我正在尝试使用 InversifyJS 设置 NodeJS/TypeScript 项目,但在起步时遇到了一些麻烦。在过去的几天里,我一直在研究这个问题,但无法弄清楚问题所在。一切都正确构建,但是当我尝试启动节点服务器时,出现以下错误:
TypeError: inversify_1.injectable is not a function
我正在运行 NodeJS v6.2.2 (Windows 10 x64) 并安装了 TypeScript 1.8。我尝试使用 VS2015 和 gulp 进行构建。下面是我尝试过的一个最小示例,它遇到了同样的错误。我看不出有什么问题,但我一定遗漏了一些明显的东西。(除了草率的代码,它应该仍然可以工作。)
服务器.ts:
/// <reference path="./node_modules/reflect-metadata/reflect-metadata.d.ts" />
/// <reference path="./node_modules/inversify-dts/inversify/inversify.d.ts" />
/// <reference path="./typings/index.d.ts" />
import "reflect-metadata"
import { Application } from "./app/app"
import { ITest, TestClass } from "./app/testclass"
import { Kernel, injectable, inject } from "inversify"
var kernel = new Kernel();
kernel.bind<ITest>("ITest").to(TestClass);
kernel.bind<Application>(Application).to(Application);
var app = kernel.get<Application>(Application);
app.initialize();
应用程序/app.ts
/// <reference path="../node_modules/inversify-dts/inversify/inversify.d.ts" />
/// <reference path="../typings/index.d.ts" />
import * as Hapi from "hapi";
import { inject, injectable } from "inversify"
import { ITest } from "../app/testclass"
@injectable()
export class Application {
private testClass: ITest;
constructor( @inject("ITest") test: ITest) {
this.testClass = test;
};
initialize() {
var server = new Hapi.Server({
connections: {
router: {
isCaseSensitive: false,
stripTrailingSlash: true
}
}
});
server.connection({
port: '3000',
host: 'localhost'
});
server.route({
method: 'GET',
path: '/',
handler: (request: Hapi.Request, reply: Hapi.IReply) => {
var str = this.testClass.test();
reply(str);
}
});
server.start(function () {
console.log('Server running at:', server.info.uri);
});
}
}
应用程序/testclass.ts
/// <reference path="../node_modules/inversify-dts/inversify/inversify.d.ts" />
import { injectable } from "inversify"
export interface ITest {
test(): string;
}
@injectable()
export class TestClass implements ITest {
test(): string {
return "testing";
}
}
