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。

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)

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
