Failed to import mqtt module after upgrading react-scripts to 0.4.1

[alwint3r]

I was using mqtt module with react-scripts v0.2.3 to build some sort of IoT web app. Everything was fine until I upgraded the react-scripts to v0.4.1. There was an error from the developer console:

Uncaught Error: process.binding is not supported from browser.js at line 173.

Removing the import mqtt from 'mqtt' or require('mqtt') solve the issue, but that's not what I wanted. Any help would be appreciated. Thanks in advance!

I can’t reproduce this on master.

I’m going to release 0.4.2 today.
If you still have issues with it, please provide a project reproducing it.

Ok then, I'll re-open this issue if I still have the same problem with 0.4.2. Thanks!

[alwint3r]

I still have the same issue with 0.4.2, here's the project repo: https://github.com/alwint3r/reweather. You can checkout to 0.4.2 branch on that repo to check the error, since the master branch uses 0.3.1 and everything works fine.

The file that causes the error is src/lib/mqttredux.js.

I can't reproduce this on the 0.4.2 branch of that repo.

I also can’t reproduce this on 0.6.0 branch of that repo.
If it doesn’t work, please delete node_modules and run npm install.
Maybe some dependency is stale for some reason.

Thanks!

I did remove the node_modules and reinstall the dependencies but nothing changed. I still see nothing on the screen but the same error on the browser console.

By the way, I am going to try another alternatives since mqtt module is not my only option.
Thank you for your effort on this awesome tool!

I had the same problems with npm@2. The problem disappears with npm@3.
