Scss Postcss issues

Hi found an issue with the postcss compilation error whereby the devdepencies compute the prefix output of the perfix.css as below:

internal/process/esm_loader.js:74 internalBinding('errors').triggerUncaughtException(
^Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'postcss' imported from C:....s\node_modules\postcss-cli\index.js at packageResolve (internal/modules/esm/resolve.js:655:9) at moduleResolve (internal/modules/esm/resolve.js:696:18) at Loader.defaultResolve [as _resolve] (internal/modules/esm/resolve.js:810:11) at Loader.resolve (internal/modules/esm/loader.js:86:40) at Loader.getModuleJob (internal/modules/esm/loader.js:230:28) at ModuleWrap.

Exit status 1 npm ERR! npm ERR! Failed at the [email protected] prefix:css script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.`

Anyway, I found a simple solution to the problem:

1. Just update your node js to the latest version.
2. Reinstall autoprefixer after updating your node js application {npm install autoprefixer --save-dev}
3. Reinstall your postcss npm install postcss-cli --save-dev
4. Okay you will be ready to compile your Scss code. Hopefully, you will not face any issues compiling your output.
