我已经试过

• gem install fileutils
• sudo aptitude install libfileutils-ocaml-dev（在抓救命稻草文件实用程序）
• gem update --system
• gem update

Answer 1

看起来像它a bug in capifony 2.1.5，尝试grepping为require "FileUtils"与require "fileutils"更换。这也许等待补丁？

Answer 2

我尝试创业板安装导轨时有几分相似的错误那天晚上，事实证明我错误地信任apt-get来获得我需要的一切。

我敢打赌，在安装软件包并确保它们实际上是你想要的时候，你比我更小心一点，但这里是我安装（大致）修复它的东西。

sudo apt-get install ruby-full build-essential

sudo aptitude install ruby build-essential libopenssl-ruby ruby1.8-dev

Answer 3

你有交响乐部署的宝石，它会自动添加到您的部署：

gem uninstall capifony 

使用gemsets或bundler exec capistrano ...来解决这个

Answer 4

由于文件实用程序是Corelib的一部分，那么它应该在任何红宝石中如果你使用RVM安装ruby，它可以编译它。我自己也遇到了类似的问题，其中一些corelib没有在那里，结果发现当我用RVM编译ruby时，我没有安装一些依赖项。

这些是所有ruby corelib特性以及RVM所需要的一些特性的全部要求。使用rvm requirements

apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion 

现在，完全删除红宝石和来源然后重新安装（找到。（否则它可能是以前的配置选项可能无法得到取消设置，让你在同一个地方）

rvm reinstall 1.9.3-p125 

Answer 5

你会发现，require 'FileUtils'一般会在Mac OS X上工作，但它应该是小写的fileutils。问题在于，大多数情况下，Mac OS X使用的是不区分大小写的文件系统，因此，当您部署或转移到Linux或其他文件系统（如ZFS）并打开区分大小写时，它将失败。
