does codesandbox use npm install or yarn add?

[wolverineks]

im getting a weird error, and it might be due to some differences in npm/yarn

Could not find module in path: 'readable-stream/errors' relative to '/node_modules/readable-stream/lib/internal/streams/state.js'

there might be some selective versioning going on, im not sure yet

[garethx]

Please provide an URL to a sandbox with this issue. Thanks.
