Heroku cedar 没有升级到 ruby​​-1.9.3

Question

尝试将 Heroku cedar 从 Ruby 1.9.2 移植到 Ruby 1.9.3 失败：

更新

我关注了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

我遵循了 heroku 的建议：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 会返回正确的版本：

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

...而且我做到了：

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，这样重新编译后它会崩溃：

2012-07-25T23:18:47+00:00 heroku[router]: Error H10 (App crashed) -> GET gitwatcher.com/ dyno= queue= wait= service= status=503 bytes=
2012-07-25T23:18:47+00:00 heroku[nginx]: 93.34.152.105 - - [25/Jul/2012:23:18:47 +0000] "GET / HTTP/1.1" 503 601 "-" "Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:14.0) Gecko/20100101 Firefox/14.0.1" gitwatcher.com

更新

打开 Heroku 调用请求 #58410

Answer 1

这不是 ruby​​ 版本的问题，实际上我在 heroku 编译期间注意到以下错误，即使它没有阻止部署并且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)

谷歌搜索结果是something similar，我试过了，它有效！

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