尝试按照官方手册实现一个模块,我得到这个错误消息:
Uncaught ReferenceError:未定义exports
在app.js: 2
但在我的代码中,我从未使用过名称exports。
我该如何解决这个问题?
文件
app.ts
let a = 2;
let b:number = 3;
import Person = require ('./mods/module-1');
模块- 1. t
export class Person {
constructor(){
console.log('Person Class');
}
}
export default Person;
tsconfig.json
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
"noImplicitAny": false,
"sourceMap": true,
"outDir": "scripts/"
},
"exclude": [
"node_modules"
]
}
我也有这个问题。然后我只是把“module”:“commonjs”改为“module”:“ESNext”,一切都正常工作。
这是tsconfig.json:
{
"compilerOptions": {
"module": "ESNext",
"esModuleInterop": true,
"target": "ESNext",
"moduleResolution": "node",
"sourceMap": true,
"outDir": "dist",
},
"lib": ["ESNext"],
}
希望它能解决你的问题!

我有同样的问题,并解决了它添加“es5”库tsconfig。Json是这样的:
{
"compilerOptions": {
"target": "es5", //defines what sort of code ts generates, es5 because it's what most browsers currently UNDERSTANDS.
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true, //for angular to be able to use metadata we specify in our components.
"experimentalDecorators": true, //angular needs decorators like @Component, @Injectable, etc.
"removeComments": false,
"noImplicitAny": false,
"lib": [
"es2016",
"dom",
"es5"
]
}
}
