config.gem: Unpacked gem ….. in vendor/gems has no specification file. Run ‘rake gems:refresh_specs’ to fix this.
I run rake gems:refresh_specs but the problem isn’t fixed. Moreover, tried by creating specification file as well.
After that, removed the irritating message by a single line of code to place in the environment file:
# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')
Rails::VendorGemSourceIndex.silence_spec_warnings = true
Rails::Initializer.run do |config|
