Estoy configurando una aplicación NodeJS + Mysql + Typescript + Docker, pero tengo un problema cuando trato de incluir el paquete mysql2 npm en mi script principal. De hecho, cada vez que incluyo el script me sale este error: Error TS2307: Cannot find module 'mysql2' or its corresponding type declarations. .

Aquí están mis archivos:

 // src/index.ts import 'dotenv/config'; import express, { Application, Request, Response } from 'express'; import mysql from 'mysql2'; const app: Application = express(); const pool = mysql.createPool({ host: process.env.MYSQL_HOST, user: process.env.MYSQL_USER, password: process.env.MYSQL_ROOT_PASSWORD, database: process.env.MYSQL_DATABASE, }); const db = pool.promise(); // App app.use(express.json()); app.get('/', async (_req: Request, res: Response) => { const results = await db.query('SELECT * FROM my_table'); [...] }); app.listen(process.env.NODE_LOCAL_PORT, () => { [...] });

 // package.json { "name": "my_app", "version": "0.0.1", "scripts": { "start": "nodemon" }, "dependencies": { "dotenv": "^10.0.0", "express": "^4.17.1", "mysql2": "^2.3.0", "nodemon": "^2.0.12", "typescript": "^4.3.5" }, "devDependencies": { "@types/express": "^4.17.13", "@types/node": "^16.4.13", "ts-node": "^10.2.0" } }

 // Dockerfile FROM node:latest WORKDIR /app/ COPY package.json yarn.lock ./ RUN yarn COPY . /

 // docker-compose.yaml version: "3.8" services: web: build: context: . env_file: ./.env command: yarn start volumes: - .:/app/ - /app/node_modules ports: - $NODE_LOCAL_PORT:$NODE_DOCKER_PORT depends_on: - mysql environment: MYSQL_HOST: mysql mysql: image: mysql env_file: ./.env environment: MYSQL_ROOT_PASSWORD: $MYSQL_ROOT_PASSWORD MYSQL_DATABASE: $MYSQL_DATABASE ports: - $MYSQL_LOCAL_PORT:$MYSQL_DOCKER_PORT volumes: - mysql:/var/lib/mysql - mysql_config:/etc/mysql volumes: mysql: mysql_config:

¿Alguna idea de por qué sigo teniendo este problema?
