前言

更换了新主题，在hexo g和hexo s的时候总会报如下错误，在主题github issues逛了一圈后，感觉应该是我的hexo版本太老了。

➜ hexo s
(node:64285) [DEP0061] DeprecationWarning: fs.SyncWriteStream is deprecated.

决定升级hexo版本，但是没找到很明确的升级hexo的文章，遂做一下记录。

升级

1、全局升级hexo-cli，先hexo version查看当前版本，然后npm i hexo-cli -g，再次hexo version查看是否升级成功。

npm i hexo-cli -g
npm update
hexo version

2、使用npm install -g npm-check和npm-check，检查系统中的插件是否有升级的，可以看到自己前面都安装了那些插件

npm install -g npm-check
npm-check

3、使用npm install -g npm-upgrade和npm-upgrade，升级系统中的插件

npm install -g npm-upgrade
npm-upgrade

4、使用npm update -g和npm update --save

更新全局包与更新生产环境依赖包

npm update <name> -g

npm update <name> --save

save参数：npm install X –save:

  • 会把X包安装到node_modules目录中

  • 会在package.json的dependencies属性下添加X

  • 之后运行npm install命令时，会自动安装X到node_modules目录中

如果不加save参数的话，之后把X包安装到node_modules目录中，不会添加到dependencies文件中。再查看hexo文件夹下面的dependencies文件,可以看到hexo的版本已经更新了。

{
  "name": "hexo-site",
  "version": "0.0.0",
  "private": true,
  "hexo": {
    "version": "3.7.1"
  },
  "dependencies": {
    "hexo": "^3.7.1",
    "hexo-deployer-git": "^0.3.1",
    "hexo-fs": "^0.2.3",
    "hexo-generator-archive": "^0.1.5",
    "hexo-generator-category": "^0.1.3",
    "hexo-generator-index": "^0.2.1",
    "hexo-generator-tag": "^0.2.0",
    "hexo-renderer-ejs": "^0.3.1",
    "hexo-renderer-marked": "^0.3.2",
    "hexo-renderer-stylus": "^0.3.3",
    "hexo-server": "^0.3.2"
  }
}

PS：第四步遇到了错误，错误提示如下：

> fsevents@1.2.11 install /Users/lanvnal/Files/blog/node_modules/hexo/node_modules/fsevents
> node-gyp rebuild

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

gyp: No Xcode or CLT version detected!

其实已经安装过了xcode cli，但是这里还是报错了，估计和苹果新系统有关，重装就好了，操作如下：

如果像以前一样执行xcode-select --install会有如下报错：

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

解决办法：

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

然后再执行第四步，完美升级。
