Cannot find node-sass in Yarn workspace

[swansontec]

I am using Yarn workspaces, which allows several projects to live in the same Git repository and share a common node_modules folder:

node_modules/
package.json
packages/
  some-library/
    package.json
    rollup.config.js
  another-library/
    package.json
    rollup.config.js

When I try to run rollup within another-library, the rollup-plugin-postcss plugin complains that it cannot find packages/another-library/node_modules/node-scss, which doesn't exist. This is because the node_modules directory isn't inside another-library, but two levels up from us.

Possible Solutions

It looks like the localRequire function is to blame, since it is hard-coded to only look in the current working directory:

const localRequire = name => require(path.resolve('node_modules', name))

One solution might be to have localRequire fall back on normal require if there's an issue:

const localRequire = name => {
  try {
    return require(path.resolve('node_modules', name))
  } catch (e) {
    return require(name)
  }
}

This would be a quick & dirty fix. Otherwise, maybe just ditching localRequire and using normal require might work, on the grounds that rollup-plugin-postcss and node-sass should be installed to the same place anyhow. Another option is enhance localRequire using the node-resolve package, so it will accurately search for the node_modules directory starting in the current working directory.

Release 1.3.4 has the fix, so this is resolved now. Thanks a lot!
