Answer №1

Encountering errors like this can be frustrating, but I found a solution that worked for me.

To resolve the issue:

Remove the node_modules directory by running: rm -rf node_modules

Next, clear the npm cache forcefully with:

npm cache clean --force

Then, delete the package_lock.json file.

Finally, run:

npm install

I hope these steps help you resolve the error as they did for me.
