Question

我已正确配置我的环境，以使用VS Code调试Rails应用。

它对于调试Rails Server正常工作。当我开始调试时，它将启动服务器并在我标记的断点处停止。

但是，我不知道如何调试本地文件，例如rake任务。它甚至可以运行任务，但不会在断点处停止。

下面是我设置环境的方式。

Ubuntu running on WSL2.
VSCode running on windows

安装了扩展程序：

Remote - WSL from Microsoft
Ruby from PengLv

已安装的宝石：

gem install ruby-debug-ide
gem install debase

宝石文件：

gem 'ruby-debug-ide'
gem 'debase'`

/。vscode / launch.json中的调试本地文件配置：

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Rake fd:test",
      "type": "Ruby",
      "request": "launch",
      "cwd": "${workspaceRoot}",
      "program": "${workspaceRoot}/bin/rake",
      "useBundler": true,
      "args": ["fd:test"]
    }
  ]
}

Rake任务本身位于/lib/taks/fd.rake：

namespace :fd do
  task test: :environment do
    a = 10
    p "teste"
    b = 20
    c = 30
  end
end

仅出于比较目的，可以正常运行的调试Rails服务器的配置是：

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [

    {
      "name": "Rails server",
      "type": "Ruby",
      "request": "launch",
      "program": "${workspaceRoot}/bin/rails",
      "args": [
        "server"
      ]
    }
  ]
}

就像我上面说的那样，它运行任务，但不会在断点处停止。有人可以帮我吗？

Ruby on Rails debugging in VS Code建议您需要添加pathToBundler和pathToRDebugIDE。

此外，VS Code对RVM环境变量也不明智，因此我总是为每种配置配置env。

注意：gem env将为您提供GEM PATHS，用于设置GEM_HOME和GEM_PATH变量
注意：echo $PATH-仅使用整个路径

这样做会使您的配置看起来像这样：

{
  "name": "Rake fd:test",
  "type": "Ruby",
  "request": "launch",
  "cwd": "${workspaceRoot}",
  "program": "${workspaceRoot}/bin/rake",
  "useBundler": true,
  "pathToBundler": "/Users/johng/.rvm/rubies/ruby-2.5.3/bin/bundle",
  "pathToRDebugIDE": "/Users/johng/.rvm/gems/ruby-2.5.3@gemset253/gems/ruby-debug-ide-0.7.0/bin/rdebug-ide",
  "args": ["fd:test"],
  "showDebuggerOutput": true,
  "env": {
      "PATH": "/Users/johng/.rvm/gems/ruby-2.5.3@gemset253/bin:/Users/johng/.rvm/gems/ruby-2.5.3@global/binƒ/Users/johng/.rvm/rubies/ruby-2.5.3/bin:/Users/johng/.rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/sbin",
      "GEM_HOME": "/Users/johng/.rvm/gems/ruby-2.5.3@gemset253",
      "GEM_PATH": "/Users/johng/.rvm/gems/ruby-2.5.3@gemset253:/Users/johng/.rvm/rubies/ruby-2.5.3/lib/ruby/gems/2.5.0"
  }
}

无法在VS Code中调试rake任务
