比如我在Home.vue组件里要使用全局变量isDev与全局方法log()<template>...</template>import { Options, Vue } from 'vue-class-component'@Options({})export default class Home extends Vue { created() { console.log(isDev) log('Home', 'test', 123) }}</script>然后又在根目录的global.d.ts(其中无import、export)里声明// Api返回结果declare interface Result<T = unknown> { code: 200 | 401 | 404 | 500 | 501 | 502 | number | any msg: string data: T}// 日志记录declare function log(tag: string, ...args: any[]): void//declare const isDev: boolean//declare const printLog: booleaninterface Window { isDev: boolean printLog: boolean log(tag: string, ...args: any[]): void}interface globalThis { isDev: boolean printLog: boolean log(tag: string, ...args: any[]): void}它却报错14:17 error 'isDev' is not defined no-undef15:5 error 'log' is not defined no-undef但是我在其他ts文件中可以直接使用
