@v-pavanp Could you please check whether you have installed the Ruby related gems per documentation, maybe you can provide your gem list by running gem list in your terminal. Thanks!

[v-pavanp]

Here is the gem list. I could see the second last item in the below list is the one which is listed in the document.

I installed Ruby v2.0.x.

C:Ruby22-x64bin>gem list

* LOCAL GEMS *

bigdecimal (1.2.6)
debase (0.2.1)
debase-ruby_core_source (0.8.4)

test-unit (3.0.8)

Just to say that I had this same error and it is caused by the rdebug-ide command not being available in the workspace root that you are trying to debug.

i.e. if you browse to your workspace in a terminal and try and run it you will get:

C:\my_app>rdebug-ide myapp
'rdebug-ide' is not recognized as an internal or external command,
operable program or batch file.

So you need to fix that first, then vs-code Ruby will work.

The problem here may be specific to your app, but in my case it seems that Bundler does not work perfectly on Windows. I am using binstubs to access the bundled commands, and when I added ruby-debug-ide to the app bundle the binstubs dir was not updated (like it would have been on Linux).

So the solution was to delete my binstubs dir, re-run bundler, and then the binstubs were re-built, now included rdebug-ide.
Now it works in the console, and when I then re-try vscode-ruby, it works there too:

C:\my_app>rdebug-ide myapp
Fast Debugger (ruby-debug-ide 0.6.0, debase 0.2.1, file filtering is supported) listens on 127.0.0.1:1234

@ginty Thanks Stephen, I haven't got time on this bug these days and your solution is likely the right one. And for your information, VS Code will support RHEL from March Release ( maybe after //Build ).

[ginty]

Oh wow, great news re. RHEL (assuming that means RHEL6)!

Also thanks for adding args support, I tried to add it myself but didn't have time, it works great!

@rebornix, @v-pavanp, and @ginty: Basically this comes down to the wrapper script (rdebug-ide or rdebug-ide.bat) not being present in the executable search path. I'll do some experimentation with bundler, but the end result may just be to include a pathToRDebugIDE option in the launch settings.

[HookyQR]

I've setup a clean install of ruby, and bundler and can't reproduce this issue. The only time I can cause a 'ENOENT' is by opening the project without ruby-debug-ide installed. Once installing ruby-debug-ide I did have to restart VSCode to ensure it had read the new %PATH% structure.

[HookyQR]

Closing due to lack of activity.

I had this same issue. I am using windows 10 and installed ruby 2.3.0 (x64) off my C drive, but not the dev kit. The issue is that vscode was looking for the rdebug-ide.bat file and I did not have that. I took the following steps to fix this.

1. I downloaded and installed the Ruby Dev Kit. http://jekyll-windows.juthilo.com/1-ruby-and-devkit/
2. I ran gem and installed the ruby-debug-ide.
   gem install ruby-debug-ide
   This will install a the rdebug-ide.bat file with the other gems in your ruby folder.

After that the debugger worked fine.

Hope this helps some people.

The above fix worked for me. I installed the appropriate DevKit for my Ruby installation, and then I installed ruby-debug-ide. Thanks!

I'm getting this error on Ubuntu 16.04. I'm using ruby 2.4 via rvm. rdebug-ide is installed at ~/.rvm/gems/ruby-2.4.0-rc1/bin/debug-ide, which is in my $PATH. I am able to start rdebug-ide manually via terminal and then connect, but is there any way just point VSCode to where rdebug-ide is kept?

[kattak2k]

How to fix this in linux ?? as there is no devkit available to ubuntu
