我有一个Angular应用程序,它构建和运行得很好,但是在添加angular/material时出现了一些奇怪的npm依赖性问题,所以我删除了package-lock.json和我的node_modulesnpm i现在安装时不会出错。
但是,我现在在编译时得到一堆TypeScript错误,这是我以前没有的。
我的package.json有以下依赖项:

"dependencies": {
        "@angular/animations": "^14.1.0",
        "@angular/common": "^14.1.0",

我确实有TypeScript 4. 7,但在得到下面的错误后尝试升级(没有任何区别)。
我现在得到的错误是

所以都是从图书馆。我刚刚添加了材料,所以不确定我是否会得到他们之前,但是,我没有这些错误从NgRx图书馆之前
我可以通过添加以下内容来消除这些问题:

"compilerOptions": {
  "skipLibCheck": true,

tsconfig.json,但请注意,隐藏这些错误是最好的主意。
为什么我突然收到这些?

envsm3lx

envsm3lx1#

我不知道它是正确的,但对于这个问题
错误:节点模块/@Angular /材料/日期选择器/索引。d.ts:778:48 -错误TS 2344:类型“MatDatepickerControl未知”不满足约束“MatDatepickerControl {}”。
我遇到了同样的问题,我去了node_modules/@angular/material/datepicker/index.d.ts:778:48,并将MatDatepickerControl unknown更改为MatDatepickerControl any。这对我来说很有效,但我只有一个错误,而不是像你一样的所有列表。
