Error: Cannot find module 'process/browser.js'

[MichailShcherbakov]

Hi @davidmyersdev.

When I run yarn I get a waring

And when I try to build a lib vite throws an error

Link to Codesandbox

Can you help me to fix it?

Thank you!

I've got the same error

[manylovv]

I decided to try another version, and ^0.7.0 works just fine for me

[MichailShcherbakov]

@manylovv Unfortunately, I can't use 0.7.0 version in my project. I need "exclude" functionality.

It looks like the error is in "buffer-polyfill" in the package.json. Yarn possibly does not support it.

I don't know why the `shim.js' file is used here

const globalShimsPath = require.resolve('vite-plugin-node-polyfills/shims')

instead of using the helpers/esbuild/shim.js file from node-stdlib-browser

const globalShimsPath = require.resolve('node-stdlib-browser/helpers/esbuild/shim')

and for what this one

included[name] = globals.includes(name) ? globalShimsPath : value

I just changed all of it. And it works fine for me.

I've started looking into this, but I'm having trouble reproducing it locally.

[MichailShcherbakov]

@davidmyersdev I've attached a link to an example project. The error is reproduced when building or running project after yarn install.

Same here

[davidmyersdev]

I think I see what's happening now. It appears that Yarn v1 does not handle the aliased process dependency as it should, so it just skips it rather than unpack it into node_modules. I'll have to figure out how I want to handle this, but it shouldn't be too bad to get a fix together. To answer your earlier question, the replacement shims file is necessary because node-stdlib-browser has an out-of-date buffer dependency.

There also appears to be an open issue about this bug without any responses. https://github.com/yarnpkg/yarn/issues/6907

[davidmyersdev]

This is fixed in v0.11.3.
