我只是想简单地执行以下操作:
my@ubuntu-lappy:~/rails/app_soft$ heroku rake db:migrate
rake aborted!
Please install the adapter: `gem install activerecord--adapter` (no such file to load -- active_record/connection_adapters/_adapter)
我究竟做错了什么?
过去我已经成功运行 heroku rake db:migrate
gem list
节目
activerecord (2.3.5, 2.2.2)
