node.js – OpenShift无法使用某些Nodejs依赖项(Koa)

我已经检查了 How to setup KoaJS in Openshift,它仍然无法正常工作.

这是我的package.json文件的一部分：

"ENGInes": {
    "node": ">= 0.12.0","npm": ">= 1.0.0"
  },"dependencies": {
    "co-busboy": "^1.3.0","forever": "^0.14.1","fs": "0.0.2","koa": "^0.18.1","koa-logger": "^1.2.2","koa-router": "^4.2.0","koa-static": "^1.4.9","path": "^0.11.14"
    },"devDependencies": {},"bundleDependencies": [],"private": true,"main": "--harmony app.js"

然后到我的app.js文件.

此代码有效：

var http = require('http');
//var koa = require('koa');
//var app = koa();

var ip = process.env.oPENSHIFT_NODEJS_IP || '127.0.0.1',port = process.env.oPENSHIFT_NODEJS_PORT || '8080';

http.createServer(function (req,res) {
  res.writeHead(200,{'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(port,ip);
console.log('Server running at http://'+ip+':'+port+'/');

这不起作用：

var http = require('http');
var koa = require('koa');
var app = koa();

var ip = process.env.oPENSHIFT_NODEJS_IP || '127.0.0.1',ip);
console.log('Server running at http://'+ip+':'+port+'/');

你可以看到唯一的区别是我没有注释两行.

错误：

service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.2.15 (Red Hat) Server at fela-basickarl.rhcloud.com Port 80

OpenShift上的错误日志说明：

...
.../app-root/runtime/repo/node_modules/koa/lib/application.js:179
function *respond(next) {
         ^
SyntaxError: Unexpected token *
...

一个大笨蛋.

的console.log(process.versions);揭示我使用节点0.10.25,即使我在package.json中声明我希望使用> = 0.12.0：

{ http_parser: '2.0',node: '0.10.25',v8: '3.14.5.10',ares: '1.9.1',uv: '0.10.23',zlib: '1.2.3',modules: '11',openssl: '1.0.0-fips' }

是什么导致OpenShift不使用0.12.2？

#  Uncomment one of the version lines to SELEct the node version to use.
#  The last "non-blank" version line is the one picked up by the code in
#  .openshift/lib/utils
#  Default: 0.10.25
#
#  0.8.24
#  0.9.1
#  0.10.25
#  0.11.11
#  0.10.25
0.12.2
