[0] Error [TransformError]: 
[0] You installed esbuild for another platform than the one you're currently using.
[0] This won't work because esbuild is written with native code and needs to
[0] install a platform-specific binary executable.
[0] 
[0] Specifically the "@esbuild/darwin-x64" package is present but this platform
[0] needs the "@esbuild/darwin-arm64" package instead. People often get into this
[0] situation by installing esbuild with npm running inside of Rosetta 2 and then
[0] trying to use it with node running outside of Rosetta 2, or vice versa (Rosetta
[0] 2 is Apple's on-the-fly x86_64-to-arm64 translation service).
[0] 
[0] If you are installing with npm, you can try ensuring that both npm and node are
[0] not running under Rosetta 2 and then reinstalling esbuild. This likely involves
[0] changing how you installed npm and/or node. For example, installing node with
[0] the universal installer here should work: https://nodejs.org/en/download/. Or
[0] you could consider using yarn instead of npm which has built-in support for
[0] installing a package on multiple platforms simultaneously.
[0] 
[0] If you are installing with yarn, you can try listing both "arm64" and "x64"
[0] in your ".yarnrc.yml" file using the "supportedArchitectures" feature:
[0] https://yarnpkg.com/configuration/yarnrc/#supportedArchitectures
[0] Keep in mind that this means multiple copies of esbuild will be present.
[0] 
[0] Another alternative is to use the "esbuild-wasm" package instead, which works
[0] the same way on all platforms. But it comes with a heavy performance cost and
[0] can sometimes be 10x slower than the "esbuild" package, so you may also not
[0] want to do that.

Did you run the commands npm update and npm upgrade before starting the platform ?

EDIT: According to your logs, please remove your node_modules and run npm install again

[chapuisk]

I did a npm prune and npm install and got a new error that runs in circles:

This error is because you do not have GAMA open next to the webplatform (based on the log, it's trying to connect to GAMA on 127.0.0.1:1000).

Please open GAMA on that same machine, check that GAMA Server is set on port 1000, and everything should work :)
