我目前正在尝试为 ReactJs 构建一个状态管理库。但是一旦我将它实现到我的 React 项目（使用create-react-app）中，它就会开始删除这个错误：
Failed to compile.
path/to/agile/dist/runtime.js 116:104
Module parse failed: Unexpected token (116:104)
File was processed with these loaders:
* ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| if (subscriptionContainer instanceof sub_1.CallbackContainer) subscriptionContainer.callback(); // If Component based subscription call the updateMethod which every framework has to define
|
> if (subscriptionContainer instanceof sub_1.ComponentContainer) if (this.agileInstance.integration?.updateMethod) this.agileInstance.integration?.updateMethod(subscriptionContainer.component, Runtime.formatChangedPropKeys(subscriptionContainer));
| }); // Log Job
|
如果我注释掉错误中提到的突出显示的代码行，它会跳转到另一个点并在那里抱怨。但这不可能是语法错误，因为 TypeScript 也会在 IDE 中抱怨。 …
