我在尝试为Rails安装gem install mysql2 -v'0.3.17'时遇到了一些问题.当我尝试通过运行gem install mysql2 -v'0.3.17'或gem install mysql2 -v'0.3.17'来安装它时,它给出了以下错误:
ERROR: Error installing mysql2:
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 file for more
details. You may need configuration options.
Provided configuration options:
--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog

--with-mysql-include
--without-mysql-include=${mysql-dir}/include
--with-mysql-lib
--without-mysql-lib=${mysql-dir}/lib
--with-mysql-config
--without-mysql-config
Gem files will remain installed in `..../gems/ruby-1.9.3-p392/gems/mysql2-0.3.17 for inspection`.
Results logged to `.../gems/ruby-1.9.3-p392/extensions/x86_64-darwin-14/1.9.1/mysql2-0.3.17/gem_make.out`
我该如何解决这个问题并成功安装mysql2？
谢谢大家.
