当我构建项目时，问题发生了

错误

node_modules/@coreui/angular/lib/sidebar/app-sidebar-nav.d.ts(1,10) 中的错误：错误 TS2305：模块 '"C:/Users/amare/Desktop/New folder/tb /node_modules/@angular/router/router"' 没有导出成员 'QueryParamsHandling'。

Answer 1

更改 @coreui/angular 版本对我不起作用， 但将 node_modules\@coreui\angular\lib\sidebar\app-sidebar-nav.d.ts 文件中的 import 语句更改为：

import { QueryParamsHandling } from '@angular/router/src/config';

将立即生效。

Answer 2

我也遇到了同样的问题，这对我有用。 使用这个版本的 coreui - "@coreui/angular": "2.5.3"

看起来 QueryParamsHandling 在此版本中未按此版本的代码引用。

另外，如果您已经运行 npm install，那么您需要手动删除它，然后使用 2.5.3 版本再次添加它，并确保您在 package.json 中提到了确切的版本（没有购物车或波浪号）。

Answer 3

我设法像这样解决它。转到@angular/router/router"并在QueryParamsHandling声明之前插入单词'export'：

导出声明类型 QueryParamsHandling = 'merge' | '保留' | '';
