ruby-on-rails - 无法在 VS Code 中调试 rake 任务

Question

我正确配置了我的环境以在 VS Code 中调试 rails 应用程序。

它适用于调试 Rails 服务器。当我开始调试时，它会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，比如 rake 任务。
它甚至会运行任务，但不会在断点处停止。

下面是我如何设置我的环境。

Ubuntu running on WSL2.
VSCode running on windows

安装了扩展:

Remote - WSL from Microsoft
Ruby from PengLv

安装的 gem :

gem install ruby-debug-ide
gem install debase

gem 文件:

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

/.vscode/launch.json 中调试本地文件的配置:

{
  // 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

正常工作的调试Rails服务器的配置，仅供比较，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，它运行任务，但不会在断点处停止。
任何人都可以帮助我吗？

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

此外，VS Code 对 RVM 环境变量并不明智，所以我总是为每个配置配置 env。

注:gem env会给你你的GEM PATHS , 用于设置 GEM_HOME和 GEM_PATH变量

注:echo $PATH - 只需使用整个路径

这样做会使您的配置看起来像:

{
  "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"
  }
}
