尝试将Heroku雪松从Ruby 1.9.2移植到Ruby 1.9.3失败了：

更新
我通过
跟随Heroku docs
ruby '1.9.3'
进入我的Gemfile和bundler --pre：
lsoave@ubuntu:~/rails/github/gitwatcher$ gem list bundler
*** LOCAL GEMS ***
bundler (1.2.0.pre.1, 1.1.4)
lsoave@ubuntu:~/rails/github/gitwatcher$
更新
我遵循heroku建议：If absent or not the first entry, add bin: to the config with heroku config:add.但它不起作用：
lsoave@ubuntu:~/rails/github/gitwatcher$ heroku config -s | grep PATH
GEM_PATH=vendor/bundle/ruby/1.9.1
PATH=bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin
lsoave@ubuntu:~/rails/github/gitwatcher$
...这很奇怪，因为在控制台中运行ruby -v会返回相应的版本：
lsoave@ubuntu:~/rails/github/gitwatcher$ heroku run:detached "ruby -v"
Running `ruby -v` detached... up, run.1
Use `heroku logs -p run.1` to view the output.
lsoave@ubuntu:~/rails/github/gitwatcher$ heroku logs -p run.1
2012-07-25T22:51:57+00:00 heroku[run.1]: Starting process with command `ruby -v`
2012-07-25T22:51:57+00:00 app[run.1]: ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

2012-07-25T22:51:58+00:00 heroku[run.1]: Process exited with status 0
lsoave@ubuntu:~/rails/github/gitwatcher$
更新
...而且我做了：
heroku config:add RUBY_VERSION=ruby-1.9.3-p194
heroku config:add PATH=bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin
recompile ( change + git commit + git push heroku +master )
但没有，它以这种方式重新编译后崩溃：
2012-07-25T23:18:47+00:00 heroku[router]: Error H10 (App crashed) -> GET gitwatcher.com/ dyno= queue= wait= service= status=503 bytes=

这不是ruby版本的问题，事实上我注意到heroku编译期间出现以下错误，即使它没有阻止部署和推送完成而没有其他问题：
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
rake aborted!
Invalid CSS after "...nd-image:url(""": expected ")", was "/assets/twitter..."
(in /tmp/build_19ypab978ku1z/app/assets/stylesheets/application.css)
Tasks: TOP => assets:precompile:primary
(See full trace by running task with --trace)
Precompiling assets failed, enabling runtime asset compilation
Injecting rails31_enable_runtime_asset_compilation
Please see this article for troubleshooting help:
http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting
然后更好地查看heroku日志，我也看到了这个：
psych/syntax_error.rb:5:in 'initialize': wrong number of arguments (1 for 6) (ArgumentError)
并且谷歌搜索结果something similar，我尝试了它的确有效！

2012-07-25T22：11：29 + 00:00 app [web.1]：您的Ruby版本是1.9.2，但您的Gemfile指定为1.9.3
