What path do I use in yarn 2 with plug 'n play to access a specific file in a package?

Question

This path was working node_modules/webpack/bin/webpack.js in the following command in Yarn 1...

yarn --cwd packages/mypackage/ node --trace-deprecation node_modules/webpack/bin/webpack.js --env env=dev

I moved to Yarn 2 (berry) with plug 'n play (PNP) and Workspaces so there's not a node_modules folder (the module I need is stored a zip file at .yarn/cache/webpack-npm-5.64.0-a89fa9e176-9d32a61d98.zip. The file within the zip upzips to /node_modules/webpack/bin/webpack.js.

Here's what I tried, but I'm getting a path error, so have the path wrong still...

yarn workspace @myworkspace/mypackage node --trace-deprecation .yarn/plugins/@webpack-npm/bin/webpack.js --env env=dev

If there's a better way to do this that doesn't require writing out this whole path, I'm all for that too.

As stated by the Yarn Docs PnP is now the standard mode for package installation and should automatically create a .pnp.cjs file. You may have to add

require('./.pnp.cjs').setup();

to your script and/or run

node -r ./.pnp.cjs ./server.js
NODE_OPTIONS="--require $(pwd)/.pnp.cjs" node ./server.js

as stated in the docs.

Look here on how to access your zip file in a function. It should be as easy as require.resolve(webpack/bin/webpack.js)
