Ubuntu 16.04 mean.js安装（不使用digitalocean上的一键应用）

Question

我正在尝试使用以下指南在我的ubuntu 16.04上安装mean.js.而且我一直陷入咕噜咕噜的阶段。

https://www.digitalocean.com/community/tutorials/how-to-install-a-mean-js-stack-on-an-ubuntu-14-04-server

构建节点存在问题，因此我使用nvm

进行安装

https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04#how-to-install-using-nvm

然后是凉亭的问题，这个过程被杀死了。管理通过添加交换来解决这个问题。我有512 MB RAM设置。

https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

现在我的问题是咕噜咕噜。我现在有这个错误。

    /opt/mean$ grunt
    A valid Gruntfile could not be found. Please see the getting started guide for more information on how to configure    grunt:\http://gruntjs.com/getting-started
    Fatal error: Unable to find Gruntfile.

然后当我尝试

时

    /opt/mean$ npm install
    npm WARN checkPermissions Missing write access to /opt/mean/nodemodules/tiny-lr/nodemodules

这是我的第二次尝试。
