Node 应用程序在生产中抛出错误，但在具有相同包的开发中却没有？

Question

I am trying to deploy my first node application to production server in a shared hosting platform but whenever I run the start script I get the following error message:

returncode: 1 stdout:

thechoicebox-backend@1.0.0 dev /home/ftijpnql/tcb

node server.js --scripts-prepend-node-path stderr: npm WARN lifecycle The node binary used for scripts is

/home/ftijpnql/nodevenv/tcb/14/bin/node but npm is using /opt/alt/alt-nodejs14/root/usr/bin/node itself. Use the --scripts-prepend-node-path option to include the path for the node binary npm was executed with. internal/modules/cjs/loader.js:905
throw err; ^

Although with same dependency and node version the project is running in my system.

package.json

{
  "name": "thechoicebox-backend",
  "version": "1.0.0",
  "engines": {
    "node": "14.7.0"
  },
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node dist/app.js",
    "dev": "nodemon server.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "bcrypt": "^5.0.1",
    "body-parser": "^1.19.0",
    "dotenv": "^10.0.0",
    "express": "^4.17.1",
    "http": "0.0.1-security",
    "jsonwebtoken": "^8.5.1",
    "multer": "^1.4.2",
    "mysql2": "^2.2.5",
    "sequelize": "^6.6.2"
  },
  "devDependencies": {
    "nodemon": "^2.0.7"
  }
}

My production node version is 14.xx not same as in package.json file as that was not present there.

Kindly help me out I am stuck !

Answer 1

I had a "similar" problem with Node when I was debugging and I wanted to change to dev using nodemon.

• Check your /dist folder
  • The /dist folder contains the minimized version of the source code.
  • The code present in the /dist folder is actually the code which is used on production web applications. Along with the minified code.
  • The /dist folder also comprises of all the compiled modules that may or may not be used with other systems.
  • The /dist folder also contains all those files which are required to run/build a module for use with other platforms- either directly in the browser, or in a system.
• And very Important:
  • Ideally, it is considered a good practice to clean the /dist folder before each build.

This definitely helped me. Hope this helps you too.

Answer 2

Something went wrong in the package installation

you can do for re-install:

rm -rf node_modules

then

npm install
