Failed to resolve entry for package "matrix-js-sdk"

[kfiven]

When trying to start a dev server or build app, my build system reports:

[commonjs--resolver] Failed to resolve entry for package "matrix-js-sdk". The package may have incorrect main/module/exports specified in its package.json.
error during build:
Error: Failed to resolve entry for package "matrix-js-sdk". The package may have incorrect main/module/exports specified in its package.json.

Can you specify in more detail how to reproduce this issue? because this is working fine for me!

[kfiven]

Clone https://github.com/cinnyapp/cinny/tree/dependabot/npm_and_yarn/matrix-js-sdk-23.0.0 and then

npm ci

npm start

@kfiven I think this could be related to https://github.com/matrix-org/matrix-js-sdk/issues/3015 – specifically, that matrix-js-sdk's package.json#browser is set to ./lib/browser-index.ts, which afaict is not an existent file.

I have steps in that issue for how I fixed this for create-react-app / Webpack 5; maybe they'd work for you as well?

This seems to also break vitejs:

  This error came from the "onResolve" callback registered here:
