I’m trying to upgrade to Rails 5. I deleted my Gemfile.lock file, edited my Gemfile to look like below
我正在尝试升级到Rails 5.我删除了我的Gemfile.lock文件,编辑了我的Gemfile,如下所示
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '5.0.0'
# 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
# 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
gem 'addressable'
gem 'postgresql'
gem 'pundit'
gem 'omniauth-oauth2', '~> 1.3.1'
gem 'omniauth-google-oauth2'
gem 'omniauth-facebook'
gem 'omniauth-twitter'

gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'jquery-modal-rails'
gem 'will_paginate'
gem 'bootstrap-sass'
gem 'autoprefixer-rails'
gem 'whenever', :require => false
gem 'compass-rails'
group :development do
gem 'rails_layout'
end
and ran “bundle install”, only to get the below errors
并运行“捆绑安装”,只是为了得到以下错误
$ bundle install
Your Gemfile lists the gem jquery-rails (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.

Bundler could not find compatible versions for gem "railties":
In Gemfile:
coffee-rails (~> 4.1.0) was resolved to 4.1.1, which depends on
railties (< 5.1.x, >= 4.0.0)
jquery-modal-rails was resolved to 0.0.1, which depends on
railties (< 5.0, >= 3.2.0)
jquery-rails was resolved to 4.1.1, which depends on
railties (>= 4.2.0)
rails (= 5.0.0) was resolved to 5.0.0, which depends on
railties (= 5.0.0)
sass-rails (~> 5.0) was resolved to 5.0.6, which depends on
railties (< 6, >= 4.0.0)
web-console (~> 2.0) was resolved to 2.3.0, which depends on
railties (>= 4.0)
