## 缘起
因为更新后的的butterfly主题需要新版的Hexo，所以将Hexo更新到了5.4.0。但直接`npm install hexo`产生了一堆Warning，修改`package.json`有可能会破坏依赖。查找了相关资料后才得知更新Node.js项目需要使用`npm-check`和`npm-upgrade`两个包。
## 更新
### 安装
```bash
npm install -g npm-check
npm install -g npm-upgrade
```
### 使用
运行`npm-check`会检测可用的更新。
```bash
hexo ???? UPDATE! Your local install is out of date. https://hexo.io/
npm install --save
[email protected] to go from 5.0.1 to 5.4.0
hexo-abbrlink ???? NOTUSED? Still using hexo-abbrlink?
Depcheck did not find code similar to require('hexo-abbrlink') or import from 'hexo-abbrlink'.
Check your code before removing as depcheck isn't able to foresee all ways dependencies can be used.
Use --skip-unused to skip this check.
To remove this package: npm uninstall --save hexo-abbrlink
hexo-deployer-git ???? MAJOR UP Major update available. https://hexo.io/
npm install --save
[email protected] to go from 2.1.0 to 3.0.0
???? NOTUSED? Still using hexo-deployer-git?
Depcheck did not find code similar to require('hexo-deployer-git') or import from 'hexo-deployer-git'.
Check your code before removing as depcheck isn't able to foresee all ways dependencies can be used.
Use --skip-unused to skip this check.
To remove this package: npm uninstall --save hexo-deployer-git
```
`npm-upgrade`则会更新你的`package.json`文件。
```bash
