Cannot import module @cortex-js/compute-engine

[edward1127]

Does anyone know how I can import module @cortex-js/compute-engine?

I get a module not found error when importing that module.

javascript.errors.JavaScriptError: ('require', "Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@cortex-js/compute-engine' imported from /home/edward/anaconda3/envs/arete/lib/python3.11/site-packages/javascript/js/deps.js\n    at new NodeError (node:internal/errors:399:5)\n    at packageResolve (node:internal/modules/esm/resolve:783:9)\n

Seems to work ok for me

If nessesary, you can use the CLI tool to manually install the package with

python -m javascript --install @cortex-js/compute-engine

thanks for replying. Yep, I confirmed that it works when using it independently. Then, it seems like this package and Django are not compatible.

django==4.2
djangorestframework==3.14.0

There does seem to be a minor issue with ESM path resolution, potentially fixed in #115. But with or without Django, I don't notice any issues.

I believe if you start the Django server, you will see the error. I think it might have something to do with how Django handles the import path.

python manage.py runserver

What is the Python code that triggered this error?

[edward1127]

Here's the code

from javascript import require
test = require('@cortex-js/compute-engine')

Can you link to a notebook that reproduces the error?

[edward1127]

pip install -r requirements.txt python manage.py runserver

running directly in sandbox will fail, so you might need to reproduce it by cloning the code into your local and run the commands above.
