我认为这是我使用的 NodeJS 版本的问题，但我无法找到实际问题和解决方案。这是heroku日志：

这是我的package.json：

{
     "name": "App"   , "version": "0.0.1"   , "private": true   , "dependencies": {
       "express": "2.5.8"
     , "jade": ">= 0.0.1"   } 
}

我的本地机器上有节点 v0.6.13 并且正在使用它。我应该在我的 中声明一个节点版本package.json吗？哪个版本缓解了这个zlib问题？

我不知道 Heroku 上节点的默认版本是什么，但我认为它已经坏了。我强迫 Heroku 使用我正在使用的 Node.js 版本并且它有效：

{
    "name": "FriendButler"
  , "version": "0.0.1"
  , "private": true
  , "dependencies": {
      "express": "2.5.8"
    , "jade": ">= 0.0.1"
  }
  , "engines": {
      "node": "0.6.13",
      "npm": "1.1.41"
  }
}
