将应用程序部署到Heroku时出错：Railsbridge Installfest - 部署Rails应用程序

时间：2016-10-16 22:51:56

标签： ruby-on-rails ruby ubuntu heroku virtual-machine

我正在执行railsbridge installfest（作为Odin项目的一部分），我在最后阶段遇到了问题：“部署Rails应用程序”。我从终端获得了很多意想不到的结果，当我在教程结束时导航到heroku应用程序的网址时，我得到：

“您要查找的页面不存在。 您可能输错了地址或页面可能已移动。 如果您是应用程序所有者，请检查日志以获取更多信息。“

我在Windows 10上运行Ubuntu 16.04 LTS作为虚拟机。我尝试删除教程期间创建的test_app（在线和关闭）并重新启动，我尝试关闭和启动虚拟机重新开始，但没有运气。我也曾在本网站上查找过类似问题的人，但找不到任何等效的错误消息。

在出现这些问题之前，本教程让我创建了一个rails服务器，它的运行方式完全像我所说的那样。这个问题才在我尝试将应用程序部署到heroku时开始。

我已经包括了我经历的所有阶段。预期的命令行结果（在教程中指定）与我的实际结果不同，我将两者都包括在内，标记为差异。我没有包含符合预期的命令行结果 - 这个问题已经足够长了，而我没有添加所有内容！如果你需要这些信息来帮助我，我已经保存了，所以请告诉我。

道歉，如果我错过了一些明显的东西 - 我完全新编码。

我执行了（在终端）：

git init
git add -A
git commit -m "initial commit"
git log
heroku create

第一次差异：

预期代码：

Enter your Heroku credentials.

Git remote heroku added

实际代码：

Creating app... done, ⬢ tranquil-beyond-97147
https://tranquil-beyond-97147.herokuapp.com/ | https://git.heroku.com/tranquil-beyond-97147.git

然后我在 

gem 'sqlite3'

到

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

group :production do
  gem 'pg'
end

然后（再次在终端）我执行了：

gem install bundler
bundle install --without production

然后我在〜/ railsbridge / test_app / config / routes.rb中添加了一行Rails.application.routes.draw下的行：

添加了一行：

root 'drinks#index'

然后（回到终端）我执行了：

git add .
git commit -m "Updates for heroku deployment"
git push heroku master

第二次差异：

最后，我进入了

我希望我尽可能清楚地表达了这一点，并且非常感谢您提供的任何帮助。

1 个答案:

答案 0 :(得分：0)

我会说你应该检查tranquil-beyond-97147.herokuapp.com，因为这是Heroku为你创建的应用程序的名称。 如果它没有通过，您应该运行heroku logs并粘贴内容，错误的原因始终在日志中。
