Can't get it to run on arm64 (apple m1)

[compojoom]

If someone tries to execute:

yarn global add @raiden_network/raiden-cli

on an apple M1 machine the command fails with:

error ~/.config/yarn/global/node_modules/wrtc: Command failed.

the problem is obviously with the wrtc package. I looked at it and it seems that there hasn't been a new update since January 2021 and that's why there is no binary for arm64. I stumbled across this issue:
node-webrtc/node-webrtc#698

And it turns out that there are user forks that have corrected that problem. In this comment: node-webrtc/node-webrtc#698 (comment) a user even published a new package that contains the necessary binaries.

So, I decided to test if this package will fix the problem. I cloned the repo and changed the wrtc dependency in raiden-cli and raiden-ts to "@koush/wrtc": "^0.5.3",

Afterwards I tried to install. Now the wrtc error was gone, but I got a similar error with the canvas library. Luckily there the community seems to have new releases - they don't have a release with the binaries, but building from source worked after I installed the following dependencies:

brew install pkg-config cairo pango libpng jpeg giflib librsvg

source: Automattic/node-canvas#1733

Now I had to change the require('wrtc') in raiden-cli/src/index.ts to require('@koush/wrtc'). Then I followed the steps in the raiden-cli readme:

yarn install
yarn workspace raiden-ts build # build local dependency
yarn workspace @raiden_network/raiden-cli build # build the dependent output
yarn workspace @raiden_network/raiden-cli build:bundle # build the bundled output

Everything went fine. I tried to to execute the ./raiden command, but was confronted with:

➜ ./raiden --help
node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module '.'

  code: 'MODULE_NOT_FOUND',
  requireStack: [ '~/Development/light-client/raiden-cli/raiden' ]
}

No idea why that happens, but I was able to go around that by modifying the raiden file and just using require('bundle'). After that I was able to run the raiden command.

I'm not advising switching to the fork, but posting this here in case anyone else runs into the issue. And maybe the raiden team could think on a better solution to the problem.

@netcriptus Do you have a M1 machine? If not can you try this out on maybe @DinaBB machine in the office? I asked @karlb to support in debugging this tomorrow so would be good if you can collaborate on this.

[netcriptus]

No, mine is an Intel i5

[compojoom]

So the module not found error was resolved by downgrading inquirer:
#3150

The wrtc problem remains. As pointed out above I'm able to run the code by switching wrtc to @koush/wrtc

[taleldayekh]

@compojoom @andrevmatos Is this still relevant or can I close?

[andrevmatos]

It's still relevant. We'll be checking for options on providing wrtc library for M1 macs or replacing the library (the API is standardised) and how to ensure a seamless cross-platform experience.

Fixed in latest releases (linked above).
