Same issue getting me in my react app for package replace-in-file module, asking me add path-browserify in the same way as. You shown for process

[codecleric]

Worked for me -- the error message is pretty clear but I googled it anyway and your video came right up, super clutch -- thanks 😎

[dagi_works]

The issue for me was that vscode automatically imported a library while I was coding: "firestore" and it was causing a whole heap of errors, look out for any unused or unintentional imports.

Webpack 5 is a mess. No matter what solution you try to apply online, polyfills just dont work. Tried downgrading which seems fine initially unlless your code needs those node libs then everything throws. What were they thinking?

Not working with Native react / React-scripts :/

[marcoramos]

ins not working for me. How can I be sure that the webpack.config.js is been read?

[koyenapaul]

I have followed all the steps but still the error persists.
It is still showing:
ERROR in 4:15-32
Module not found: Error: Can't resolve 'crypto' in

Can anyone help please?

It doesn't work for me in Angular 12 by creating webpack.config.js and adding the fallback code.

[isratjahan]

Thanks a lot! its totally worked for me!

[iqbalhassan-dtdo]

module.exports = {
resolve: {
fallback: {
"util": require.resolve("util/"),
"path": require.resolve("path-browserify"),
"fs": false,
}
}
}
they install util and path-browserify but still give me error can you resolve this issues ?

[asleshka]

after fixing this issue got a lot of errors like that but with another modules like path-browserify. How to fix it?

[ayoabimbola]

Thanks for this video... I ran into a similar issue with node's Buffer API. I've tried almost all solutions online - including yours - but it's still not working. Code still says Buffer is not defined.

Thanks again

[HarishKurupnarayana]

Hi I did the same steps, and got the things resolved except one. Getting the following error:-
ERROR in 24:11-24
Module not found: Error: Can't resolve 'fs'

[cherifbarry]

I am getting the same error In angular and I performed this tutorial but it doesn't work😢

[webdev]

my vscode had imported unnecessary libraries automatically . which caused me this issue. after deleting this it worked properly.

[Konslufius]

Ok, were exactly are the parts that say "create an webpack.config.js file"?

[samuelefesoa]

Tried doing the same thing it isn't working for me.

[erickkisreal]

Tried the suggested solution where I make the fallback to false. making webpack.config.js file and adding where I set the "path" to false. Got the same error. I also tried doing npm run reject to see the actual webpack.config.js and added the statement there and it's not working

[wasalrasool]

http:false, or require it as you did but nothing is working what should i do now
