How to fix “Cannot Find Module ‘semver'” Error on Ubuntu

If you have been running into the “cannot find module ‘semver'” error message, you have come to the right place.

This error is a common issue in Node.js applications and scripts that rely on the semver module.

Semver is short for “semantic versioning”. It is a library used to parse, validate, increment, as well as compare semantic version numbers.

Common Causes and Solutions

Module Not Installed

The error may be due to the semver module not being installed on your project or globally.

Solution: So, install the semver module using npm (Node Package Manager).

npm install semver

Incorrect Directory

Sometimes, the error may be due to us running the script from a directory where the semver module is not installed.

Solution: We have to make sure we are in the correct directory where our project and its dependencies are installed.

cd /path/to/your/project

Corrupted node_modules Folder

If the node_modules folder is corrupted or incomplete, it will lead to the error message.

Solution: So, try deleting the node_modules folder and reinstalling the dependencies.

rm -rf node_modules
npm install

Incorrect Import Path

There might be an issue with the way the semver module is imported in our code.

Solution: So, check the import statement in the code. It should look like this:

const semver = require('semver');

Troubleshooting Tips

1. First, check if semver is listed as a dependency in the `package.json` file.

   {
"dependencies": {
"semver": "^7.3.4"
}
}


   Also, if it’s missing, add it and run `npm install`.
2. Then, delete the `node_modules` folder and the `package-lock.json` file.

   rm -rf node_modules package-lock.json

   After that, reinstall dependencies:

   npm install
3. Also, if we need semver globally, install it using the `-g` flag.

   npm install -g semver
4. Then, make sure that the Node.js and npm versions are up to date.

   node -v
npm -v


   Update them if necessary.

By following the above steps, we will be able to resolve the “cannot find module ‘semver'” error and get your Node.js application running smoothly.
