node.js - 无法安装strongloop

Question

您好，我们尝试在几台运行 ubuntu 14.4 的不同服务器上安装 strongloop，但我们每次都会遇到同样的问题。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装 Node 的新 Droplet。没有运气。使用 centos 创建了一个 droplet 并按照说明进行操作。必须安装，但在运行 slc loopback 时，我们收到缺少模块的错误。

终端响应 `npm install -g strongloop

-- 它每次都停在上面。我们可以输入这让我们回到提示符。

任何帮助将不胜感激谢谢雷

我大胆猜测这个 Droplet 有 512mb 左右的 RAM，并且没有配置任何交换空间。

不幸的是，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，这样内核就不会在内存不足时被迫杀死某些东西。

您可以像这样以根用户身份添加交换文件:

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