TLDR:Node应用程序在本地工作,在Nodester.com上不工作,这似乎是一个npm问题。
详细版本:
我用bogart和couchdb(基本上在http://howtonode.org/bogart-couchdb之后)编写了一个节点应用程序,它在本地运行良好。
我在本地安装了节点扩展
npm install bogart
npm install couchdb
在Nodester上,我通过CLI以如下方式安装了它们
nodester npm install bogart couchdb
它返回了成功。
现在我将工作代码推送到Nodester.com仓库,遇到麻烦,脚本崩溃了,日志说

之后,我尝试了
nodester npm install zlib
它回来了

看起来它尚未完全安装,但是现在,它似乎已启动,而不是由于服务器崩溃而导致的503。但是现在脚本会抛出一个

抱歉,文本墙不对,但这有点奇怪,因为它在本地运行没有任何问题,数据库连接正常。

有任何想法吗?
最佳答案
现在,在nodester开发人员的帮助下,我可以提供一个解释为什么当前无法解决此问题。
在0.6.x之前的版本中,Node.js的zlib库有时会导致某些节点模块出现问题(与绑定有关)。固定为0.6。尝试通过npm在0.4.x上安装pdfkit时也会出现类似问题。
但是,Nodester当前(2012年2月下旬)运行于0.4.9(ish),并且正在开发对0.6.x或更高版本的支持。这意味着,bogart将不得不等待它,直到在Nodester上运行不同版本的Node.js。
感谢Nodester开发人员的快速,广泛和迷人的支持。
