关于node.js：无法安装strongloop


Can not install strongloop

您好，我们尝试在均运行ubuntu 14.4的多台不同服务器上安装strongloop，但每次都会遇到相同的问题。它在同一步骤上失败。我们已经完全卸载了node和npm，并按照有关在ubuntu digital ocean上安装的指南进行操作。我们甚至创建了一个预先安装了节点的新Droplet。没有运气。使用centos创建一个小滴，并按照说明进行操作。可以安装，但是在运行slc环回时，我们会收到缺少的模块错误。

终端响应
`npm install -g strongloop

-每次都停在上面。我们可以输入使我们回到提示。

任何帮助将不胜感激

我将大胆猜测此Droplet具有512mb左右的RAM，并且未配置任何交换空间。

很遗憾，这没有足够的内存来运行npm install -g strongloop。最简单的解决方案是简单地添加一些交换空间，以使内核在内存不足时不会被迫杀死某些内容。

您可以像这样将交换文件添加为root：

1

3
# dd if=/dev/zero of=/swap bs=1M count=1024
# mkswap /swap
# swapon /swap
