问题
As stated in the title. I got
C:\...>bundle exec rake db:migrate
rake aborted!
LoadError: cannot load such file -- tzinfo
C:/.../config/application.rb:3:in `require'
C:/.../config/application.rb:3:in `<top (required
)>'
C:/.../Rakefile:4:in `require'
C:/.../Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)
My rails are v4.2.2 and my ruby is v2.2 on Windows 8 (64bit). According to various SO questions I went through I might get this error due to some incompatiblities between the specific gems. Hence here's my gemfile with some options already tried out.
source 'https://rubygems.org'
gem 'rails', '4.2.2'
gem 'sass-rails', '5.0.2'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]
#gem 'tzinfo', '1.2.2'
group :development, :test do
gem 'sqlite3', '1.3.9'
gem 'byebug', '3.4.0'
#gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
end
Any clues?

回答1:
gem 'tzinfo-data' is necessary when developing on Windows (usually it is automatically included on Gemfile when Rails app is created on a Windows machine).
Add gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw] to Gemfile, keep tzinfo commented out and run bundle update.
回答2:
Thanks for the suggestions guys, it helped me a lot. The proper to solution to my problem was:
- remove gemfile.lock
- decrease tzinfo version to 1.2.1, and leave tzinfo-data as provided by user3097405.
- Then another error occured so I had to increase sqlite3 version to 1.3.11. Also it turned out I can decomment webconsle.
So, in the end the Gemfile looks like this
source 'https://rubygems.org'
gem 'rails', '4.2.2'
gem 'sass-rails', '5.0.2'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]
gem 'tzinfo', '1.2.1'
group :development, :test do
gem 'sqlite3', '1.3.11'
gem 'byebug', '3.4.0'
gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
end
And after one more bundle install the rake command executed properly.
回答3:
You probably have a stray reference where you're requireing tzinfo. Does a text search find any references to it in your code?
Also make sure tzinfo isn't in your Gemfile.lock. Delete the Gemfile.lock and rerun bundler if it is.
