Mac上的Ruby 99％++ CPU使用率

Question

我在Mac机器上运行Ruby时遇到问题。我已经谷歌一段时间但没有找到令人满意的答案，所以我决定问自己。

我使用Visual Studio Code运行一些简单的ruby代码，我看到一些奇怪的东西。 ruby进程占用了99％的CPU。

正如您所看到的，它只占一个简单代码的99％CPU使用率。它将一直运行，直到我强制退出服务，有时不只有一个进程。

这是我运行的代码：

range1 = 1..5
something = 3
something.to_s
print something

这是在Ruby服务中运行文件，内存位置（我不知道它叫什么）：

Ruby为了运行一个简单的代码而占用这么大的CPU能力是否正常？ 是的，当然我可以立即强制退出这个过程，但是每次关闭编辑器时它都会很烦人，它也会使我的机器升温。

编辑： 我在Visual Code的终端和

中运行此代码

  

bookTwo.rb

我和上面提到的完全一样的代码。现在我在Mac的终端中运行代码，但是当我在VS Code终端中运行时它没有问题。
