You can spot the problem by simply creating a new project with react-native init, and then checking it with yarn check.

yarn check v1.5.1
warning "sane#fsevents#node-pre-gyp@^0.6.39" could be deduped from "0.6.39" to "[email protected]"
error "metro#@babel/plugin-check-constants#@babel/[email protected]" doesn't satisfy found match of "@babel/[email protected]"
error An unexpected error occurred: "Found 1 errors.".

We've locked the version down today. It may be a few days and after that I expect stability around this issue. Should have done it sooner. Hope the situation improves. If the issue comes back after that please re-open this issue.

@rafeca this can be closed.

Hello @rafeca @pvdz,

With v0.48.1, there is a peer dependency with @babel/[email protected]. Our application is in the midst of upgrading to babel7. Is it possible to not have this peer dep?

[rafeca]

Hi!

Thanks for the heads up here! babel-beta.38 is being installed due to babel-preset-fbjs. It seems that with babel@7 stable @babel/plugin-check-constants is not needed anymore so we're going to remove it from the corresponding package 😄

@rafeca Thank you 🙂, this will be one of the last two TODOs before we can merge our babel7 upgrade. Any chance that we could get this peer dep removed this week, appreciate it!

Is the problem solved? I still got the warning when running yarn check.
