有时我的测试套件会无缘无故地抛出分段错误。这是输出：

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。
我使用的是Mac OS X 10.8.5，但错误也发生在Ubuntu 13上。
知道如何解决这个问题吗？
答案 0 :(得分：7)
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，特别是如果你已经安装了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，如果你有啤酒，请尝试运行：
brew install libxml2 libxslt
brew 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。
