Heroku命令:Heroku Rake db:迁移失败

Question

当我运行Heroku db:migrate时出现错误:

rake aborted!
no such file to load -- sqlite3
/disk1/home/slugs/313735_a606978_6916/mnt/Rakefile:4
(See full trace by running task with --trace)
(in /disk1/home/slugs/313735_a606978_6916/mnt)

当我做

heroku rake db:push

我成功.

我需要在Heroku服务器上安装一些东西吗？

Answer 1

Heroku不支持SQLite数据库.你需要在生产中使用PostgreSQL.

group :production, :staging do
  gem "pg"
end

group :development, :test do
  gem "sqlite3-ruby", "~> 1.3.0", :require => "sqlite3"
end
