Unable to compile pyodide using webpack and typescript

🐛 Bug

When I’m trying to use pyodide in typescript project I’m getting bunch of errors during compilation:

• error-stack-parser does not export StackFrame from ErrorStackParser in version 2.0.7 which is currently installed with pyodide. It has been fixed in 2.1.0 so I’m assuming that updating version will fix this issue.

ERROR in ../../node_modules/pyodide/error_handling.gen.ts 193:49-59
TS2694: Namespace 'ErrorStackParser' has no exported member 'StackFrame'.
    191 | Tests.convertCppException = convertCppException;
    192 |
    193 | function isPyodideFrame(frame: ErrorStackParser.StackFrame): boolean {
        |                                                 ^^^^^^^^^^
    194 |   const fileName = frame.fileName || "";
    195 |   if (fileName.includes("pyodide.asm")) {
    196 |     return true;

• if it comes to three below errors I’m not sure what is the reason

To Reproduce

Please use following repository. Errors related to ErrorStackParser are not showing using this project (I installed newer version) however is still should be fixed.

Expected behavior

Pyodide package is compiling.

Environment

• Pyodide Version: 0.20.0
• Browser version: N/A
• Any other relevant information:

Additional context

It’s been an ongoing issue for us that we don’t have any developers with much JavaScript/webpack expertise.

Huh I don’t know which commit would have fixed this but that’s good news. Maybe we can reenable the webpack test
