Node

Ghost 新版本更新了蛮多，node 的推荐版本也变了。现在推荐的版本是 4.x LTS，显然 Raspian 仓库里没有。~~（这个仓库真的有人维护吗？）~~所以我们手动添加 NodeSource 源安装。

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -

看看 node 版本：

apt-cache showpkg nodejs

我这是 4.8.2-1nodesource1~jessie1，手动指定安装

sudo apt-get install nodejs=4.8.2-1nodesource1~jessie1

Done.

npm

显然 npm 也太旧了，会出很多神奇的问题。为了避免这种情况也升级一下

sudo npm install -g npm

node-gyp

npm install -g node-gyp

不解释

However

~~当你做完上面所有的东西的时候，会发现这并没有什么卵用。~~按照官方教程的说法，执行 sudo npm install --production的时候，一个该死的 Error 永远会出现：

最可怕的是，这坨 log 看起来很多，但是什么都没说。在寻找很久之后，在 GitHub 的一个小角落里找到了解决办法：

sudo npm install --unsafe-perm --production

问题解决，别的就和官方教程一样了。

~~于是从此以后，这个网站能不能打开就是缘分了。~~
