Cuando ejecuto npm start o incluso pm2 start npm --name "app name" -- start , mi aplicación devuelve un error como este:

 /home/cloud/sites/myapp$ npm start > myapp@1.0.0 start /home/cloud/sites/myapp > node server.js internal/modules/cjs/loader.js:818 throw err; ^ Error: Cannot find module 'Cors' Require stack: - /home/cloud/sites/myapp/server.js at Function.Module._resolveFilename (internal/modules/cjs/loader.js:815:15) at Function.Module._load (internal/modules/cjs/loader.js:667:27) at Module.require (internal/modules/cjs/loader.js:887:19) at require (internal/modules/cjs/helpers.js:74:18) at Object.<anonymous> (/home/cloud/sites/myapp/server.js:2:14) at Module._compile (internal/modules/cjs/loader.js:999:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1027:10) at Module.load (internal/modules/cjs/loader.js:863:32) at Function.Module._load (internal/modules/cjs/loader.js:708:14) at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:60:12) { code: 'MODULE_NOT_FOUND', requireStack: [ '/home/cloud/sites/myapp/server.js' ] } npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! myapp@1.0.0 start: `node server.js` npm ERR!

Este es mi paquete.json:

 { "name": "myapp", "version": "1.0.0", "description": "* TEST\r * Login validation", "main": "server.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "node server.js" }, "dependencies": { "bcryptjs": "^2.4.3", "body-parser": "^1.19.0", "cors": "^2.8.5", "crypto-random-string": "^3.3.1", "express": "^4.17.1", "is-empty": "^1.2.0", "jsonwebtoken": "^8.5.1", "mongoose": "^5.11.17", "socket.io": "^4.0.1", "validator": "^13.5.2" } }

Y mi árbol de directorios:

 -myapp -config -node_modules -routes -utils -validation -package.json -package-lock.json -server.js

Intenté eliminar package-lock.json y node_modules y luego npm install nuevamente, incluso probé npm install cors , siempre se instala bien pero el error sigue siendo el mismo. ¿Algunas ideas?
