Recently, I encountered some issues with my Node.js and npm setup on my macOS machine after updating the Node.js version from 20.11.1 to 20.12.0 using NVM (Node Version Manager). I wanted to share my experience and the steps I took to resolve these problems, hoping it might help others facing similar situations.
Issue 1: Permission Denied Error during nvm install-latest-npm
After switching to Node.js version 20.12.0 using nvm use --lts, I ran into a permission issue while trying to update npm to the latest version using nvm install-latest-npm. The error message looked like this:
$ nvm install-latest-npm
Attempting to upgrade to the latest working version of npm...
* Installing latest `npm`; if this does not work on your node version, please report a bug!

Solution
To resolve this permission issue, I used the following command to change the ownership of the /opt/homebrew/lib/node_modules directory to my user:
sudo chown -R anonymous /opt/homebrew/lib/node_modules
Replace anonymous with your own username.
Note: I also tried running sudo nvm install-latest-npm, but it threw an error saying that the nvm command was not found. It's better to change the directory ownership instead.
Issue 2: yarn start:dev Not Working after npm Update
After successfully updating npm, I encountered another problem where running yarn start:dev did not work as expected. I was using Yarn version 4 at the time.
Solution
To fix this issue, I ran the following command:
corepack enable
This command enables the Corepack feature, which is a tool for managing package manager versions. After enabling Corepack, yarn start:dev started working correctly.
Conclusion
Dealing with Node.js and npm issues can be frustrating at times, especially when updating versions, but it's important to understand the root cause of the problem and find the appropriate solution. In my case, the permission issue during nvm install-latest-npm was resolved by changing the ownership of the relevant directory. The yarn start:dev problem was fixed by enabling Corepack.
If you encounter similar issues after updating your Node.js version via NVM, I hope this blog post can provide some guidance and help you resolve them quickly. Remember to always read the error messages carefully and search for solutions specific to your setup.
Happy coding!
