Rails：Heroku 首次部署失败答案

【问题标题】：Rails: Heroku Deploying for the First Time FailedRails：Heroku 首次部署失败
【发布时间】：2012-11-06 22:34:58
【问题描述】：

我认为问题在于我使用的是 SQLite3，所以我迁移到 PostgreSQL，但问题仍然存在。该应用程序在本地运行良好。我在打开 heroku 的情况下打开我的应用程序，它给了我以下错误：

Application Error. An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details..

我试图通过查看日志来找到解决方案，但失败了，所以我需要别人的帮助。 这是我的日志，感谢您的帮助！

【问题讨论】：

您的 gemfile 中包含了 Formtastic，对吧？
是的！ group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'bootstrap-sass' gem 'formtastic-bootstrap'
你在运行 rails server 之前尝试过安装 bundle 吗？
是的，并且 bundle install 也给了我错误。我认为 heroku.bat 有问题，我需要将 PATH 设置为 C:\railsinstaller\Ruby1.9.3 .. 你认为这是正确的吗？
好的，问题是“RailsInstaller”和“heroku-toolbelt”相互造成了问题，所以我决定删除 heroku-toolbelt 并将其作为 gemfile 包含在内。但是，我仍然看不到部署的应用程序有什么问题。

标签： ruby-on-rails deployment heroku

【解决方案1】：

对于初次部署的人员，以下是我遇到的问题以及我如何解决这些问题：

1. RailsInstaller 和 Heroku Toolbelt 不完全兼容：如果你在安装 Heroku toolbelt 后遇到问题，建议你把 railsinstaller 和 heroku toolbelt 一起删除，重新安装 railsinstaller。然后，在您的 gem 文件中，只需添加 gem 'heroku' 并运行 bundle install。我不需要任何额外的东西来成功部署我的应用程序。 Heroku Toolbelt 安装 ruby 1.9.2 v，并根据您的偏好添加错误的路径。您可以选择手动将此 PATH 修复到正确的位置，例如 C:RailsInstaller:Ruby1.9.3，但我发现重新安装所有内容更容易。

2。您必须从 SQLite3 迁移到 PostgreSQL：如果您不确定如何操作，请关注 this。

3.按照 Heroku 教程最终部署您的应用程序：关注 this。如果您收到与“对象不存在”类似的错误，请尝试运行heroku run rake db:migrate。

祝你部署顺利！
