RN 0.74 adds deprecated yarn-1.22.22.cjs #385

Closed hristo87 closed 5 months ago

Bug

In the latest React Native update (version 0.74), the documentation indicates a transition to Yarn 3.x for new projects (as seen in the attached image). However, upon using the helper, a yarn-1.22.22.cjs file is added, and the .yarnrc file points to this file. Given that the documentation explicitly states the deprecation of Yarn 1.x in favor of 3.x, is this inclusion of the yarn-1.22.22.cjs file expected? Additionally, the file was not present initially but was added at a later time. Could you provide clarity on this discrepancy?

hey @hristo87! yes, you're right. There was a regression that in some scenario CLI didn't bump Yarn to 3.x → it's already addressed and will be released with React Native 0.74.1.

Thank you for clarifying this!
