Vitejs Error

Following all the install instructions (I've checked and re-checked 10 times at least). I get the following error running ....

mix assets.build

build
tsc && vite build

vite v7.1.12 building for production...

error during build:
[vite]: Rollup failed to resolve import "react" from "/Users/nutheory/code/ex_chemists/deps/live_react/assets/js/live_react/hooks.js".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
build.rollupOptions.external

... and if i try to run the app in the browser i get a similar vite error except it complains about "import 'react-dom/client'"...

everything looks right in deps and node_modules as far as i can see??? any ideas?

Reproduce the failure with mix assets.build and inspect the import from deps/live_react/assets/js/live_react/hooks.js, along with the Vite installation under assets/node_modules. Check why react and react-dom/client cannot be resolved; done means the asset build succeeds and the browser no longer reports these Vite import errors.
