heroku app/vendor/bundle 显示错误的 ruby​​ 版本

Question

我在生产中遇到了一个在开发中没有发生的错误。它出现在堆栈跟踪中，gem 使用了错误的 ruby​​ 版本（2.1.0），但我在我的 gemfile 中指定了 2.1.3 并按照 heroku 对 ruby​​ 版本进行故障排除。基于其他 stackoverflow 信息，ruby 版本在这里有所作为。有谁知道如何将 app/vendor/bundle 更新到最新版本？

这是我在 Resque 工作人员中发生的错误...

/app/vendor/bundle/ruby/2.1.0/gems/psych-2.0.6/lib/psych.rb:409:in `dump'
...snip...

这是我的 ruby​​ 版本...

heroku run "ruby --version"
ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-linux]

这是 /app/vendor/bundle 中的内容...

heroku run "ls /app/vendor/bundle/ruby"
2.1.0

这是我的 Gemfile ruby​​ 声明....

Answer 1

一个可能的解决方案是在应用程序的根目录中创建一个.ruby-version 文件，然后简单地将2.1.3 放入其中，这样您的应用程序将始终在生产和开发中使用该版本。过去我也遇到过类似的问题，这对我有用。

与此相同的答案：

• Why are we installing Ruby 1.9.2/1.9.3 gems into a 1.9.1 folder?
