【问题描述】：

我现在已经浪费了四个小时试图在生产环境中安装我的“keystonejs”项目的所有依赖项。

npm 只是挂起，然后我收到此消息：

这是我的`package.json`

更新：我使用的是节点 5.7 和 npm 3.6

【问题讨论】：

你的 npm 版本是多少？
npm 3.6.0.这发生在亚马逊 t2.micro 实例中
我在看这个建议更新到 npm 3，但你已经在运行它。也许 npm 实际上没有足够的内存？ Keystone 安装了大量的东西 iirc github.com/twbs/bootstrap/issues/19070
有没有什么方法可以在没有npm的情况下下载所有依赖项，然后用npm安装它们？

【解决方案1】：

您的服务器上需要更多内存用于 npm。只需按照https://stackoverflow.com/a/17173973/124416 的说明添加一些：

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1
