当我尝试 rake db:migrate 时,出现以下错误:
The bundled mysql.rb driver has been removed from Rails 2.2.
Please install the mysql gem and try again: gem install mysql.
rake aborted! no such file to load -- mysql
当我尝试gem install mysql
Building native extensions. This could take a while... ERROR: Error installing
mysql: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb
Can't find header files for ruby. Gem files will remain installed in
/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
也试过了,还是一样的错误。我在 Fedora 10 上。非常感谢帮助。干杯!
