Ruby on rails服务器不会启动

Question

我正在尝试在轨道上启动服务器，但它无法正常运行，为什么会出现这种情况？我没有编辑proyect，这是我第一次尝试启动它。我已经重新安装了宝石并使用了一些不同的选项安装捆绑，但都无济于事。我正在使用Windows。

    from bin/rails:4:in `<main>'

更新： 我在位于另一个文件夹上的新项目上运行相同的命令，没有任何奇怪的字符（例如“á”），也没有成功。这是新的错误。

Answer 1

看起来command_tasks.rb无法找到您的应用程序文件。这可能是因为路径名称。 C:/Users/Julián/Documents/Sites/simple_cms/config/application Julián

似乎误认了您的名字Julián

Answer 2

捆绑安装

可能是错的，但肯定你缺少mysql2 gem，或者Rails需要加载你的应用程序的mysql个文件。

如果您在系统上执行了bundle install，我们会确认这一点 - 我猜测mysql gem会失败

---

MYSQL Gem

考虑到你在Windows上，你可能没有安装MYSQL2 gem - 标准问题，我们编写了关于here的教程：

  

  
1. 在您的系统上安装任何MYSQL C-Connector Header files
  
2. 使用相关参数
安装mysql2 gem   
3. 将libmysql.dll文件复制到ruby/bin目录
  

C-Connector头文件对Windows至关重要，因为它们允许您的系统“读取”＃34; MYSQL命令/请求。这些都没有默认安装，所以你必须自己安装它们（它只是为了安装gem，如果你愿意，你可以把它们除掉）：

安装此文件，然后您可以使用以下安装命令：

gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector-path"'

此 应该在您的系统上安装gem，然后您可以通过从您的mysql文件传输libmysql.dll来完成该操作。 bin目录的ruby/bin目录：

Answer 3

可能是，您应该尝试使用Linux（Ubuntu）的虚拟机。 我第一次开始使用Windows，但是操作宝石和环境非常困难。
