node.js - 无法在Azure应用程序服务上部署React JS应用程序

Question

我正在浏览一些在 azure 应用程序服务上部署 React Js 应用程序的链接。但我在部署应用程序时遇到一些问题。

我已将所有必要的内容(例如 web.config 文件)添加到 public 文件夹中，并将构建目录添加到工作区。

Deploying web app on azure app service

Deploy Node.js to Azure App Service using Visual Studio Code

遵循了所有步骤，但当我尝试在 azure 应用程序服务上部署时出现以下错误。在部署之前我会运行这些命令

npm run build。

但问题是同一个应用程序可以使用以下命令在本地完美运行npm install 、npm start。

只是为了验证 npm run build 后生成的构建是否有效尝试使用以下命令从构建目录运行应用程序

npm install -g serve

然后

serve -s build

然后应用程序在浏览器中打开。

Answer 1

做了一些谷歌搜索后found solution 。我们需要在 Linux 机器的应用服务配置的启动命令中添加以下命令。

pm2 服务/home/site/wwwroot --no-daemon

步骤:

- Go to App Service

- Navigate to Configuration

- Click on General Settings

- add the above command in Start up command, click on save 

- then restart the server
