Currents is not working with yarn 3

[adrienharnay]

Hello,

I just upgraded a project from Yarn 1 to Yarn 3 (without Plug'n'Play), and now Currents is not able to find cypress.

Error: Cannot detect cypress. Is cypress installed?

I see the code relies on npm-which, which has not been updated for 6 years. When logging into getStateModulePath in cy2/lib/patch.js, here is the result of the candidates variable:

[
  '/private/var/folders/kb/0ht5tzkd6knbz4wn7nfpnfwh0000gn/T/xfs-91d8a950/node_modules/cypress/lib/tasks/state.js',
  '/private/var/folders/kb/0ht5tzkd6knbz4wn7nfpnfwh0000gn/T/lib/tasks/state.js',
  '/private/var/folders/kb/0ht5tzkd6knbz4wn7nfpnfwh0000gn/T/cypress/lib/tasks/state.js'
]

Do you think the logic could be updated to support Yarn 3 as more and more people are migrating to it?

Thanks in advance and have a nice evening

Hi @agoldis, thanks a lot! I confirm the new version works with Yarn 3.
