在编写对HTML5 File API浏览器支持的支票时，如下所示：
private hasHtml5FileApiSupport;
constructor(@Optional() @Inject(DOCUMENT) document: Document) {
const w = document.defaultView;
this.hasHtml5FileApiSupport = w.File && w.FileReader && w.FileList && w.Blob;
VSCode在w.File && w.FileReader && w.FileList部分下绘制红色弯曲。
有没有摆脱这些的方法？有没有更好的方法呢？
答案 0 :(得分：0)
如果我们使用 Traceback (most recent call last):

NotFoundError (see above for traceback): Restoring from checkpoint failed. This is most likely due to a Variable name or other graph key that is missing from the checkpoint.
Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

类型注入document，那么我们将进行严格的类型检查，而VSCode会绘制弯曲，但是如果我们使用Document而不是any，则会出现错误消失：
Document
