使用rails-composer，根据构建器版本获取错误

Question

我正在尝试使用rails-composer来启动一个项目。在composer安装了get之后，我得到了一个错误，脚本停止。下面是错误：

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
    composer  Running 'after bundler' callbacks.
The template [https://raw.github.com/RailsApps/rails-composer/master/composer.rb] could not be loaded. Error: You have already activated builder 3.0.0, but your Gemfile requires builder 3.0.2. Using bundle exec may solve this.

我不确定如何使用bundle exec来解决这个问题。

Answer 1

在命令行中执行此操作

 gem install builder --version '3.0.2'

然后尝试使用rails-composer (&T)
