CompileError: WebAssembly.instantiate(): invalid value type 'externref'

[gareia]

Hi, I couldn't find a similar issue, I'd really appreciate it if you could help me.

When running npm run dump I get the following error CompileError: WebAssembly.instantiate() invalid value type 'externref', enable with --experimental-wasm-reftypes @+166

I'm using Windows 10. Below is my package.json. I initially thought the issue might be related to the requirements.txt, but even just including Streamlit generates the same error. Additionally, it may be worth mentioning that my default browser was Brave but I changed it to Chrome, however, when opening a new terminal I kept encountering the same error. Thank you for your time.

Unfortunately I don't have access to Win10 env and can't reproduce the error now.

• What about deleting and reinstalling your node_modules directory? It has the pyodide subdir so refreshing it may help?
• Can you share your requirements.txt? If older versions of some packages, it may cause the problem like RuntimeError: abort(CompileError: WebAssembly.instantiate(): Compiling function #7019:"cvRodrigues2" failed: Invalid opcode 0xfe (enable with --experimental-wasm-threads) @+1580665) opencv/opencv#20697 ?

Hi, thank you for answering My requirements.txt:

streamlit
sqlalchemy
plotly
pyodbc

I got a new error related to pyodbc, it looks like it is not supported by pyodide :( By any chance, do you happen to know about it?
