I am having a problem running a Rails 4 app with Ruby Debug IDE using Visual Studio Code. This is the error I get.

/home/ziyan/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/specification.rb:2158:in `method_missing'

Extra details

  • Ruby 2.3.0
  • Ruby Debug IDE 0.6
  • IDE: Visual Studio Code + vscode-ruby

Different variations tried

  • Tried updating to Ruby 2.3.3
  • Tried downgrading ruby-debug-ide to 0.5
  • Tried upgrading ruby-debug-ide to 0.6.1.beta4

With no success

Extra

I started a new Rails 5 + Ruby 2.4.0 project and debugging works fine with it. It uses the same ruby-debug-ide version. So the version of ruby-debug-ide should be working.

我刚刚通过将 ruby​​gems 更新到版本 2.6.11 解决了这个问题（我认为它是今天可用的最新版本）。

$ gem update --system

现在在 VSCode 中调试又可以工作了。

我目前的配置。

  • CentOS 7
  • RVM，最新稳定版
  • VSCode，最新的稳定版，带有 Ruby 扩展 0.10.4
  • Rails 4 - Ruby 2.3.3（目前正在开发基于 Solidus 的电子商务）
  • Debase 0.2.1，Ruby-Debug-IDE 0.6.1b4

我希望这能帮到您。
