运行rake db:create时出现此错误：
LoadError: cannot load such file -- mysql2/mysql2
/Users/vitorqueiroz/dev/pipeline/config/application.rb:10:in `<top (required)>'
/Users/vitorqueiroz/dev/pipeline/Rakefile:5:in `<top (required)>'
(See full trace by running task with --trace)
我必须手动安装mysql2 gem，因为gemfile指定了版本'0.3.20'
我跑了
gem install mysql2 -v '0.3.20' -- --srcdir=/usr/local/include/mysql
捆绑安装运行正常，并且说一切都已安装。
bundle list mysql2的计算结果为：
/Users/vitorqueiroz/.rbenv/versions/2.3.6/lib/ruby/gems/2.3.0/gems/mysql2-0.3.20

还有其他选择吗？
