错误TS1086:无法在Angular 9的环境上下文中声明访问器 [英] error TS1086: An accessor cannot be declared in an ambient context in Angular 9

问题描述

我正在学习Angular Material，从"@ angular/material/button"导入{MatButtonModule}时遇到此错误.

I'm learning Angular Material and I'm getting this error when importing { MatButtonModule } from "@angular/material/button".

从我在其他答案中看到的内容来看，这似乎是程序包兼容性问题，但我无法解决.

From what I read in other answers, it looks like package compatibility issues but I couldn't fix it.

推荐答案

根据package.json，您使用的是Angular 8.3，但您已经导入了angular/cdk v9.您可以降级您的angular/cdk版本，也可以通过运行以下命令将Angular版本升级到v9:

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:

ng update @angular/core @angular/cli

这会将您的本地角度版本更新为9.然后，仅同步材料，运行: ng update @angular/material

That will update your local angular version to 9. Then, just to sync material, run: ng update @angular/material
