问题描述
我无法使ruby-debug-ide正常工作.我有一个基本的Rails应用程序，我想在RubyMine中进行调试.在甚至开始RubyMine之前，我需要在无所事事的VM中启用rdebug-ide.导航到项目目录时，我已经在线阅读了，我需要输入以下命令:
I can't get my ruby-debug-ide to work properly. I have a basic rails app, and I would like to debug in RubyMine. Before I even start RubyMine, I need to enable rdebug-ide in my vagrant VM. When I navigate to my project directory, I have read online I need to enter the following command:
rdebug-ide --port 1236 --dispatcher-port 26166 --host 0.0.0.0 - bin/rails s -b 0.0.0.0
但是，当我运行此命令时，会收到以下消息:
However when I run this command, I get this message:
我还尝试了上述命令的修改版本:(额外的破折号)
I have also tried a modified version of the above command: (an extra dash)
rdebug-ide --port 1236 --dispatcher-port 26166 --host 0.0.0.0 -- bin/rails s -b 0.0.0.0
我得到的结果是:起初看起来不错，但随后服务器永不启动.它从不显示服务器信息，它只是坐在这里并挂起，直到我按CTRL + C退出服务器.我无法使rdebug-ide与rails一起使用.有谁知道我该如何解决?
And I get this as a result:This looks good at first, but then the server never starts. It never displays the server info and it just sits here and hangs until I CTRL+C out of the server. I can't get the rdebug-ide to work in conjunction with rails. Does anyone know how I can fix this?
推荐答案
我已经进行了RubyMine远程调试:-)
I've got RubyMine remote debugging to work :-)
开始之前，请确保已安装debase和rdebug-ide:
Before you start, be sure you have debase and rdebug-ide installed:
gem list | grep debase
gem list | grep ruby-debug-ide
sudo gem install debase
sudo gem install ruby-debug-ide
1.启动Rails服务器
首先，您需要启动Rails服务器:
1. Start Rails server
First of all, you need to start the Rails server:
hello_rails$ rdebug-ide --host 0.0.0.0 --port 1234 --dispatcher-port 26162 -- bin/rails server
Fast Debugger (ruby-debug-ide 0.6.0, debase 0.2.2.beta10, file filtering is supported) listens on 0.0.0.0:1234
作为参考，我的Ruby，Rails和Ubuntu版本是:
For your reference, my Ruby, Rails and Ubuntu versions are:
$ ruby -v
ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-linux-gnu]
$ rails -v
Rails 5.1.4
$ lsb_release -a
Description: Ubuntu 16.04.3 LTS
Codename: xenial
正如您所注意到的，服务器似乎从未启动.它只是挂在那里.这实际上是正确的.例如，它从RubyMine挂在那里等待连接.
As you noticed, the server seems never starting. It just hangs there. This is actually correct. It hangs there, waiting to be connected, from RubyMine for example.
现在启动RubyMine(我正在使用RubyMine 2017.2.4)，运行->调试...->编辑配置...
Now start RubyMine (I'm using RubyMine 2017.2.4), Run -> Debug... -> Edit Configurations...
点击加号"+"以添加新配置，然后选择Ruby远程调试.
Click plus sign '+' to add new configuration, and choose Ruby remote debug.
填写表格，然后单击调试"按钮.立即服务器不再挂在那里，Rails服务器开始启动:
Fill the form and click the Debug button. Immediately the server does no longer hang there, and the Rails server gets started:
hello_rails$ rdebug-ide --host 0.0.0.0 --port 1234 --dispatcher-port 26162 -- bin/rails server
Fast Debugger (ruby-debug-ide 0.6.0, debase 0.2.2.beta10, file filtering is supported) listens on 0.0.0.0:1234

最后，您可以在RubyMine中设置断点，并开始远程调试:-)
Finally, you can set breakpoints in RubyMine, and start remote debugging :-)
