gem在rails中安装mysql问题

我在rails应用措施中碰着错误.

The bundled mysql.rb driver has been
removed from Rails 2.2. Please install
the mysql gem and try again: gem
install mysql.

当我实行做宝石安装mysql它如故无法正常事变,我获得这个错误.

WARNING: Installing to ~/.gem since
/Library/Ruby/Gems/1.8 and /usr/bin
aren’t both writable. WARNING: You
don’t have
/Users/bartligthart/.gem/ruby/1.8/bin
in your PATH,gem executables will
not run.

我也实行了这个,但它没有效

sudo gem install mysql ?? ??with?mysql?config≡/usr/local/mysql/bin/mysql_config

我该怎么做才气安装mysql？ 最佳谜底 你必要先安装它：

apt-get install libmysqlclient-dev
