ruby - 无法启动 Rails 服务器 - "Failed to watch"错误 - Bash - Ubuntu - Windows 10

Question

问题是服务器无法启动。我已经设置了以下内容:

• Windows 10 build 1607(周年纪念版)
• Linux 的 Windows 子系统
• GNU bash，版本 4.3.11(1)-release (x86_64-pc-linux-gnu)
• Ubuntu 14.04.5 LTS\n\l
• Rails 5.0.0.1 版
• Ruby 2.3.1 版(使用 - rbenv)
• MySQL 5.5.53

我是 Linux 和 Ruby/Rails 的新手，所以如果我使用了不正确的术语，请原谅我。

经过几天的安装、配置和调试，我能够让一切正常工作(Linux shell、rails、ruby mysql 等)。
我在 Lynda 开始了一个名为“Ruby on Rails 5 Essential Training”的教程，并且能够做到以下几点:

• 创建一个名为 Simple CMS 的新 Rails 项目
• 创建用于开发和测试的 MySQL 数据库
• 在 MySQL 中创建用户

** 当启动 Web 服务器(Puma 通过“rails server”命令)时，我收到了如图所示的错误页面。我搜索了所有与“无法观看”和上述配置有关的 stackoverflow、google、Microsoft 和 GitHub 结果。没有解决方案，最新结果表明由于 Windows 的工作方式，无法运行服务器。在取消我的安装之前，我想在这里询问是否有人遇到过这个问题和/或有解决方案。提前非常感谢您的帮助和花时间阅读本文。迈克

这是错误，包括我用来启动它的命令:(抱歉，它很大)

Answer 1

在@jwsloan 对此 Github issue 的评论中找到了解决方案:

当创建一个新的 Rails 应用时，使用 --skip-listen 来避免 inotify 的问题，像这样:

rails new myproject --skip-listen

这应该允许服务器启动 - 对我有用! :)
