RouteConfig} from 'angular2/router';

所有3个import语句都在from位置(我们有“angular2/.”)下有警告。我试图在Intellij中通过editiing类型- tried piler.xml来纠正这一点：

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="TypeScriptCompiler">
    <option name="isCompilerEnabled" value="true" />
    <option name="typeScriptServiceDirectory" value="$USER_HOME$/node_modules/typescript/bin" />
    <option name="typeScriptCompilerParams" value="-m amd -t ES5" />
    <option name="versionType" value="SERVICE_DIRECTORY" />
  </component>
</project>

我导入的所有其他模块都很好(就像我自己编写的组件)，但是我从Angular2导入的模块有警告吗？是否有人设法克服了这个错误/问题，因为我已经尝试了一段时间来消除这个问题。我现在已经安装了1.7.5版本的TypeScript。

请注意，我的typings.json文件或npm typings没有安装在我的dev-dependancies中。

这是我的tsconfig.json文件：

Answer 1

对我来说，它是通过使用相对路径来修复的，即(取决于.ts文件的位置)：

///<reference path="../../node_modules/angular2/typings/browser.d.ts"/>

另外，在Intellij设置中，请确保启用"Use tsconfig.json“。我的设置文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="TypeScriptCompiler">
    <option name="isCompilerEnabled" value="true" />
    <option name="typeScriptCompilerParams" value="--module &quot;amd&quot; --target &quot;ES5&quot; --experimentalDecorators" />
    <option name="useConfig" value="true" />
  </component>
</project>

请注意，自从angular2 rc.1 被释放几个小时以来， (https://github.com/angular/angular/blob/3229bf16656749427d1def38ced0e1d1d2ae1fa4/CHANGELOG.md)

这就引入了一些关于如何导入模块的重大更改(例如，“角/核心”获取“@角/核心”)。

如果您正在使用rc版本，那么您不再需要///<reference path=".."/>了。System.js自动在node_modules目录中找到相应的index.d.ts (如果设置正确：https://github.com/angular/quickstart/blob/master/systemjs.config.js)

我还必须将目标更改为ES6，否则会收到错误消息，例如Map或Promise未定义。如果仍然希望保留ES5目标，则需要包括es6-shim (.js和.d.ts)
