'Issues Running react project, SEVERAL module not found errors
so I'm trying to run this one react project (one that I've run SEVERAL times & has worked SEVERAL TIMES before), but for some reason, it just doesn't work and just won't give me a break. I'm struggling to see why I'm getting such a ridiculous amount of errors. I have the most up to date npm version installed I run 'npm install' command prior. Please help me out if you can. Thank you.

Solution 1:[1]
I faced the same problem and installed two libs
then it works.
Solution 2:[2]
This is React's not-so-subtle way of telling people to stop using back-end packages in their front-end applications. They have removed the default poly-fill for Nodejs packages. Read more about the current state here.
