我正在使用Rails 4.2.7。我下载了明显要求我使用Ruby 2.1.6，而不是我已经安装了Ruby 2.3.0版本为例...我安装了Ruby，现在“捆绑安装”不起作用
localhost:lti_tool_provider_example-master davea$ bundle install
Your Ruby version is 2.3.0, but your Gemfile specified 2.1.6
所以这就是我所做的。安装Ruby 2.1.6之后然而，现在的“包安装”不工作...
localhost:lti_tool_provider_example-master davea$ rvm install ruby-2.1.6
Warning! PATH is not properly set up, '/Users/davea/.rvm/gems/ruby-2.3.0/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.3.0'.
Warning, new version of rvm available '1.27.0', you are using older version '1.26.11'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc

我怎么不跟我刚安装了Ruby 2.1.3版本干扰恢复“捆绑”命令？
您也可以删除指定Gemfile中Ruby版本的行，并查看它是否可以在您的版本中正常工作。 –
