我将我的OSX(Lion)升级为Mavericks,我无法为我的项目安装Nokogiri.

我已经安装了XCode 5.0.1,命令行工具(使用xcode-select --install),并且已经从Homebrew安装了libxml2,我仍然遇到问题.

错误是:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more

我有一个带有文件字段的表单image,但不需要此字段.
当用户不选择表单中的任何文件时,do_upload()始终返回错误.
如何在控制器中执行上载操作之前检查用户是否选择了文件？

好的,我已经尝试过:

• 重新安装RVM;
• 将XCode更新为6.1;
• 安装command_line_tools_for_osx_10.10_for_xcode_6.1.dmg;

什么都不适合我!

我跑的时候rvm install ruby-1.9.2遇到这个错误:

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-1.9.2-p330.
It is not possible to build movable binaries for rubies 1.8-1.9.2, but you can do it for your system only.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

我正在写一个ruby gem,我想让用户使用你自己的yaml文件配置,但我不知道如何测试user_config.yml是否存在于rails配置路径中.
我只想在配置路径中存在此文件时才使用user_config.yml.

我在OSX中使用RVM编译Ruby 1.9.3时出错.我已经搜索了很多解决方案但不是常见的错误.我认为它是一个权限错误,但我不知道如何解决.

看我的make.log文件:
