我将 Windows 重置为出厂设置，
我需要的所有应用程序都安装在 D 盘上（node、git、vsc、webstorm 等）。
但是现在它们在系统中“未注册”，并且 cmd 看不到命令，例如“node -v”
问题是，如何使所有这些变得“活跃”并正常工作，以便整个系统可以再次看到这些程序？
以及重置 Windows 后安装在其他磁盘上的任何程序
这是我的第一次经历，所以不要打败我）
我使用服务器后面的 HttpListener 来实现 HTTPS，并没有引起任何抱怨。我想切换到 php-fpm，但我不知道它会有什么效果。有谁知道这个问题，告诉我 Linux 上最新版本的 php-fpm 有多可靠，相同算法在相同数据集上的性能是否可以比较？
我有一个组件，当按下按钮时会出现一个对话框。此方法与按钮相连。
public onBurger() {
const dialogRef = this.dialog.open(BurgerMenuComponent, {
width: '100%',
disableClose: true
})
dialogRef.afterOpened().subscribe(() => {
console.log('Диалог открыт');
});
dialogRef.afterClosed().subscribe(result => {
console.log('Диалог закрыт с результатом:', result);
});
}
在设计器中，MatDialog
与组件连接的模块相连的组件中导入的MatDialogModule
窗口没有打开，在控制台中我只看到
对话框关闭，结果为：undefind 我怎样才能使它在我单击按钮时打开一个对话框，其中包含我需要的组件
我正在使用 Docker 版本 20.10.21，构建 baeda1f。操作系统 Windows 11。决定在 Nest.js 上“dockerize”该应用程序。我通过 nest cli 创建了一个空项目并安装了 nodemon，虽然这里基本上不需要它，但没有它跟踪也可以工作。应用程序运行正常，一切正常。然后我决定创建一个 Docker 镜像和一个基于它的容器。这是我的Dockerfile
FROM node:latest
WORKDIR /app
RUN npm install -g nodemon
COPY package.json .
RUN npm install
COPY . .
EXPOSE 3030
CMD ["npm", "run", "start:dev"]
这是我的package.json

import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(process.env.PORT ?? 3030);
}
bootstrap();
这就是我的app.service.ts文件的样子
import { Injectable } from '@nestjs/common';
@Injectable()
export class AppService {
getHello(): string {
return 'Hello World!2';
}
}
这就是我创建图像的方式
docker build -t server-nest:v1.0 .
这就是我创建容器的方法
docker run --name test-nest2 -p 3002:3030 --rm -v C:\Users\Dmitrij\work\nest_docker_setup:/app -v /app/node_modules server-nest:v1.0
绝对路径是正确的。这是应用程序的文件结构
究竟问题是什么？图像和容器已创建，但变更跟踪不起作用。那些。如果我更改 app.service.ts 文件中的行 return 'Hello World!2';然后通过 GET 请求 http://localhost:3002 我获得了之前的值。但即使没有 Docker，一切仍然正常。我想尝试安装 nodemon 并看看它是否可以工作，但是它没有工作。我尝试在容器运行时检查 nodemon 是否以这种方式安装。在 Docker 容器内，我运行命令来检查 nodemon 是否看到更改：
docker exec -it test-nest2 sh
nodemon --watch src --exec "nest start --watch"
我在控制台中收到了这个响应

我尝试更改端口，但没有什么帮助。我希望有人能提出一些建议。
我怎样才能得分，以便当我进球时，记分牌上就会增加一分？
