我從官方網站安裝了mysql 5.1.61。它已被編譯和安裝，但現在當我嘗試運行簡單rake db:migrate它表現出這樣的錯誤Rails與Mac OS X和mysql2 - LoadError：找不到dlsym符號
Connecting to {:password=>nil, :encoding=>"utf8", :database=>"mnemosyne_spec", :host=>"localhost", :username=>"root", :adapter=>"mysql2"}
rake aborted!
LoadError: dlsym(0x7faaf9048bf0, Init_mysql2): symbol not found - /Users/serg/.rvm/gems/[email protected]/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle
Tasks: TOP => db:migrate
完全跟蹤：
** Invoke db:migrate (first_time)
** Execute db:migrate
Connecting to {:password=>nil, :encoding=>"utf8", :database=>"mnemosyne_spec", :host=>"localhost", :username=>"root", :adapter=>"mysql2"}
