我正在尝试在Angular2项目(RC.0)中使用DefinitelyTyped中的typescript tsd,但是全局依赖项似乎没有正确加载:
typings install --save dt~hellojs --global --save
npm install --save hellojs
我有这样的配置:
typings.json:
"globalDependencies": {
"hellojs": "registry:dt/hellojs#0.2.3+20160423145325"
}
angular.cli.build.js:
module.exports = function(defaults) {
return new Angular2App(defaults, {
vendorNpmFiles: [
'systemjs/dist/system-polyfills.js',
'systemjs/dist/system.src.js',
'zone.js/dist/**/*.+(js|js.map)',
'es6-shim/es6-shim.js',
'reflect-metadata/**/*.+(js|js.map)',
'rxjs/**/*.+(js|js.map)',
'@angular/**/*.+(js|js.map)',
'angular2-moment/**/*.+(js|js.map)',
'moment/**/*.+(js|js.map)',
'hellojs/**/*.+(js|js.map)'
]
});
};
系统config.ts
/** Map relative paths to URLs. */
const map: any = {
'moment': 'vendor/moment',
'angular2-moment': 'vendor/angular2-moment',
'hellojs': 'vendor/hellojs/dist'
};
/** User packages configuration. */
const packages: any = {
'moment': { main: 'moment.js', defaultExtension: 'js' },
'angular2-moment': { main: 'index.js', defaultExtension: 'js' },
'hellojs': { main: 'hello.all.js' }
};
但是,如果我使用角度模块中的新依赖项,如下所示:
import {Component} from "@angular/core";
import {FormBuilder, ControlGroup} from "@angular/common";
import {ROUTER_DIRECTIVES, Router} from "@angular/router";
import {LoginResourceService} from "../shared/services/resources/login-resource.service";
import {AuthService} from "../shared/services/auth.service";
import {AppRoutes} from "../app-routes";
@Component({
moduleId: module.id,
selector: 'app-login',
templateUrl: 'login.component.html',
directives: [ROUTER_DIRECTIVES],
providers: [LoginResourceService],
styleUrls: ['login.component.css']
})
export class LoginComponent {
userForm:ControlGroup;
errorMessage:string;
constructor(formBuilder:FormBuilder, private _loginResource:LoginResourceService, public router:Router,
private _auth:AuthService) {
this.userForm = this.buildLoginForm(formBuilder);
}
// ...
example() {
hello.init({});
}
}
我收到了编译错误:
Error: Typescript found the following errors:
/Users/fer2d2/dev/personal/web-projects/front-joinfinity/tmp/broccoli_type_script_compiler-input_base_path-xa8whw1k.tmp/0/src/app/+login/login.component.ts (62, 5): Cannot find name 'hello'.
如果我尝试使用import * as hello from "hellojs"
或import hello = require("hellojs")
导入模块,则失败仍然存在。
如何使用Angular2中的globalDependency?
提前致谢。
修改
使用:
import {hello} from "hellojs"
或
import hello from "hellojs"
或
import hello = require("hellojs")
我收到了这个错误:
Error: Typescript found the following errors: /Users/fer2d2/dev/personal/web-projects/front-joinfinity/tmp/broccoli_type_script_compiler-input_base_path-tKuuBwei.tmp/0/src/app/+login/login.component.ts (7, 21): Cannot find module 'hellojs'.
似乎Typescript或systemjs没有正确地加载globalDependencies tsd。
答案 0 :(得分:0)
最后我解决了我的问题:
在Angular2中,使用和使用Angular-CLI,您有一个名为typings.d.ts的文件,它导入通过typings install
安装的所有类型。在此文件中,您可以看到以下导入行:
/// <reference path="../typings/browser.d.ts" />
browser.d.ts只包含Angular2在其他一些类型之间的输入。如果要使用globalDependencies,typings
会将它们添加到文件typings / index.d.ts中。因此,在您的typings.d.ts中,您必须添加以下行:
/// <reference path="../typings/browser.d.ts" />
我的问题似乎与最新的打字更新有关,其中&#39; ambient&#39;被全球&#39;取代作为此依赖项的前缀。
