Looking at it, it is supposed that there is a file of 0.3.3 0.3.4, but there is no 0.3.5 The error caused by the discrepancy here is rich ... To resolve this discrepancy
% gem install mimemagic -v 0.3.5
result
Successfully installed mimemagic-0.3.5
And fold it up
% bundle install
% rails db:create
success! !! !! !! !! !! !!
Please refer to it when loadingError!
