Module not found, searching in an incorrect directory

After installing nodemon globally with the command npm i -g nodemon, it was installed in the global path:

C:\Users\John\AppData\Roaming

I then initiated a new project using npm init -y and created an index.js entry point with the following content:

{
  "name": "scp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node index.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.17.1",
    "jsonwebtoken": "^8.5.1"
  }
}

However, when I tried starting the app using nodemon, I encountered the error message:

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\nodemon\bin\nodemon.js'

Realizing that the path is incorrect, I attempted to reset it by running:

npm config set prefix C:\Users\John\AppData\Roaming
npm config get prefix

This returned:

C:\Users\John\AppData\Roaming

Despite this adjustment, the same error persisted when trying to start the app using nodemon:

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\nodemon\bin\nodemon.js'

How can I resolve this issue?

Answer №1

Would you be willing to give nodemon a shot by incorporating it into your existing package.json file using the following command:

npm install --save nodemon

Afterwards, update your start script to:

"start": "nodemon index.js"

Keep your fingers crossed and hopefully this solution will do the trick for you.

Answer №2

Encountering a similar error can occur when using the "&" symbol in a path name. While npm will install packages correctly in the 'foobar&foobar/myApp/node_modules' folder, the file paths to some packages will be incorrect. To resolve this issue, simply rename the folder containing the "&" symbol (foobar&foobar --> foobarAndfoobar) and then execute the following commands where your node_modules are located:

rm -rf node_modules
npm install

This solution should help alleviate any frustration for others facing the same problem.

Answer №3

To streamline your development process, consider adding nodemon as a dev dependency and specifying it in the scripts section of your project's package.json. This alleviates the need to install it globally whenever it's required.

For example, in your package.json:

 "scripts": {
    "start": "nodemon index.js"
  },

Regarding your original issue... The problem may stem from the configuration of your npm/node setup. It is recommended to utilize tools like NVM which manage multiple instances and configurations locally. This practice is highly recommended for any developer working with node applications.

Take a look at NVM here: https://github.com/coreybutler/nvm-windows Try using a local version of npm to troubleshoot the source of the issue. Keep in mind that conflicts may arise between your global node installation and NVM (such as bin paths), so consider exclusively using npm/nodes from NVM and removing the global one.

Answer №4

Make sure to review all your folders for any occurrences of "&". Change the name and nodemon should function properly. I spent an hour and a half troubleshooting this issue.
