问题描述

有一个heroku上传的问题。



我遵循Ruby on Rails教程(http://ruby.railstutorial.org),并且在脚手架,我输入heroku rake db:migrate并得到以下错误:


rake中止!请安装postgresql适配器: gem install
activerecord-postgresql-adapter
(pg不是bundle的一部分,将它
添加到Gemfile中。)



任务:TOP => db:migrate => db:load_config(通过使用--trace运行
任务来查看完整跟踪)


第一次,没问题,但这次我得到这个错误。任何想法?

having a problem with a heroku upload. Quite new to RoR so please excuse the beginners question.

I'm following the Ruby on Rails Tutorial (http://ruby.railstutorial.org), and after the scaffolding, I type heroku rake db:migrate and get the following error:

rake aborted! Please install the postgresql adapter: gem install activerecord-postgresql-adapter (pg is not part of the bundle. Add it to Gemfile.)

Tasks: TOP => db:migrate => db:load_config (See full trace by running task with --trace)

First time around, no problem, but this time I'm getting this error. Any ideas?

解决方案

Not quite the answer Simone, but after more digging, the answer finally came up. I needed to do the following:

In the gemfile, I needed to change gem 'sqlite3' to:

group :development, :test do   gem 'sqlite3' end

group :production do   gem 'pg' end

and then I needed to heroku create --stack cedar.

Thanks for your help everyone regardless, and I hope this helps someone in the future.
