我试图在运行OS X 10.5.8的Mac上获取最新的ruby on rails。一切顺利，直到我尝试更新sqlite3-ruby。我看到其他人遇到了类似的问题，但是他们在Windows上。
这是错误：
sudo gem update sqlite3-ruby Updating installed gems Updating sqlite3-ruby Building native extensions. This could take a while... ERROR: Error installing sqlite3-ruby: ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb can't find header files for ruby.
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sqlite3-ruby-1.2.5 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/sqlite3-ruby-1.2.5/ext/sqlite3_api/gem_make.out Nothing to update
以下是我执行的步骤：
sudo gem update --system
sudo gem install rails
sudo gem update rake
sudo gem update sqlite3-ruby
以下是完整的跟踪：

查看您发布的最新错误，看起来您的更新已成功完成。除了更新文档的麻烦之外，gem本身应该可以正常工作。
答案 1 :(得分：1)
您需要安装header-files for Ruby。
答案 2 :(得分：0)
正如Marcel建议的那样，安装头文件（通过下载和安装最新版本的Xcode）修复了构建错误。 但是我遇到了一个问题，即sqlite3 1.3.3 gem无法找到Sqlite3并建议安装端口。这没有意义，因为它已经安装在Mac OS X上的/ usr / bin中。 问题是它正在寻找sqlite3的通用二进制文件。我通过强制它使用此命令安装i386架构来修复它：
sudo env ARCHFLAGS="-arch x86_64" gem install sqlite3-ruby
