Describe the bug

npm start tries to open palemoon by default on Linux, even if it's not installed.

Starting the development server...

      throw er; // Unhandled 'error' event
      ^

hi @leonardopaffi
try npm cache clean --force
then delete your node_modules dir and package-lock.json file.
=> run npm install
then run npm start

@leonardopaffi please provide debug logs

eddiemonge · 2020-06-30T18:02:11Z

Is palemoon listed as your default browser? What happens if you do which palemoon?

leonardopaffi · 2020-07-01T07:14:17Z

@eddiemonge
I don't have palemoon installed, therefore which palemoon returns palemoon not found.

I encounter the same issue but with /usr/bin/firefox. After a while, I figure out that change the $BROWSER should fix the error. Give the path to your own browser. I use brave for example

export BROWSER=/usr/bin/brave
npm start

king-11 · 2020-11-13T16:52:01Z

@hieulw you are a life saver thanks a lot

Same was in my manjaro os with firefox, fixed it by export BROWSER=/usr/bin/firefox-developer-edition

ChARCOOL · 2020-12-28T13:30:03Z

It didn't happened to me before even after uninstalling Firefox, but It randomly just appeared in my console after trying to run start with yarn. I am currently using Microsoft Edge and I tried @hieulw method, and it worked pretty well. Thank you!

Exactly, that's because Manjaro comes pre-installed with Firefox by default and as default browser
