尝试上传代码时出现版本错误。我见过其他帖子,但由于我从Cloud9工作,似乎这些并没有正确地指导我。当使用命令" ruby -v"它显示了2.2.2
下面的Gem文件:
source 'https://rubygems.org'
ruby '2.2.2'
gem 'rails', '4.2.1'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
# for Heroku deployment - as described in Ap. A of ELLS book
group :development, :test do
gem 'sqlite3'
gem 'byebug'
gem 'database_cleaner', '1.4.1'
gem 'capybara', '2.4.4'
gem 'launchy'
gem 'rspec-rails', '3.3.2'
gem 'ZenTest', '4.11.0'
end
group :test do
gem 'cucumber-rails', :require => false
gem 'cucumber-rails-training-wheels'
end
group :production do
gem 'pg'
end

答案 0 :(得分:0)
https://docs.c9.io/docs/writing-a-ruby-app#rvm-support 目前,默认版本为1.9.3
所以在C9控制台上:
rvm use 2.2.2
如果找不到2.2.2,我认为你需要按照该帖子所提到的每个项目安装它。
curl -L https://get.rvm.io | bash -s stable
或者,您也可以拥有一个名为.ruby-version的项目文件 如何生成:
echo 2.2.2 > .ruby-version
如果将来你在本地使用它,RVM应该尊重这个以及rbenv 更多信息: https://rvm.io/workflow/projects
