Facing several errors using npm

Question

I first tried installing React using create-react-app, and at that time, it showed me some warnings. I ignored them at that time and started working on my project. Then, recently I tried to deploy my react app to github pages, and was facing errors again!

First, I got:

new MiniCssExtractPlugin({
^


MiniCssExtractPlugin is not a constructor

I used this: npm i -D --save-exact [email protected] to change the version and got away with the error, but when running npm run deploy again, I got this error:

Creating an optimized production build...
Failed to compile.

The target environment doesn't support dynamic import() syntax so it's not possible to use 
external type 'module' within a script

I don't understand what this really means and it also doesn't show any line reference from which the error was causing.

Well, after that, I thought that something was wrong with my project and tried to start another react project. I used npx create-react-app react-deploy to see if this app would deploy to github pages. But, it didn't install and showed me this:

I'm farely new to React and Node.js/npm and now, I'm really frustrated due to all of these errors. My node version is 16.13.0 and npm's: 8.1.0

Should I install the older version of node from scratch or not?
