部署Azure App Service时无法安装节点模块

问题描述 投票:1回答:1

我在Azure中有一个Node.js应用服务,我在this tutorial之后创建,然后添加更多东西。我的应用程序包含一个文件:

var http = require("http");
//var mongoClient = require("mongodb").MongoClient; // !!!THIS LINE!!!

var server = http.createServer(function (request, response) {
    response.writeHead(200, {'Content-Type': 'text/plain'});
    response.end('Hello World\n');
});

var port = process.env.PORT || 1337;
server.listen(port);

请记住稍后突出显示的行。

Deployment

由于我使用的是MongoDB,我在package.config中有这一行:

"dependencies": {
  "mongodb": "^3.0.1"
}

Azure在部署时必须运行npm install。所以,在Azure Guidelines for deployment之后,我添加了一个.deployment文件:

[config]
command = bash deploy.sh

请注意,我的应用程序托管在Linux上。文件deploy.sh负责运行安装npm deps的命令:

if [ -e "$DEPLOYMENT_TARGET/package.json" ]; then
  echo Installing NuGetpackages.
  cd "$DEPLOYMENT_TARGET"
  eval $NPM_CMD install --production
  exitWithMessageOnError "npm failed"
  cd - > /dev/null
fi

The problem

如果我保持这一行评论,一切都很好。但如果我取消注释,那么部署就会失败。在本地它可以在我的盒子上工作!但不在云端。检查部署日志时,我可以看到执行了npm install命令:

mongodb没有安装。为什么?。

Using KUDU

如果我登录我的应用程序服务的Kudu工具并打开一个Bash会话,并在npm install --production下运行wwwroot,那么mongodb已成功安装:(

根据您的描述,我按照这个tutorial在Linux上的Azure App Service中创建我的Node.js Web应用程序。 Azure App Service了解package.json和npm-shrinkwrap.json文件,并可以根据这些文件中的条目安装模块。我刚刚创建了以下package.json文件并将其提交到我的bitbucket存储库。

我的存储库:

enter image description here

的package.json:

{
    "name": "app-service-hello-world",
    "description": "Simple Hello World Node.js sample for Azure App Service",
    "version": "0.0.1",
    "private": true,
    "license": "MIT",
    "author": "Bruce Chen",
    "engines": {
        "node": ">=6.9.1"
    },
    "scripts": {
        "start": "node index.js"
    },
    "dependencies": {
        "mongodb": "^3.0.1"
    }
}

然后,我通过Azure Portal检查了我的Azure应用程序的“部署>部署选项”部分下的部署跟踪,并检索了运行部署命令活动,如下所示:

使用KUDU,我发现依赖项已成功安装如下:

此外,我的部署脚本可以自动生成。我不需要Custom Deployment Script
