是否可以使用Ruby 1.9.3在Heroku上运行我的Rails应用程序？如果是这样，怎么样？

I tried this tip: https://github.com/thoughtbot/laptop/pull/14#issuecomment-3192270 .

我试过这个提示：https：//github.com/thoughtbot/laptop/pull/14#issuecomment-3192270。

On deploy I see

在部署我看到

-----> Using RUBY_VERSION: ruby-1.9.3-p0

But my logs show the environment variable is not respected

但我的日志显示环境变量不受尊重

Here's an update for everyone referencing this question... Heroku now allows you to specify your ruby version in your Gemfile, thanks to their addition to the latest version of bundler.

以下是每个引用此问题的人的更新... Heroku现在允许您在Gemfile中指定ruby版本，这要归功于它们添加到最新版本的bundler。

First run:

第一次运行：

gem install bundler --pre

then add ruby '1.9.3' to your Gemfile as such.

然后将ruby'1.9.3'添加到你的Gemfile中。

source 'http://rubygems.org'

ruby '1.9.3'
gem  'rails', '3.2.3'

The full release from Heroku with details is at http://blog.heroku.com/archives/2012/5/9/multiple_ruby_version_support_on_heroku/

Right, so Ruby 1.9.3 is definitely possibly. As you said hacky/experimental solutions were accepted - this is definitely one of them.

是的，所以Ruby 1.9.3肯定是可能的。正如你所说的hacky /实验解决方案被接受 - 这绝对是其中之一。

Enable Heroku Labs's user_env_compile feature for your application.

为您的应用程序启用Heroku Labs的user_env_compile功能。
Set a heroku config variable to RUBY_VERSION to ruby-1.9.3-p0 (heroku config:add RUBY_VERSION=ruby-1.9.3-p0)

将heroku配置变量设置为RUBY_VERSION为ruby-1.9.3-p0（heroku config：add RUBY_VERSION = ruby-1.9.3-p0）
ENSURE that the heroku PATH config variable has bin at the front (heroku config:add PATH=bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin)

确保heroku PATH配置变量在前面有bin（heroku config：add PATH = bin：vendor / bundle / ruby / 1.9.1 / bin：/ usr / local / bin：/ usr / bin：/ bin）

When you next deploy you should see your application using 1.9.3 - the deployment output will show this too;

下次部署时，您应该使用1.9.3查看您的应用程序 - 部署输出也会显示此信息;

Since May 10 it is possible to use Ruby 1.9.3 in an easier way. Just take a look at Heroku's blog: http://blog.heroku.com/archives/2012/5/9/multiple_ruby_version_support_on_heroku/

从5月10日开始，可以更轻松地使用Ruby 1.9.3。只需看看Heroku的博客：http：//blog.heroku.com/archives/2012/5/9/multiple_ruby_version_support_on_heroku/

I had the same problem: Specifying 1.9.3 in my Gemfile, but it was using 1.9.2. This fixed it:

我遇到了同样的问题：在我的Gemfile中指定1.9.3，但它使用的是1.9.2。这解决了它：

heroku config:add PATH=bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin

According to the Heroku Cedar stack definition here Cedar currently only supports MRI 1.9.2. Have you tried contacting Heroku support? They're generally pretty responsive.

根据Heroku Cedar堆栈定义，Cedar目前仅支持MRI 1.9.2。您是否尝试过联系Heroku支持？他们通常很敏感。

Edit: it's possible to 'fool' the platform sometimes into running some binaries such as running Haskell on Heroku so if you're feeling really dedicated you might be able to package something up. I imagine this isn't too easy with MRI though.

编辑：有时可以“愚弄”平台运行一些二进制文件，比如在Heroku上运行Haskell，所以如果你真的很专注，你可以打包一些东西。我想这对于MRI来说并不容易。
