[英]Nodejs/Typescript error: SyntaxError: Unexpected token :
我在名为 spartan.ts 的单独文件中定义了一个类,它是这样的:
class Spartan {
name: string;
constructor(name: string) {
this.name = name;
}
test() {
return this.name;
}
}
module.exports = Spartan;
然后我将其导入其他文件,如下所示:
var Spartan = require("../entities/spartan.ts");
var mySpartan = new Spartan("myName");
console.log(mySpartan.test())
我的 tsconfing.json 看起来像这样:
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"module": "es2015",
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2017",
"dom"
]
}
}
然后我得到这个错误:
SyntaxError: Unexpected token :

您可能应该使用 ES2015 模块语法进行导入/导出,例如:
export class Spartan {
name: string;
constructor(name: string) {
this.name = name;
}
test() {
return this.name;
}
}
进而:
import { Spartan } from "../entities/spartan.ts";
let mySpartan = new Spartan("myName");
console.log(mySpartan.test())
