I see this error when running npm start for the latest commit in the textbooks repo which changed studio dependency from 0.1.35 to 0.1.36.

node -v
v18.15.0

npm -v
9.5.0

I suspect that the bundleScripts method in assets.js (which is used as mgon-build) is not passing compiler options correctly.

I have also encountered a similar error. How can I solve it? Thank you!

@mougedashu I think this has been fixed in this commmit but studio package has not been published to npm yet.

For now, you can try replacing @mathigon/studio version 0.1.37 to @dhimath/studio version 0.1.38. But you will also have to replace all import statements in files like functions.ts to import ... from '@dhimath/studio';

@plegner If you could publish latest version of the studio package, that would be great. BTW, the docs/example shows this error:
