全新安装"Unexpected mongo exit code null. Restarting."上流星抛出错误



我正在设置一个丛请求服务器(https://github.com/lokenx/plexrequests-meteor/blob/master/README.md)全新的ubuntu安装。

我开始下载流星curl https://install.meteor.com/ | sh,它似乎没有任何问题。然后,我克隆了plex请求项目,并从该目录中运行meteor

这是生成的错误:

plex@johnpc:/home/plex/plexrequests-meteor$ meteor

我想知道我是否缺少其他一些依赖项,或者是什么原因导致了这个问题。我的猜测是,这可能是某种权限问题,因为我在这台服务器上已经遇到了一些权限问题,但我不确定在哪里。在引发错误的目录上,权限似乎是正确的。

plex@johnpc:/home/plex/plexrequests-meteor$ ls -al /var/lib/plexmediaserver

-rw-------  1 plex plex  638 Nov 29 17:17 .viminfo

另一个问题是,我可能缺少依赖项——我安装了mongo,看看这是否能解决问题,但它似乎一直存在。我尝试了这里建议的解决方案,通过设置lang-env变量和重新设置流星,没有任何解决方案。想法?

下面显示的系统在我的macbook pro上运行得很完美,但一旦我试图在我新的ubuntu(ubuntu 14.04 x64)盒子上重新创建它,就会出现这个问题。

另一种可能性是,这可能与记忆有关。我在网上看到人们在记忆耗尽时与流星搏斗。这看起来并没有发生在我身上,但如果我错了,请纠正我。

根据我使用cloud9的经验,它有768MB的内存,在流星运行几分钟并且内存已满后,我会遇到同样的异常。

如果你想用流星进行开发,你需要比现有RAM多得多的RAM。如果你只想运行它,你可以构建应用程序,并将其作为一个简单的节点应用程序运行,但这不是MongoDB附带的,你需要添加额外的功能。
