Question

我正在尝试使用OvernightJS的Typescript，并且在尝试将类导入控制器中时遇到问题，出现错误提示：

错误：找不到模块'@ Models / company'

以某种方式，当我将导入更改为“ ../models/company”时，它可以工作。同样，导入“ @ Models / firebase”也可以。

UserController：

import { Controller, Get } from '@overnightjs/core'
import { Request, Response } from 'express'
import CompanyModel from '@Models/company'

@Controller('api/company')
export class CompanyController {
  private readonly company = new CompanyModel()

  @Get()
  private async get(req: Request, res: Response): Promise<any> {
    const companies = await this.company.getAllCompanies()

    return res.status(200).json({
      data: {
        companies
      }
    })
  }
}

CompanyModelClass：

import * as firebaseAdmin from 'firebase-admin'
import { Firestore, QuerySnapshot, QueryDocumentSnapshot } from '@Models/firebase'

class CompanyModel {
  private readonly firestore: Firestore

  constructor () {
    this.firestore = firebaseAdmin.firestore()
  }

  async getAllCompanies() {
    return await new Promise((resolve: any) => {
      this.firestore.collection('/companies').onSnapshot((snapshot: QuerySnapshot) => {
        const docs = snapshot.docs.map((doc: QueryDocumentSnapshot) => {
          return doc.data()
        })

        resolve(docs)
      })
    })
  }
}

export default CompanyModel

tsconfig：

将tsconfig-paths添加到运行脚本中后，问题解决了：

"dev": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' --exec 'ts-node' -r tsconfig-paths/register src/index.ts"
