我正在 Amazon AMI 2010.11.1 上安装 mysql gem，遇到了下一个问题：
# gem install mysql
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
我认为我拥有所有需要的库
# rpm -qa mysql*
mysql-libs-5.1.47-1.2.amzn1.i386
mysql-devel-5.1.47-1.2.amzn1.i386
mysql-5.1.47-1.2.amzn1.i386
# rpm -qa ruby*
ruby-irb-1.8.7.302-1.2.amzn1.noarch
ruby-libs-1.8.7.302-1.2.amzn1.i686
ruby-1.8.7.302-1.2.amzn1.i686
ruby-devel-1.8.7.302-1.2.amzn1.i686
ruby-rdoc-1.8.7.302-1.2.amzn1.noarch
有什么提示吗？
答案1
设置中缺少 gcc。
答案2
您是否已先运行“gem update”和“gem upgrade”？您使用的是什么操作系统？
