两天后，我无法再在我的ruby on rails项目中编译javascript资产。如果我不运行预编译命令，则当ruby在运行时编译资产时会发生同样的错误。 'rake assets：precompile'命令因分段错误而中止：
bundle exec rake assets:precompile --trace

在这里，'Segmentatiefout'是'分段错误'的荷兰语。 起初，我以为我搞乱了我的项目，我开始恢复变化以隔离“坏”变化。当这没有帮助的时候，我在一个项目中尝试了“捆绑exec rake资产：预编译”，这个项目我几周都没用，这给我带来了相同的分段错误。
现在我试图找到这个“execjs20120417-15062-69pd5q.js”文件来删除它。即使借助unix'find'命令，我也找不到。也许这个临时文件即使在中止时也会被清除。
我接下来尝试的是重新安装rake，这对我没有帮助。虽然在运行'rake assets：precompile'时出现了同样的错误，但我也尝试重新安装bundler。这也没有用。
接下来的事情有点严厉，我在我的系统上重新安装了ruby和rails。不幸的是，根本没有变化。 Rails版本是3.2.2，重新安装后它是3.2.3。
我尝试的最后一件事是卸载gem execjs，并重新安装它，但也没有帮助。
将RAILS_ENV更改为开发也不会改变任何内容。
当我清除app / assets / javascripts文件夹时，我可以预编译，我可以运行我的应用程序（如Rails assets precompile mysterious error中所述）。我希望ruby能够使用之前成功编译的资产。但是，这意味着我永远不能更改app / assets / javascripts的内容，这是不可取的。如果我删除了那里的所有.js.coffee文件，则会在剩下的.js文件上发生分段错误。
文件clubs.js.coffee是自动生成的，我从未改变过。它是在几周前生成的，并且在2天前从未遇到过我的问题。如果我删除它，同样的故障只发生在另一个.coffe或.js文件中。 clubs.js.coffee包含：
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/
我真的没有想法。在此先感谢您的帮助。

尝试将execjs更改为therubyracer gem。在我切换到rubyracer之前，我有很多execjs的问题。现在一切正常。
group :assets do
gem 'sass'
gem 'coffee-script'
gem 'uglifier'
gem 'therubyracer'
end
干杯！

在我的情况下，这是因为我使用了错误的Ruby版本。记住要仔细检查项目的Ruby版本
