Angular 找不到名称'；缓冲区'；角度应用中的误差

我正在处理我的应用程序，这个错误消息开始出现，我不知道为什么。一切都很好，我不确定我能做些什么来导致这些错误的发生。我已尝试安装@types/node并添加了

"angularCompilerOptions": {
    "types" : ["node"]
 }

到我的tsconfig.json，但这不起作用

ERROR in node_modules/@angular/compiler-cli/src/ngtsc/file_system/src/types.d.ts:37:43 - error 
TS2591: Cannot find name 'Buffer'. Do you need to install type definitions for node? Try `npm i 
@types/node` and then add `node` to the types field in your tsconfig.

我真的被难住了。有没有解决这个问题的办法？

可能只是删除节点_模块并运行npm i…？我尝试了这个方法，但不幸的是，它不起作用。
