hexo升级及升级后的问题

hexo升级

首先升级node.js，去官网下载最新安装包，接着执行以下命令升级hexo

npm install -g npm-check-updates # 安装更新工具
ncu # 检查npm软件包更新，需在项目根目录下执行
ncu -u # 更新package.json配置
npm install # 安装package.json配置的版本
hexo version # 更新后检查hexo版本

升级后的问题

升级后执行hexo d部署提交时报错

at ChildProcess.<anonymous> (D:\blog\node_modules\_hexo-util@1.9.0@hexo-util\lib\spawn.js:51:21)
    at ChildProcess.emit (events.js:310:20)
    at ChildProcess.cp.emit (D:\blog\node_modules\_cross-spawn@7.0.2@cross-spawn\lib\enoent.js:34:29)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)

这时候你需要执行ssh -T git@github.com测试是否连接正常，若失败报错

则先去github重新绑定秘钥（如果原来的掉了），步骤和安装是一样，然后去c/Users/youuser/.ssh下删除c:\users\username\.ssh\known_hosts这个文件，重新执行ssh -T git@github.com，选择yes，连接成功，再进行hexo d提交。
