The error message we’re encountering, “Module build failed: TypeError: this.getResolve is not a function at Object.loader”, typically occurs when there’s a mismatch between versions of node-sass, sass-loader, and webpack.

To fix this, we can try:

1. Ensure Compatibility:

Make sure we are using compatible versions of node-sass, sass-loader, and webpack. Sometimes, updating one package without updating the others can lead to compatibility issues.

2. Update Dependencies:

Update our project’s dependencies to their latest compatible versions. We can do this by running:

npm update

3. Specific Versions: If we’re experiencing issues with the latest versions, we can try installing specific versions known to work together.

For example we run

npm install sass-loader@^10.1.1 node-sass@^5.0.0

4. Clean Node Modules: Sometimes, conflicts arise due to corrupted or conflicting dependencies.

Try removing our node_modules folder and reinstalling dependencies:

rm -rf node_modules
npm install

5. Check webpack Configuration: Ensure that our webpack configuration is correctly set up to handle Sass files. Verify that sass-loader is configured properly in our webpack configuration file (usually webpack.config.js or vue.config.js if we’re using Vue CLI).

6. Fallback to Dart Sass: If we are using node-sass, consider switching to dart-sass as node-sass is deprecated.

Update our package.json to use sass instead of node-sass:

"sass": "^1.49.0",

And update our webpack or Vue configuration to use sass-loader with implementation option set to sass.

After trying these steps, rebuild your project to see if the error persists.

If it does, double-check your webpack configuration, and consider looking for any specific error messages that might provide more clues about the root cause of the issue.
