gem 'rmagick', :require => false

I don't know whether it is a solution or not but it worked for me after removing gem "rmagick" from environment.rb file without breaking anything. This might because of gem already installed in system.

React Native Xcode errors

I use react native 0.65.1 and Xcode 10 to create a react native app.
I have changed the objectVersion in ios/project.xcodeproj/project.pbxproj and ios/Pods/Pods.xcodeproj/project.pbxproj from 54 to 51 so I can open the xcworkspace file in Xcode 10. Other than that I pretty much follow the instructions on react native website and didn't change anything.
When running
npx react-native run-ios
in the terminal, I get the following errors mainly (but not all) in the file "/node_modules/react-native/React/Views/RCTDatePickerManager.m":

file paths has been slightly modified for improved readability. Please kindly advice how to fix.
I had this exact problem, and the dispiriting experience of this being the only hit on google, with no response :D
For me, upgrading XCode fixed this. Everything was working locally as I'd recently upgraded XCode fully, but on Bitrise CI, I was getting the error. Bitrise lets you update XCode from the stacks tab.
I upgraded from 11.7 --> 12.4, and that resolved the issue.

ejabberd 16.06 is not compliant with Erlang OTP R19. You should use ejabberd 16.09.

warning: already initialized constant VERIFY_PEER

When I try to start the server I get the following warning:
/Users/sumitkalra1984/MVP/config/initializers/devise.rb:5: warning: already initialized constant VERIFY_PEER
My devise file:
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE if Rails.env.development?
How do I find where the constant is already defined, and how do I overwrite that definition?
While I cannot find where else the constant is initialized, you can silence the warning by wrapping that line in a silence_warnings block.
silence_warnings do
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE unless Rails.env.production?
end
See: http://api.rubyonrails.org/classes/Kernel.html#method-i-silence_warnings
You can invoke OpenSSL::SSL.send(:remove_const, :VERIFY_PEER) before to unset the constant, set it as you need it, and restore it to its original value afterwards. Here is example code from a gist:
prev_setting = OpenSSL::SSL.send(:remove_const, :VERIFY_PEER)
OpenSSL::SSL.const_set(:VERIFY_PEER, OpenSSL::SSL::VERIFY_NONE)
# HTTP requests with DISABLED certificate verification go here.
OpenSSL::SSL.send(:remove_const, :VERIFY_PEER)
OpenSSL::SSL.const_set(:VERIFY_PEER, prev_setting)
