而且，我们生产环境的jenkins使用npm构建vue前端product分支，虽然有warning级别的告警信息，却能正常构建完毕。
后仔细对比两个jenkin的构建记录，明显测试环境jenkins构建test分支的日志，明显多了下面的内容：
Creating an optimized production build... Treating warnings as errors because process.env.CI = true. Most CI servers set it automatically. Failed to compile.
最后谷歌搜索关键字process.env.CI,尝试解决办法——npm build前设置该参数值为false：
node -v yarn -v npm -v npm install export CI=false npm run build:test
问题解决，深入内容请自行查找！
