小编der*_*e23的帖子

我试图编译我的项目，但出现错误：

Error: Error on worker #3: Error: No typings declaration can be found for the referenced NgModule class in static withConfig(configOptions, 
        // tslint:disable-next-line:max-line-length
        breakpoints = []) {
            return {
                ngModule: FlexLayoutModule,
                providers: configOptions.serverLoaded ?
                    [
                        { provide: LAYOUT_CONFIG, useValue: Object.assign(Object.assign({}, DEFAULT_CONFIG), configOptions) },
                        { provide: BREAKPOINT, useValue: breakpoints, multi: true },
                        { provide: SERVER_TOKEN, useValue: true },
                    ] : [
                    { provide: LAYOUT_CONFIG, useValue: Object.assign(Object.assign({}, DEFAULT_CONFIG), configOptions) },
                    { provide: BREAKPOINT, useValue: breakpoints, multi: true },
                ]
            };
        }.

我使用了 …

我想在 IntelliJ 中运行新项目。我再次遇到了一些我认为 pom.xml 中的依赖关系的问题。

我尝试过很多 stackoverflow 主题。不工作。

我已经尝试过全新安装（全新安装构建成功后，但当我想运行 mvn spring:boot:run 时出现错误），删除 m2 文件夹...这是控制台输出

当我尝试测试我的服务时出现此错误我做了本教程中的所有操作
