Amazing! Thanks so much!

Sir, you deserve a diamond medal of honour. Thanks forever!

I wish I could buy you a Beer. Thanks a lot.

It didn't work for me. Not sure what went wrong honestly, but following this manual instructions worked: https://stackoverflow.com/questions/11177954/how-do-i-completely-uninstall-node-js-and-reinstall-from-beginning-mac-os-x

You save my mind! Thanks

Thank you, amazing!

This script is awesome!
Could you please update it to most up-to-date node version? or maybe with a line asking for desired version?
Thanks!

@Moondancer83 See the repo for some of those updates: https://github.com/brock/node-reinstall

This script definitely is battle-tested!

Thanks! It saved my day.

PS: I use Linux Mint Tessa.

This didn't install it for macOS zsh (which is default now)

This is awesome. I had almost given up. Thanks!

Incredible work. Thank you!

You're a legend. I ran into an issue with AWS SAM, and this was the solution that fixed it.

@david-rodriguez I've not updated this in a long time, so it is still using a default Node.js version from 2014. Be sure to install a newer version of node before you get started! Something like nvm install 16

@brock I tweaked the script before running it to install the latest version of node. Nonetheless, you did most of the heavy lifting.

Working perfectly on 1 Aug'23. Thanks a ton.

Two small suggestions:

• /usr/local/share/doc/node and /usrl/local/share/systemtap/tapset/node.stp are not cleaned up.
• update installation steps as shown on nvm-sh/nvm

@seguri Thanks for posting the feedback on this script.

Can you share more info on what installer uses each of these install paths? I don't like adding directory deletions without vetting them to some degree in case someone blindly runs my scripts.

• /usr/local/share/doc/node
• /usr/local/share/systemtap/tapset/node.stp

And what needs to be updated to the installation steps from nvm-sh/nvm? I'm not up to date on their changes since they move a lot more than I do.

I don't typically update this Gist, but I do make updates to the node-reinstall repo when major changes need to happen, and would be happy to bring it up to date if it makes sense.

Replying here is fine, but if you're familiar with git and Github and want to create a Pull Request with the proposed changes, I'd happily review it and add you to the contributors.
