Ruby on Rails不使用rbenv中定义的版本

Question

I want to use version 2.2.2 of Ruby, then

r2d2@r2d2-acer ~/ApenasMeu/myapp $ rbenv global
system
r2d2@r2d2-acer ~/ApenasMeu/myapp $ rbenv versions
  system
* 2.2.2 (set by RBENV_VERSION environment variable)

However, the default home page of RoR, it appears that use this version:

Ruby version 1.9.3-p484 (x86_64-linux)

How to solve it?

Answer 1

如果您使用的是捆绑程序，则可以在Gemfile指定ruby版本-只需在您的Gemfile添加ruby "2.2.2"这样的行Gemfile （我一直在顶部/附近看到它-不知道是否需Gemfile或只是约定），然后运行bundle install 。
