taro 执行npm run build:h5的时候CPU爆增

复现仓库

https://github.com 浏览器版本: LINUX 使用框架: React

复现步骤

在linux里执行npm run build:h5完后，CPU爆增导致服务器挂掉

期望结果

linux里能打包成功

实际结果

CPU爆增，打包不成功，服务器其他服务也挂掉 jenkins报错

Process leaked file descriptors. See https://www.jenkins.io/redirect/troubleshooting/process-leaked-file-descriptors for more information Build step 'Execute shell' marked build as failure SSH: Current build result is [FAILURE], not going to run.

可以如何优化？
