有任何人出现过这个错误么？求救

Errno::ENOMEM: Cannot allocate memory - node
看起来是没有装 node
是因为要把coffeescript转成javascript时，
execjs 找不到 node.js 的工具来转换？
用你的linux版本来安装node.js 试试。
结果怎样也告知一下。
node.js在有些linux版本是node, 有些是nodejs，
须确认一下安装包的名称。

sudo apt-get install nodejs
sudo apt-get install node
一样的错误.

Errno::ENOMEM: Cannot allocate memory - node
会不会是内存不够?需要加大服务器内存?

你先 free -m 看看内存及swap的状况为何？
网络上也是有类似的情形，而再加文档式的swap来解决；
但是否有效就不得而知了。
