    [原]Your Ruby version is 2.2.3, but your Gemfile specified 2.2.2

    在文章 Ruby On Rails中REST API使用示例——基于云平台+云服务打造自己的在线翻译工具 中,从Bluemix上下载的初始Hello World示例代码在本地环境下运行调试时提示:Your Ruby version is 2.2.3, but your Gemfile specified 2.2.2

    我本地Ruby安装的是2.2.3版本,而从Bluemix上下载的示例是2.2.2版本,所以出现此问题


    怎么解决呢?

    我的解决方法是直接修改Gemfile文件中的ruby版本号,如下图:


    初学ruby,不知道这是不是最佳的方法;

    修改完成,保存,然后执行:bundle install

    输出类似下面所示:

    C:\ruby\rbtrans>bundle install
    Using rake 10.4.2
    Using i18n 0.7.0
    Using multi_json 1.11.2
    Using activesupport 3.2.22
    Using builder 3.0.4
    Using activemodel 3.2.22
    Using erubis 2.7.0
    Using journey 1.0.4
    Using rack 1.4.7
    Using rack-cache 1.5.1
    Using rack-test 0.6.3
    Using hike 1.2.3
    Using tilt 1.4.1
    Using sprockets 2.2.3
    Using actionpack 3.2.22
    Using mime-types 1.25.1
    Using polyglot 0.3.5
    Using treetop 1.4.15
    Using mail 2.5.4
    Using actionmailer 3.2.22
    Using arel 3.0.3
    Using tzinfo 0.3.45
    Using activerecord 3.2.22
    Using activeresource 3.2.22
    Using coffee-script-source 1.9.1.1
    Using execjs 2.6.0
    Using coffee-script 2.4.1
    Using rack-ssl 1.3.4
    Using json 1.8.3
    Using rdoc 3.12.2
    Using thor 0.19.1
    Using railties 3.2.22
    Using coffee-rails 3.2.2
    Using jquery-rails 3.1.4
    Using bundler 1.10.6
    Using rails 3.2.22
    Using sass 3.4.19
    Using sass-rails 3.2.6
    Using uglifier 2.7.2
    Bundle complete! 5 Gemfile dependencies, 39 gems now installed.
    Use `bundle show [gemname]` to see where a bundled gem is installed.
    然后执行:rails server 就可以启动Web服务器了

    C:\ruby\rbtrans>rails server
