【问题描述】:
我正在尝试将我的 Nodejs/Express 托管服务器设置为在我的 VPS 上运行多个应用程序(Sails.js 应用程序类型),但出现此错误:
/srv/data/web/vhosts/default/node_modules/vhost/index.js:78
throw new TypeError('argument server is unsupported')
^
TypeError: argument server is unsupported
at createHandle (/srv/data/web/vhosts/default/node_modules/vhost/index.js:78:9)
at vhost (/srv/data/web/vhosts/default/node_modules/vhost/index.js:39:16)
at Object.<anonymous> (/srv/data/web/vhosts/default/server.js:46:9)

at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:906:3
当然,我之前安装了所有依赖项。
我的多个应用程序的 Nodejs/Express 基本配置很好,因为它适用于这个 express vhosts 示例配置:
https://github.com/loicsaintroch/express-vhosts
所以这里是我的 nodejs 服务器应用程序结构:
.../vhosts/default/server.js
package.json
/app1
/app.js
/app2
/app.js
/app3
/app.js
这里是我的 server.js 文件,基于之前的 github 示例:
// Module dependencies
var express = require('express');
var vhost = require('vhost');
var app = express();
// vhosts
app
.use(vhost('app1.com', require('./app1/app.js')))
.listen(8080);
还有 package.json 文件:
{
"name": "default",
"private": true,
"version": "0.0.1",
"description": "Default git repository for some web applications.",
"dependencies": {
"express": "^4.2.0",
"vhost": "^2.0.0",
"forever": "^0.11.1",
"static-favicon": "^1.0.0",
"ejs": "^1.0.0",
"morgan": "^1.0.0",
"cookie-parser": "^1.0.1",
"body-parser": "^1.0.0",
"debug": "^0.7.4"
},
"scripts": {
"start": "forever start server.js --prod",
"debug": "node debug server.js"
},
"main": "server.js"
}
错误来自 vhost npm 包:
/**
* Create handle to server.
*
* @param {function|Server} server
* @return {function}
* @api private
*/
function createHandle(server){
if (typeof server === 'function') {
// callable servers are the handle
return server
} else if (typeof server.emit === 'function') {
// emit request event on server
return function handle(req, res) {
server.emit('request', req, res)
}
}
throw new TypeError('argument server is unsupported')
}
好的,我认为 vhost 包 对 sails.js 框架 的 app.js 响应有问题。这是来自我的 Sails.js 应用程序的 app.js 文件内容:
/**
* app.js
*
* Use `app.js` to run your app without `sails lift`.
* To start the server, run: `node app.js`.
*
* This is handy in situations where the sails CLI is not relevant or useful.
*
* For example:
* => `node app.js`
* => `forever start app.js`
* => `node debug app.js`
* => `modulus deploy`
* => `heroku scale`
*
*
* The same command-line arguments are supported, e.g.:
* `node app.js --silent --port=80 --prod`
*/
// Ensure a "sails" can be located:
(function() {
var sails;
try {
sails = require('sails');
} catch (e) {
console.error('To run an app using `node app.js`, you usually need to have a version of `sails` installed in the same directory as your app.');
console.error('To do that, run `npm install sails`');
console.error('');
console.error('Alternatively, if you have sails installed globally (i.e. you did `npm install -g sails`), you can use `sails lift`.');
console.error('When you run `sails lift`, your app will still use a local `./node_modules/sails` dependency if it exists,');
console.error('but if it doesn\'t, the app will run with the global sails instead!');
return;
}
// Try to get `rc` dependency
var rc;
try {
rc = require('rc');
} catch (e0) {
try {
rc = require('sails/node_modules/rc');
} catch (e1) {
console.error('Could not find dependency: `rc`.');
console.error('Your `.sailsrc` file(s) will be ignored.');
console.error('To resolve this, run:');
console.error('npm install rc --save');
rc = function () { return {}; };
}
}
// Start server
sails.lift(rc('sails'));
})();
