Bundle目的：

Bundle目的：

• 管理Rails的库
• 帮助你锁定所使用的Rail版本和库的版本

使用Bundle的好处：

• 不用考虑rubygems环境
• 在Gemfile文件里定义所有依赖

检查依赖：

bundle check

打包应用：

bundle pack

解包应用：

bundle install

锁定版本：

bundle lock

命令一览:

bundle check # Checks if the dependencies listed in Gemfile are satisfied by currently installed gems

bundle exec # Run the command in context of the bundle

bundle help [TASK] # Describe available tasks or one specific task

bundle init # Generates a Gemfile into the current working directory

bundle install # Install the current environment to the system

bundle lock # Locks the bundle to the current set of dependencies, including all child dependencies.

bundle pack # Packs all the gems to vendor/cache

bundle show # Shows all gems that are part of the bundle.

bundle unlock # Unlock the bundle. This allows gem versions to be changed
