使用Rails 4应用程序运行Ruby调试IDE时出错

我在使用Visual Studio代码运行带有Ruby调试IDE的Rails 4应用程序时遇到问题。这就是我得到的错误

额外细节

• Ruby 2.3.0
• Ruby调试IDE 0.6
• IDE:Visual Studio代码+

尝试了不同的变体

• 尝试更新到Ruby 2.3.3
• 已尝试将ruby调试ide降级为0.5
• 已尝试将ruby调试ide升级到0.6.1.beta4

无功而返

额外的

---

我启动了一个新的Rails5+Ruby2.4.0项目，调试效果很好。它使用相同的ruby调试ide版本。所以ruby debug ide的版本应该可以正常工作。

我刚刚通过将rubygems更新到2.6.11版（我认为这是目前可用的最新版本）解决了这个问题

现在，VSCode中的调试再次起作用

我的当前配置

• CentOS 7
• RVM，最新稳定版本
• VSCode，最新稳定版本，Ruby扩展名为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调试IDE 0.6.1b4

我希望这会对您有所帮助。

我猜您的

Gemfile

中包含了一个

this

方法调用。也许它应该是一个注释，而单词前面的

#

丢失了？顺便说一句：错误还表明您使用的是Ruby

2.3

而不是

2.4

——您可能需要对此进行检查。我要补充的是，我使用了相同的扩展来调试Ruby 2.1.x和Ruby 2.2.x Rails应用程序，并且运行良好。它停止了对我来说传递到Ruby 2.3.x的工作（在.0、.1和.3中失败）。谢谢@MarcoSanfilippo，我无法更新到2.4，因为一些库坏了。我将试用2.2.x。太好了，让我试试吧！
