部署到Azure Web应用后，某些模块不会自动安装

Question

After deploying to Azure Web apps, some modules are not automatically installed.

After deploying, the following error is output.

Error: Can not find module 'Cookie-parser'

At that time, I run 'npm install cookie-parser --save'.

In the package.json, the dependencies of the cookie-parser is surely saved.

{
  "name": "solo",
  "description": "demo",
  "version": "0.0.1",
  "private": true,
  "license": "MIT",
  "author": "lostsupervisor",
  "engines": {
     "node": ">=6.9.1"
  },
  "dependencies": {
     "body-parser": "^1.17.2",
     "cookie-parser": "^1.4.3",
     "ejs": "^2.5.6",
     "express": "^4.15.4",
     "express-session": "^1.15.4",
     "mssql": "^4.0.4",
     "tedious": "^2.0.0"
  },
  "scripts": {
     "start": "node index.js"
  } 
}

However, the same event occur after deploying next time.

Could you teach me a solution?

Answer 1

You are using Cookie-parser which is wrong.

In NPM modules while downloading npm upper and lower cases matter. Change it to cookie-parser , upper C is causing the problem.

Answer 2

It was caused by package-lock.json being not being pushed. I solved it by pushing it. Thank you very much.
