Module Parse Error in WorkerJob Class: Unexpected Token in @loaders.gl/worker-utils

[DanielLanghann]

Describe the bug When i run yarn start i got among others this error:

ERROR in ./node_modules/@loaders.gl/worker-utils/dist/lib/worker-farm/worker-job.js 9:8
Module parse failed: Unexpected token (9:8)
File was processed with these loaders:
 * ../../node_modules/source-map-loader/dist/cjs.js
 * ../../node_modules/source-map-loader/dist/cjs.js
You may need an additional loader to handle the result of these loaders.

｢wdm｣: Failed to compile.

I attached the entire list of errors:

stack_trace_kepler.txt

To Reproduce Steps to reproduce the behavior:

I work on MacOS (14.4.1). and use Node: v18.18.2 (I also tried newer versions)

1. I fork the repository (and did no changes).
2. Run: yarn global add puppeteer
3. Run: yarn bootstrap
4. Run: export MapboxAccessToken=<insert_my_token>
5. Run: yarn start Now i got the attached Error Trace.

Additional context Can anyone give me a hint on how to get Kepler running locally? I tried working through the errors one by one, but no matter what I did, I kept having compatibility issues and was unable (for the past two days) to run the app. We also tried running the steps on an Ubuntu machine and launching the app in Docker. Also tried newer Versions of Node. Thank you in advance for your feedback. WR Daniel

@igorDykhta Could it be yarn version issue?

[igorDykhta]

I'll check. I have a different issue on my side, but related to loaders.gl as well. The fork works with the same yarn version.

@ibgreen i see that there is a special rule added by @lixun910 for @probe.gl in kepler.gl-jupyter

// for compiling @probe.gl, website build started to fail (March, 2024)
  {
    test: /\.(js|ts)$/,
    loader: 'babel-loader',
    include: [
      /node_modules\/@probe.gl/,
      /node_modules\/@loaders.gl/,
      /node_modules\/@math.gl/
    ]
  }

Thanks, Igor! I remember I added this one for kepler-jupyter build, and it should not impact kepler build?

[igorDykhta]

@DanielLanghann Could you try running igr/fix-yarn-start branch? I can't reproduce the exact error, but maybe the fix is similar to probe.gl fix.

[DanielLanghann]

@igorDykhta Could it be yarn version issue?

I'm using yarn 1.22.19 on my machine.

[DanielLanghann]

@DanielLanghann Could you try running igr/fix-yarn-start branch? I can't reproduce the exact error, but maybe the fix is similar to probe.gl fix.

@igorDykhta First, thank you for your help! I cloned the repository to have a fresh start, switched to branch igr/fix-yarn-startand run yarn global add puppeteer, yarn bootstrap, export MapboxAccessToken=<my_token> and yarn start. The last success message in the build process is success Saved lockfile. After a few warnings (almost) related to @loaders.gl I got many errors also related to @loaders.gl. Most errors are "Module parse failed: Unexpected token" errors. I'm not a Java Script Pro, but for me it seems that the current build setup is not able to parse or transpile correctly or handling the syntax of used java script features.

Same here

Hi, i've also tried to get this repo running locally somehow but always failed so far.

I've checked out igr/fix-yarn-start then yarn dlx puppeteer and yarn bootstrap which results in

I'am using stable yarn (4.3.1) by default but also tried with yarn 3.8.3 and 1.22.22 (yarn classic) with the same result.

@Devidian, this looks like a separate issue.

@DanielLanghann I have a fix. But I need to polish it a bit. Wll public PR soon.

[ibgreen]

I am willing to take a look if there are loaders.gl specific issues. However @heshan0131 is in the process of modernizing the entire kepler build system so let's make sure we frame any bugs against the latest setups.

[mars-dlx]

@Devidian I could reproduce it in WSL.

You need to install missed GL dependencies https://github.com/stackgl/headless-gl?tab=readme-ov-file#system-dependencies

[alcy]

@mars-dlx I tried your "fix-webpack-builds" branch directly and at least for the demo-app which I had been trying to run so far (with the errors like @DanielLanghann was seeing) - it worked wonderfully. Thanks! :)
