英文:
Can not import local module
问题
我正在尝试在一个Node.js应用程序中导入一个本地模块，但似乎无法成功。
modules/date.js：
const getDate = () => {...};const getDay = () => {...};export {getDate, getDay};
app.ts：
import {getDay, getDate} from "/modules/date";//import {getDay, getDate} from "/modules/date.js"; 也不起作用
错误信息：
找不到模块'/modules/date'或其对应的类型声明.ts(2307)
配置文件
package.json：
{"dependencies": {"ejs": "^3.1.8","express": "^4.18.2","mongoose": "^6.8.3","nodemon": "^2.0.20","typescript": "^4.9.4"},"name": "todolist","version": "1.0.0","description": "A simple todo list","main": "app.js","scripts": {"test": "echo \"Error: no test specified\" && exit 1"},"author": "Infinite Learner","license": "ISC","devDependencies": {"@types/express": "^4.17.15"},"type": "module"}
tsconfig.json：
{"compilerOptions": {"target": "es2016","lib": ["es6"],"moduleResolution": "node","rootDir": "./","outDir": "build","esModuleInterop": true,"forceConsistentCasingInFileNames": true,"strict": true,"skipLibCheck": true}}
你知道我缺少什么吗？
谢谢。
英文:
I am trying to import a local module on a node.js application and I do not seem to be able to.
modules/date.js :
const getDate = () => {...};const getDay = () => {...};export {getDate, getDay};
app.ts :
import {getDay, getDate} from "/modules/date";//import {getDay, getDate} from "/modules/date.js"; doesn't work either
The error :
Cannot find module '/modules/date' or its corresponding type declarations.ts(2307)
Config files

tsconfig.json:

Do you know what I am missing ?
Thank you.

因为你正在尝试将一个Js文件导入到一个Ts文件中，要么你将其更改为date.ts，要么在tsconfig.json中添加一些设置，也许可以查看这个链接：https://stackoverflow.com/questions/54320967/nodejs-how-to-import-js-file-into-typescript
