'x64_mingw' is not a valid platform
ruby-on-rails
Solution
check your gemfile you will see there like this gem 'tzinfo-data', platforms: [:mingw, :mswin] OR gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]
if you have gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw] then replace this with gem 'tzinfo-data', platforms: [:mingw, :mswin]
and after that save file and fire bundle update command .
Problem
When I run rails new app command the process stops at bundle giving me the above error. I have ruby 2.0.0p195, rails 4.2.0.beta4. I m trying to follow on Michael Hartl's tutorial. The command worked fine I think until I installed this version of rails... I tried to uninstall it but it looks like gem uninstall does not want to work. What should I do?
