Solve - Module not found: Can't resolve 'babel-loader' #

To solve the error "Module not found: Error: Can't resolve 'babel-loader'", make sure to install the babel-loader package by opening your terminal in your project's root directory and running the command npm install -D babel-loader and restart your development server.

Open your terminal in your project's root directory (where your package.json file is located) and run the following commands:

shell
# 👇️ with NPM npm install --save-dev babel-loader @babel/core @babel/preset-env webpack # 👇️ ONLY If you use TypeScript npm install --save-dev @types/babel__preset-env @types/babel__core @types/webpack # ---------------------------------------------- # 👇️ with YARN yarn add babel-loader @babel/core @babel/preset-env webpack --dev # 👇️ ONLY If you use TypeScript yarn add @types/babel__preset-env @types/babel__core @types/webpack --dev

The command will add the babel-loader package to the development dependencies of your project.

Refer to the "Usage" section of the official npm page for babel-loader for how to integrate it in your webpack config.

Make sure to restart your development server and your IDE if necessary. Your dev server won't pick up the changes until you stop it and re-run the npm start command.

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

shell
# 👇️ delete node_modules and package-lock.json rm -rf node_modules rm -f package-lock.json # 👇️ clean npm cache npm cache clean --force npm install
Make sure to restart your IDE and dev server if the error still persists. VSCode often glitches and a reboot solves things sometimes.

If you're still getting the "Module not found: Error: Can't resolve 'babel-loader'" error, open your package.json file and make sure it contains the babel-loader package in the devDependencies object.

package.json
{ // ... rest "devDependencies": { "babel-loader": "^8.2.4", "@babel/core": "^7.17.8", "@babel/preset-env": "^7.16.11", "webpack": "^5.71.0", // 👇️ Only if you use TypeScript "@types/babel__core": "^7.1.19", "@types/babel__preset-env": "^7.9.2", "@types/webpack": "^5.28.0", } }

The babel-loader module should NOT be globally installed or be in your project's dependencies, it should be in the devDependencies object in your package.json file.

You can try to manually add the lines and re-run npm install.

shell
npm install

Or install the latest version of the package:

shell
# 👇️ with NPM npm install --save-dev babel-loader@latest @babel/core@latest @babel/preset-env@latest webpack@latest # 👇️ ONLY If you use TypeScript npm install --save-dev @types/babel__preset-env@latest @types/babel__core@latest @types/webpack@latest
