当我尝试在Chrome中打开Azure NodeJS React Web应用时，收到以下错误：

PATH="$PATH:/home/site/wwwroot" npm start
ENOENT: no such file or directory, open '/home/site/wwwroot/package.json

当我在Azure SSH中检查/site/wwwroot的内容时，这一点得到了验证：

我在Azure上的构建管道从根目录运行npm install和npm run build，在VScode中运行时是成功的，管道和发布都是成功的，我在VScode中的目录树的外部结构看起来像这样：

├── README.md
├── node_modules
├── package-lock.json
├── package.json
├── public
├── schema.sql
├── server
└── src

因此，npm run build似乎运行成功，创建了一个填充/site/wwwroot文件夹的build文件夹。但Azure需要一个package.json文件。我尝试在VScode的public文件夹中运行npm init，还尝试将npm init添加到Azure管道构建任务，但遇到相同的错误。
另外，不确定这是否相关，但我在public文件夹中添加了一个web.config文件。当我在Azure SSH中查看该文件时，它看起来无法正确读取：

下面是它在VScode中的样子：
