我尝试通过打字稿初始化数据库。
我的 ts 是这样的:
import { User, UserRole } from '../entity/User';
import crypto from 'crypto';
import {dbManager, pwhash } from '..';
async function inituser()
{
const user = new User();
user.email = '[email protected]';
user.own_organization = []
user.salt = crypto.randomBytes(16).toString('hex');
user.password = pwhash("password", user.salt);
user.role = UserRole.admin;
await dbManager.save(user);
const duser = await dbManager.findOne(User);
return duser;
}
const duser = inituser();
console.log("Loaded users: ", duser);
当我尝试通过 ts-node 运行脚本时:
npx ts-node db/initializers/inituser.ts
有错误:

我在 package.json 文件中添加“类型”:“模块”。
{
"name": "typescript-test",
"version": "1.0.0",
"type": "module",
...
}
克服
的错误(node:3854) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
错误
Warning: To load an ES module, set "type": "module" in the package.json or
是由ts-node中的以下错误引起的:https://github.com/TypeStrong/ts-node/issues/935
Bug已关闭,有解决方案,但仍然开放:https://github.com/TypeStrong/ts-node/issues/1007
我不需要
"type": "module"
在package.json
.
在
tsconfig.json
中,我使用的是"module": "commonjs"
而不是"module": "es6",
。
我注意到这是技术债务未决,ts-node 问题 #1007 已解决。
当 ts-node 在项目中运行时,它使用本地的 tsconfig.json,通常不会设置为执行构建。
但是您可以添加一个专门用于 ts-node 的部分,覆盖这些设置。告诉它为 esm 构建对我有用:
{
"compilerOptions": {
...
},
"ts-node": {
"esm": true,
"compilerOptions": {
"module": "nodenext",
}
}
}
也许这有帮助:
node --no-warnings --loader ts-node/esm file.ts
只需添加
-O '{\"module\": \"commonjs\"}'
:
npx ts-node -O '{\"module\": \"commonjs\"}' db/initializers/inituser.ts
而且不需要在package.json中设置
"type": "module"
