actionmailer (2.2.2)
actionpack (2.2.2)
activerecord (2.2.2)
activerecord-postgresql-adapter (0.0.1)
数据库.yml
development:
adapter: postgres
encoding: unicode
database: witcamp
pool: 5
username: root
password: 123456
test:
adapter: postgres
encoding: unicode
database: witcamp
pool: 5
username: root
password: 123456
最佳答案
在database.yml文件中应该是。
适配器:postgresql
而且,在GemFile中必须有:gem'pg'
关于ruby-on-rails - 请安装postgres适配器:`gem install activerecord-postgres-adapter`,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/35682577/
