记录线上环境 Jenkins Vue 打包失败 error code ELIFECYCLE

Jenkins 里面的 Nodejs 版本换了下，然后自动打包的时候老是失败，提取了下日志信息。

发现也没代码上的报错情况，找了一圈找到了错误关键词error code ELIFECYCLE,然后上 Google 搜索了下，找到了一个类似的问题https://stackoverflow.com/questions/42308879/npm-err-code-elifecycle，解决方法大都如下：

1. 清空 npm 的缓存
2. 删除node_modules
3. 删除package-lock.json
4. 重新npm install

npm cache clean --force
rm -rf node_modules
rm -rf package-lock.json
npm install

由于用的Jenkins配置的自动打包，所以先把工作空间内容删了，也就不存在node_modules了，在 Build 中执行 Shellnpm install之前加了如下：

npm cache clean --force
rm -rf package-lock.json

最后重新试了下构建，显示 Success，OK 问题解决。
