Problem building Brave on Mac

Hi,

I am trying to build Brave on my Mac (Sonoma) and I am running into problem in the npm run build release step.
Specifically, I am following the steps outlined in https://github.com/brave/brave-browser on a release-version of brave checked out and not altered in any way.

I ran into multiple problems with nodes modules not being installed correctly, which I was able to fix. Now, the problem is the following:

~/b/src/brave  ◈ v1.61.109 ±  npm run build release

> brave-core@1.61.109 build
> node ./build/commands/scripts/commands.js build

The list continues and throws the same type of error multiple times. Anyhow, a recurring thing is the following error type:

It seems that I need to configure webpack to handle *.tsx files. Anyhow, I cam unsure about WHERE to configure this (i.e. in which file) and to WHAT to set WHICH parameters.

Anyhow here who might shed some light on this one?

Thanks in advance!

Anyone here who has an idea?

@Mattches wanted to tag since this has been up a while with no replies. Hoping you can give to more info or ping someone who can. Thanks

We’ll see if we can get @clifton to take a look.
