有时它会抛出错误,有时它不会抛出错误,有时它甚至会由状态机gem中的某个文件引起.在line_item_decorator.rb：7只有一个数据库查询,没什么特别的.

我在Mac OS X 10.8.5上,但错误也发生在Ubuntu 13上.

知道如何解决这个问题吗？

解决方法 你在Mac上开发吗？ Nokogiri是造成这些分段错误的宝石;这是Mac上一个非常常见的问题,特别是如果你安装了brew.

您可以查看在this url安装nokogiri的正确方法.

首先,从系统中卸载所有nokogiri版本：

gem uninstall nokogiri(select all)

接下来,如果你有brew,请尝试运行：

brew install libxml2 libxsltbrew link --force libxml2 libxslt

最后安装你需要的nokogiri版本(基于你的Gemfile,它是1.6.0)：

gem install nokogiri --version 1.6.0 -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2  \                                     --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib  \                                     --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 \                                     --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include  \                                     --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib

最后,再次捆绑,您应该能够毫无问题地运行规范.
