Heroku 没有使用指定的 Ruby 1.9.3答案

【问题标题】：Heroku not using the specified Ruby 1.9.3Heroku 没有使用指定的 Ruby 1.9.3
【发布时间】：2012-08-10 05:21:45
【问题描述】：

升级到 Mongoid 3 和 Ruby 1.9.3。尝试在 Heroku Cedar Stack 上使用 Ruby 1.9.3。我已将以下内容添加到我的 Gemfile 的顶部：

source 'http://rubygems.org'
ruby "1.9.3"

推送到 Heroku，它似乎正在工作

-----> Heroku 接收推送
-----> 检测到 Ruby/Rails 应用程序
-----> 使用 Ruby 版本：ruby-1.9.3
-----> 使用 Bundler 版本 1.2.0.rc.2 安装依赖项

但是，我的应用程序因需要 Ruby 1.9.3 而崩溃。错误如下：

TypeError：无法将数组转换为字符串
来自 /app/vendor/bundle/ruby/1.9.1/gems/moped-1.2.0/lib/moped/node.rb:214:in getaddrinfo' from /app/vendor/bundle/ruby/1.9.1/gems/moped-1.2.0/lib/moped/node.rb:214:ininitialize'

我的路径开头有 bin，建议 here

PATH => bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin

知道可能出了什么问题吗？

更新：

Mongoid.yml

development: 
  sessions: 
    default: 
      database: myapp_development
      hosts: 
        - "localhost:27017"

       Post-install message from newrelic_rpm:
       PLEASE NOTE:
       Developer Mode is now a Rack middleware.
       Developer Mode is no longer available in Rails 2.1 and earlier.
       However, starting in version 2.12 you can use Developer Mode in any
       Rack based framework, in addition to Rails.  To install developer mode
       in a non-Rails application, just add NewRelic::Rack::DeveloperMode to
       your middleware stack.
       If you are using JRuby, we recommend using at least version 1.4 or
       later because of issues with the implementation of the timeout library.
       Refer to the README.md file for more information.
       Please see http://github.com/newrelic/rpm/blob/master/CHANGELOG
       for a complete description of the features and enhancements available
       in version 3.4 of the Ruby Agent.

【问题讨论】：

你检查过 Heroku 认为它使用heroku run 'ruby -v' 运行的版本吗？
@nmott 谢谢，是的。我的实时应用程序提供 1.9.2p290。 Schneems 建议的测试应用程序提供 1.9.3，但 gem 仍然使用错误的版本。
您使用的是哪个版本的 Bundler？您至少需要1.2.0.rc。
@nmott 不是。我刚刚对其进行了更新、捆绑和部署。同样的事情。

标签： heroku mongoid ruby-1.9.3 mongoid3

【解决方案1】：

尝试将此推送到新的 heroku 应用运行：

heroku create

然后按。如果您安装了一组非常特定的 gem，则将应用程序从一个 ruby 版本移动到另一个版本时会出现问题。让我知道这是否有效。

【讨论】：

谢谢。所以我需要重新配置所有插件才能让它工作？
不，我们只是为了调试而这样做，所以您现在唯一需要复制的是您的 rails 应用程序的 gemfile 和 gemfile.lock 部分（以及 rails 应用程序）。然后如果应用程序可以成功$ bundle install 那么它会显示错误是否是我之前提到的错误。
试过了。运行 heroku run "ruby -v" 会得到 ruby 1.9.3p194（2012-04-20 修订版 35410）[x86_64-linux]。但我仍然收到相同的错误 TypeError: can't convert Array into String from /app/vendor/bundle/ruby/1.9.1/gems/moped-1.2.0/lib/moped/node.rb:214:in ` getaddrinfo'
所以你是说以前在 Heroku cedar 上使用相同版本的应用程序和相同版本的 gem，但是当你刚刚将 ruby 版本提升到 1.9.3 时，这会停止工作吗？它在本地与 1.9.3 一起工作吗？你将什么值传递给这个初始化器？ github.com/mongoid/moped/blob/master/lib/moped/node.rb#L214 ?
我以前没有使用过 mongoid，也从未使用过这个 gem，如果我自己在另一个 gem 上遇到这个问题，我会分叉他们的副本，使用 :git => 将它添加到我的 gemfile并在违规行Rails.logger.error host.inspect 上方的代码中添加调试打印输出。提交到 git，推送回你的 fork，运行 $ bundle update moped 以验证它在本地工作，你会看到日志语句的输出，然后推送到 Heroku。我的猜测是 gem 没有正确解析你的配置。如果您与 mongoHQ 联系，他们将能够为您提供比我更多的帮助。
