ruby-on-rails – 狂欢：heroku部署错误

我一直在追随：

remote:        Gem::InstallError: spree_core requires Ruby version >= 2.1.0.
remote:        An error occurred while installing spree_core (3.0.4),and Bundler cannot
remote:        continue.
remote:        Make sure that `gem install spree_core -v '3.0.4'` succeeds before bundling.

我跑的时候

gem install spree_code -v '3.0.4'

它是成功的,之后当我再次运行git push heroku master时,我得到完全相同的错误.

rbenv versions

显示如下：

2.2.2 (set by /Users/Martijn/.rbenv/version)

解决方法

Heroku需要Gemfile中定义的ruby版本,如：
ruby“2.2.1”.更多信息： https://devcenter.heroku.com/articles/ruby-versions.
