如何处理将打字稿编译为javascript的模块导入错误

Question

我开发了一些应用程序，当我尝试了

npm run start

发生附件错误。

似乎找不到模块bcrypt。

user.repository.js从ts编译为js

以下是导入bcrypt

const bcrypt = require("bcrypt");

在package.json，我安装了@types/bcrypt

"dependencies": {
    "@nestjs/common": "^7.0.0",
    "@nestjs/config": "^0.5.0",
    "@nestjs/core": "^7.0.0",
    "@nestjs/jwt": "^7.1.0",
    "@nestjs/passport": "^7.1.0",
    "@nestjs/platform-express": "^7.0.0",
    "@nestjs/typeorm": "^7.1.0",
    "@types/bcrypt": "^3.0.0",
    "@types/cookie-parser": "^1.4.2",
    "@types/joi": "^14.3.4",
    "class-transformer": "^0.3.1",
    "class-validator": "^0.12.2",
    "cookie-parser": "^1.4.5",
    "joi": "^17.2.0",
    "mysql": "^2.18.1",
    "passport": "^0.4.1",
    "passport-jwt": "^4.0.0",
    "pluralize": "^8.0.0",
    "reflect-metadata": "^0.1.13",
    "rimraf": "^3.0.2",
    "rxjs": "^6.5.4",
    "typeorm": "^0.2.25"

为什么会出错？？

如果有人有意见，请告诉我，谢谢。
