Question

我已经将我的应用程序部署到Azure几周了，没问题。但是现在我已经将数据库集成到了后端，它会在日志流中看到这个错误，并为浏览器提供500个代码。

Application has thrown an uncaught exception and is terminated: Error: Cannot find module 'async/each' at Function.Module._resolveFilename (module.js:325:15) at Function.Module._load (module.js:276:25) at Module.require (module.js:353:17) at require (internal/module.js:12:17) at Object.<anonymous> (D:\home\site\wwwroot\node_modules\mongoose\lib\schema.js:11:12) at Module._compile (module.js:409:26) at Object.Module._extensions..js (module.js:416:10) at Module.load (module.js:343:32) at Function.Module._load (module.js:300:12) at Module.require (module.js:353:17) at require (internal/module.js:12:17)

猫鼬似乎是个问题，所以当我排除它时，一切都会好起来的。我尝试在我的package.json中包含async-each作为依赖项，但是没有帮助（我之前没有看到带有/ in的模块，所以在这里猜测）

同样在绝望的时刻，我尝试将同一个应用程序推送到另一个Web App服务，但它甚至无法部署。 WebApiClient超时 - 无论这意味着什么。

我将完全相同的应用程序部署到Heroku，它运行良好。

"use strict";
let express = require('express');
let path = require('path');
let favicon = require('serve-favicon');
let logger = require('morgan');
let cookieParser = require('cookie-parser');
let bodyParser = require('body-parser');
let mongoose = require('mongoose');
let passport = require('passport');
let LocalStrategy = require('passport-local').Strategy;
let session = require('express-session');

//routes
let home = require('./routes/index');
let register = require('./routes/register');
let members = require('./routes/members');
let login = require('./routes/login');
let logout = require('./routes/logout');

let app = express();

app.locals.courses = require('./data/courses');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(session({secret:'anything'}));
app.use(passport.initialize());
app.use(passport.session());

//mongoose passport config

require('./db').then(mongoose => {
  mongoose.Promise = global.Promise;
  require('./models/user').then(User => {
    passport.use(new LocalStrategy(User.authenticate()));
    passport.serializeUser(User.serializeUser());
    passport.deserializeUser(User.deserializeUser());
  });
})


//allow CORS requests
app.use(function (req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
});

app.use('/', home);
app.use('/register', register);
app.use('/members', members);
app.use('/login', login);
app.use('/logout', logout);

// catch 404 and forward to error handler
app.use(function (req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});
// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function (err, req, res, next) {
    res.status(err.status || 500);
    res.send(err.message);
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function (err, req, res, next) {
  res.status(err.status || 500);
  res.send(err.message);
});


module.exports = app;

我已成功将<repositories> <repository> <id>smartbear-sweden-repository</id> <url>http://smartbearsoftware.com/repository/maven2/</url> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>smartbear-sweden-plugin-repository</id> <url>http://smartbearsoftware.com/repository/maven2/</url> </pluginRepository> </pluginRepositories>部署到Azure，测试代码也运行良好。也许您的应用程序将使用mongoose文件中devDependencies部分中配置的任何模块。

作为Azure Web Apps作为生产Web服务器，如果您通过git部署应用程序，则默认情况下部署任务将运行package.json，这将忽略develop mod中的依赖项。

因此，您可以尝试按照Custom Deployment Script生成node.js的deplotment脚本并修改npm install --production，找到句子deploy.cmd并修改为call :ExecuteCmd !NPM_CMD! install --production。

同时，您可以按照https://docs.microsoft.com/en-us/azure/nodejs-specify-node-version-azure-apps升级node.js和npm版本的Azure Web Apps运行时，以避免嵌套的call :ExecuteCmd !NPM_CMD! install文件夹结构。
