更新节点版本时 Azure 应用中断

Question

我已经将Node.js版本升级到8.8.1，并在进程环境变量iisnode.yml、Web.config和package.json中更新了这个。

尽管如此，发送到应用程序的请求现在会被拒绝并出现以下错误：

The iisnode module is unable to start the node.exe process. Make sure the node.exe executable is available at the location specified in the https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config>system.webServer/iisnode/@nodeProcessCommandLine element of web.config. By default node.exe is expected in one of the directories listed in the PATH environment variable.

我试图更新 Kudu 中的文件路径以反映我感兴趣的 node.exe 的路径 ("D:\Program Files (x86)\nodejs.1.1\node.exe")，但收到一条错误消息说我无权执行此操作.

相关文件：

iisnode.yml:

在 iisnode.yml 中，您 nodeProcessCommandLine 指向 8.1.1 而不是 8.8.1。也许仅此而已？
