我在 typescript 中有一个库，可以将一个类编译为 javascript：
ClassName = ClassName_1 = class ClassName{
...
}
ClassName = ClassName_1 = decorate([
...])
当我使用依赖于该库的 Angular 前端进行编译时，这会出现错误：
./node_modules/.bin/ng build --configuration=development --base-href /client/ --deploy-url /client/
给出以下错误：
ERROR in ./node_modules/library/ClassName.js
Module build failed: Error: Debug Failure. False expression.
我用打字稿编译所有东西，2.9.2因为它是一个 Angular 6 项目。我尝试7.0.0-rc使用 `3.0.3 但我仍然有这个错误，但我可能在这里有一个假阴性。
如果我手动更改 .js 文件，它可以工作：
ClassName = class ClassName{
...
}
ClassName_1 = ClassName
ClassName = ClassName_1 = decorate([
...])
ClassName_1 = ClassName
出现此错误的代码是：
/**
* Endpoint gives the baseDomain of MultiChat and gives the appropriate protocol.
* This is useful so you can pass through the same object to resources and streams types.
*
* A custom object is introduced to allow to pass the same object to use for WebSockets and https calls.
* Paths are also added to easily construct full routes.
*
* The design is to return full new objects so that you do not mix references.
