无法在 RedHat 中安装/识别 Javascript 运行时（适用于 Rails 3.1）
尝试在运行 RedHat（64 位）的专用机器上设置生产部署：
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
在我的一生中，我无法安装 Javascript 运行时和/或被我的 Rails 3.1.0rc6 应用程序识别。
我已经完成了 execjs、therubyracer、libv8 和 Mustang 的 gem 安装...重新启动后仍然出现此错误：
ActionView::Template::Error (Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
(in /var/www/demo-setup/releases/20110825184931/app/assets/javascripts/demos.js.coffee)):
还安装了 node.js 但仍然出现此错误。
有什么想法吗？
Trying to setup a production deployment on a dedicated box running RedHat (64bit):
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
For the life of me, I can't get a Javascript Runtime installed and/or recognized by my Rails 3.1.0rc6 app.
I've done a gem install of execjs, therubyracer, libv8, and mustang ... still get this error after restarting:
ActionView::Template::Error (Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
(in /var/www/demo-setup/releases/20110825184931/app/assets/javascripts/demos.js.coffee)):
Also installed node.js but still get this error.
Any ideas?

我不知道解决方案是什么，但也许这会有所帮助：
错误是从 ExecJS 此处。如果安装了
therubyracergem，则应该通过require "v8"行检测到它 此处。您可以从
irb成功要求“v8”吗？如果是这样，那么这就告诉您 Rails 正在以某种方式在另一组不同的 gem 上运行。你用的是rvm吗？I don't know what the solution is, but maybe this will help:
The error is being thrown from ExecJS here. If
therubyracergem is installed, then it should be detected by the linerequire "v8"here.Can you
require "v8"successfully fromirb? If so, then that tells you that Rails is being run on a different set of gems somehow. Are you using rvm?
