Heroku 捆绑错误

Question

所以 heroku 在使用命令时无法捆绑我的应用程序：

$ git push heroku master

本地打包没问题

$ bundle update

我已经提交并添加了 Gemfile 和 Gemfile.lock 知道为什么会出现此错误吗？

$ git push heroku master

任何有关如何解决此错误的提示将不胜感激。

Answer 1

您的 gemfile 中缺少生产组：

 group :production do
   gem 'pg'
 end

Heroku 不支持 sqlite，因此您可以在 gemfile 中包含上述内容。
但是，我建议您也使用postgresql (pg) 进行开发。它将避免在您的应用程序中不断遇到不兼容问题。

编辑 - 您还应该指定 rails 版本（gem 'rails 3.2.11'），并且可以删除 ruby​​ 行（ruby '1.9.3'）。

Answer 2

如果您在 heroku 上有另一个正在运行的 rails 项目，请尝试将 gemset 或只是将 Gemfile 复制到您当前的项目中，并在该 Gemfile 中添加项目特定的 gem，并尝试使其以这种方式工作。希望你能解决
