Question

我正在使用ruby，我去做一个rake db：migrate，我得到了以下错误：

LoadError：无法加载此类文件 - bundler / setup C：/Sites/raddit/config/boot.rb:4:in <top (required)>' C:/Sites/raddit/config/application.rb:1:in' C：/ Sites / raddit / Rakefile：4：在`

然后我运行bundle exec rake db：migrate并得到此错误

您已要求： sqlite3＆gt; = 0

该捆绑包目前已将sqlite3锁定在1.3.11。尝试运行bundle update sqlite3

我更新sqlite 3，因为它说我已经删除了我的gemfile但是没有任何作用

这是我的Gemfile

  source 'https://rubygems.org'

gem 'devise', '~> 3.5', '>= 3.5.2'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.8'
# Use sqlite3 as the database for Active Record
gem 'sqlite3', '~> 1.3', '>= 1.3.11'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets

要解决这个问题，我刚刚重新安装了bundler，只需执行gem install bundler，然后运行bundle install。它将重新安装所有过去的宝石，并应解决问题。
