Every time I run 'npm start' in the terminal, I get an error and the page won't load. How can I fix this?

Here is the error that I keep getting and I have the latest version of VSCode, plus I've installed all of the dependancies. ... Starting the development server...

Hey there Devontay Cross ! :wave:

I'm unable to replicate this issue which makes me thinks it has something to do with a node version issue possibly.

First, please ensure you've changed directories in your terminal to the correct folder

practice-state-in-react/1-introducing-the-practice/BEGIN/practice-state

then run the commands

npm i
npm start

If you still encounter the same issue, I'm curious as to what version of Node you're using. If you type

node -v

in your terminal, what does it read?

I saw something online that it may be related to a Node.js and the OpenSSL library used by Webpack issue. We could try the following commands as a potential work-around, I'm not sure if this would work or not but may be worth a shot...

npm i webpack@latest
rm -rf node_modules
npm i
npm start

Things still ran on my end after trying these, but I'm not having the initial issue that you are so I can't be certain.

If you need to undo those last commands and don't want to delete the project files / redownload them you can run

npm uninstall webpack
rm -rf node_modules
npm i

to get back where you were before doing so.

Finally found the solution to the problem, I needed to update node and run a auditfix --force to get everything working properly. Thanks for the help!
