最近几天翻找自己的学习笔记时，忽然发现自己的Hexo博客已经长了几个月的草，于是一时兴起又更新了一下Hexo博客，但在构建博客时出现了问题：
## Hexo与Node.js的兼容性

首先，Sophon酱自然是发挥自己作为一名OIer搜（xun）索（zhao）资（ti）料（jie）的能力，找到了这个[Hexo的GitHub Issue](https://github.com/hexojs/hexo/issues/4257)
按照这里面的大牛的说法，这是Node.js 14的一个兼容性问题，Sophon酱使用的版本是这样的：
```
mike@MacBook-Pro ~/hexo $ hexo version [15:14:07]
INFO Validating config
hexo: 5.0.1
hexo-cli: 4.2.0
os: Darwin 19.6.0 darwin x64
node: 14.4.0
v8: 8.1.307.31-node.33
uv: 1.37.0
zlib: 1.2.11
brotli: 1.0.7
ares: 1.16.0
modules: 83
nghttp2: 1.41.0
napi: 6
llhttp: 2.0.4
openssl: 1.1.1g
cldr: 37.0
icu: 67.1
tz: 2019c
unicode: 13.0
```
Node.js 14目前与Hexo存在兼容性问题（目前Hexo官方让然没有修好），所以只要将Node.js降级就可以了。
以下是在macOS系统上的操作
```
brew unlink node #Homebrew操作，解除原来的Node.js在/usr/local/bin/内的链接
brew install node@12 #安装Node.js 12
brew link --overwrite --force node@12 #将新安装的Node.js 12连接到/usr/local/bin/node
```
## macOS升级后NPM更新报错
在写这篇文章之前，Sophon酱使用的Hexo版本号是4.2.1，在听说Hexo 5.0.1更新的消息后准备更新一下试试，然后就遇到了如下问题：
```
mike@MacBook-Pro ~/hexo $ npm install --save [13:48:33]

[email protected] install /Users/mike/hexo/node_modules/nunjucks/node_modules/fsevents
> node-gyp rebuild

```
其中，`
gyp: No Xcode or CLT version detected!`可以看出这个错误是Xcode工具造成的，因此更新一下Xcode工具：
```
mike@MacBook-Pro ~/hexo $ xcode-select --install [14:18:11]
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
```
emmmm好吧，Xcode工具并没有更新，那就只能是上个星期macOS升级时出现了问题。先删除原来的Xcode工具：
```
sudo rm -rf $(xcode-select -print-path)
```
再执行这条命令：
```
mike@MacBook-Pro ~/hexo $ xcode-select --install [14:19:06]
xcode-select: note: install requested for command line developer tools
```
这次再试试更新Hexo:
```
mike@MacBook-Pro ~/hexo $ npm install --save [14:19:19]
>
[email protected] install /Users/mike/hexo/node_modules/nunjucks/node_modules/fsevents
> node-gyp rebuild

大功告成！
