Cannot find module '@babel/preset-env'

[lukaskoeller]

When I run the following command…

pnpm dlx vite-bundle-visualizer

…in the root of my vite project which is part of a pnpm monorepo, I get the following error:

[vite:legacy-post-process] Cannot find module '@babel/preset-env'

Workaround Solution

The main problem here is the @vitejs/plugin-legacy in the vite.config.ts. If you comment the import and its usage out or remove it, the command works fine.

It seems weird. Can you provide your monorepo directory structure and vite.config.ts? Or try use npx vite-bundle-visualizer?

[lukaskoeller]

@KusStar I had the same issue using npx.

The path to the vite app I tested my-monorepo/src/mf/my-app/vite.config.ts

And what's in package.json? What if your execute in my-monorepo and use -c point to src/mf/my-app/vite.config.ts？

# in my-monorepo
npx vite-bundle-visualizer -c src/mf/my-app/vite.config.ts

Running from the monorepo root and pointing to the vite.config of the app throws the following error:

Could not resolve entry module "index.html".

Your project structure is complex. Can you provide a reproduce repo?

Your project structure is complex. Can you provide a reproduce repo?

Sure. Here is a repro on Stackblitz: https://stackblitz.com/edit/vitejs-vite-mkjnwn?file=vite.config.ts

I literally just added the @vitejs/plugin-legacy package and adjusted vite.config.ts accordingly. It is the same reason it is failing in my app. The error though is a different one: [visualizer] recursive use of an object detected which would lead to unsafe aliasing in rust

[KusStar]

Seems like the rust error was caused in WebContainer?

On my local machine, it was fine

And by the way, @vitejs/plugin-legacy actually has problem to visualize bundle, i will try to find out why.
