React Router Lessons - I get Errors when I "npm start"

Hi!
This is what I’m working on right now: React Router

I have done like the video lesson and followed the updated information about react dom v5 but I get Errors when I try to move on :woman_shrugging:

Am I doing something wrong here?

Starting the development server...

Hello!

What version of NodeJS are you using? You can check this by running node --version in a terminal.

Hi!
Sorry that I missed your comment!
I just solved it by uninstall the newest version of node and instead installed the LTS version :grinning:

For anyone not wishing to rollback to a previous node version:

In your package.json: change this line

"start": "react-scripts start"

to

"start": "react-scripts --openssl-legacy-provider start"

NOTE: This will introduce security issues. Only do this for the purpose of continuing with this exercise

Hi! Can you tell me please what command did you use to uninstall the newest version of node? I’m having the same problem

This problem seems to persist because the same thing happened to me. I didn’t have to change my node version, however, running export NODE_OPTIONS=–openssl-legacy-provider was enough.
