无法将 Localhost:3000 Ruby on Rails 页面与 Heroku 链接 - 一个月 Rails 教程

Question

我无法从 Mattan Griffel 的 One Month Rails 教程中安装 Ruby on Rails，因为我使用的是 iOS Mavericks（该教程来自 2013 年）。我不知道我在做什么，我正在努力弄清楚。我终于能够$ git push heroku master 没有错误，但是当我尝试使用 Heroku 提供的链接时，它并没有像预期的那样链接到我的 localhost:3000 Ruby on Rails 页面。

我已经做出了改变，现在我担心我只是把洞挖得更深了。

Demo:omrails Demo$ git push heroku master

我无法从一个月的 Rails 安装 Ruby on Rails Mattan Griffel 教程，因为我使用的是 iOS Mavericks（教程 是从 2013 年开始的）

• 尝试更新的教程。
• 您可以通过运行gem install rails 在 Mavericks 上安装 Rails。 Here's an up to date article on doing that。

我尝试使用 Heroku 提供的链接，但没有链接到 我的 localhost:3000 Ruby on Rails 页面应该是这样的

• Heroku 不应该链接到您的本地主机。
• 当您从计算机 (localhost) 部署代码时，您会将代码发送到另一台计算机（其他主机），您将能够通过该计算机的域名 (your-app.herokuapp.com) 访问您的应用程序）。如果您的部署成功，Heroku 将在终端的最后一行输出您可以在其中查看已部署应用程序的域，例如强大的-fjord.herokuapp.com。
• 回顾一下：当您在计算机上运行rails server 时，Rails 将启动它的内置 Web 服务器并允许您在 localhost:3000 查看您的 Web 应用程序（这就像您在浏览器的地址栏中输入的 URL ）。当您部署到 Heroku 时，它本身就是一台运行网络服务器的计算机，您可以在 Heroku 为您提供的域（或您稍后为其配置的域）查看它，通常类似于 powerful-fjord.herokuapp.com 或您在应用程序时命名的任何名称跑了heroku create my-app-name-here。

最后，阻止git push heroku master 命令成功的错误由输出中的这一行提示：

Sprockets::FileNotFound: couldn't find file 'turbolinks'

这意味着您的 Rails 应用缺少名为 turbolinks.js 的 javascript 文件。您可能需要将 turbolinks 添加到您的 Gemfile：gem 'turbolinks' 或从您的 application.js 中删除此行：*= require turbolinks。这样做，您的部署应该可以工作。

就最新教程而言，上述网站 Railapps 是一个很好的来源。这是他们的教程：https://tutorials.railsapps.org/rails-tutorial
