将应用程序部署到 Heroku 时出错：Railsbridge Installfest—部署 Rails 应用程序
Error When Deploying App to Heroku: Railsbridge Installfest—Deploy a Rails App
我正在执行 railsbridge installfest（作为 Odin 项目的一部分），我 运行 在最后阶段遇到了问题："Deploy A Rails App." 我得到了很多来自终端的意外结果，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。
您可能输入了错误的地址或页面可能已移动。
如果您是应用程序所有者，请查看日志以获取更多信息。"
我正在 运行ning Ubuntu 16.04 LTS 作为 Windows 10 上的虚拟机。我尝试删除教程中创建的 test_app（均在线）和关闭）并重新开始，我尝试在重新开始之前关闭和打开 VM，但没有成功。我也在这个网站上寻找过有类似问题的人，但找不到任何等效的错误消息。
在出现这些问题之前，教程让我创建了一个 rails 服务器，它的功能与我被告知的完全一样。问题仅在我尝试将应用程序部署到 heroku 时出现。
我已经包括了我经历的所有阶段。在预期的命令行结果（如教程中指定的）与我的实际结果不同的地方，我将两者都包括在内，并标记为差异。我没有包括预期的命令行结果——这个问题已经足够长了，我不添加所有这些！如果您需要该信息来帮助我，我已将其保存，请告诉我。
如果我遗漏了一些明显的东西，我深表歉意——我完全编码新手。
