Can you explicitly list all the steps taken to get to this state?

[FTD-ZF]

New react-native project, version is "0.62.0 ", execute the command pod install in the ios directory, open the ios directory with xcode, compile, and report an error, is it the version of xcode? My xcode version is 10.1

Seems to be the same as react-native-community/upgrade-support#20.

After updating cocoapods to 1.9.1, it's working fine.

[lucasbento]

Awesome, thanks for reporting back @shukerullah!

Closing this as it's resolved.

For some reason my cocoapods do not update right.

What I did was:
sudo gem update --system
rvm install ruby (I use RVM to Ruby version management)

So I tried install cocoapods again

gem install cocoapods
pod --version
And get these message:
Could not find proper version of cocoapods (1.5.3) in any of the sources Runbundle installto install missing gems.
After run this bundle install
I finally run
bundle update cocoapods
And get this done
