生成不是生成代码。

Question

我试图给出一个生成任何，它不会，这个错误出现，有时什么都不会出现，它会永远运行，什么也不会出现。怎么一回事？我是这个地区的新手。

root@ubuntu:~/Projeto/Projeto_testes/teste_projeto_generator# rails g scaffold User name email
/usr/lib/ruby/vendor_ruby/active_support/core_ext/numeric/conversions.rb:121: warning: constant ::Fixnum is deprecated
/usr/lib/ruby/vendor_ruby/active_support/core_ext/numeric/conversions.rb:121: warning: constant ::Bignum is deprecated

我没有永久地解决这个问题，但是我找到了一个解决办法来避免这个错误。当我给出一个新的rails时，它会生成gem文件，会指定rails版本，我只需更改生成的gem文件，即我“创建”的那个：

source 'https://rubygems.org'

gem 'openssl', '2.0.4'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', github: 'rails/rails', branch: '4-2-stable'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
gem 'rails-i18n', '~> 4.0.0'
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'
end

group :development do
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
end

我不能使用rbenv或rvm来升级我的rails，所以我做了这个“调整”。
