error message on installation

[cchorn]

I'm getting this error after using install command

/usr/bin/npm pack jupyterlab_voyager jupyterlab_voyager-0.1.0.tgz

Errored, use --debug for full output: TypeError: the JSON object must be str, not 'bytes'

Looks like it's some error with the JSON converting in this old version, we are wroking on a new version and will have a update soon. Meanwhile, if you want a try, you can use the test version published on npm: after install jupyterlab, use this command: jupyter labextension install jupyterlab_voyager_test

if installed correctly, you can then open csv, json, tsv file ,or notebook charts in Voyager through context menu. NOTE: you can't have both jupyterlab_voyager_test and jupyterlab_voyager installed at the same time, can only have one at a time

I tried jupyter labextension install jupyterlab_voyager_test but I now get this error FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Thanks @zzhangjii, I have been waiting for this extension to work with the latest Jupyter Lab and I got it to work with: jupyter labextension install jupyterlab_voyager_test

The install kept freezing but I fixed it by running the following command first: conda install nodejs

For the memory building error:

• export NODE_OPTIONS=--max-old-space-size=16000 or just add NODE_OPTIONS=--max-old-space-size=16000 env variable when running jupyter lab build

Ji, can you add this to the README?

Thanks for all the help! I will update the solutions in README!

Thank you. export NODE_OPTIONS=--max-old-space-size=16000 then jupyter labextension install jupyterlab_voyager_test also works inside a Docker container
