The require hook is meant more for local development than for production use. require钩不仅用于生产,还用于本地开发。 Ideally you'd precompile before distributing your package.
理想情况下,您应该在分发软件包之前进行预编译。 You are running into https://github.com/babel/babel/issues/1889 .

You'll need to explicitly tell the register hook not to ignore your application. 您需要明确告诉寄存器挂钩不要忽略您的应用程序。
require('babel/register')({
ignore: /node_modules\/(?!my-tool)/
});
