问题描述
我只是在做一个
sencha app build或
npm run clean && cross-env webpack --env.profile=modern --env.environment=production --env.treeshake=yes
操作系统是Ubuntu 18 LTS。

解决方法
我想跟进此事，因为前几天我有一个顿悟。对于我的家庭项目，当我开始使用开放式工具/ npm方法时，我意识到不必安装Java。在工作中，我们有一个在使用开放工具方法之前创建的项目，因此我们必须下载并安装需要Java的Sencha Cmd exe。
长话短说，我从工作计算机上卸载了Java，删除了node_modules目录和package-lock.json文件，然后重新运行npm安装。当我这样做时，我得到了一个全新的package-lock.json，并且该应用程序在没有Java的情况下构建/运行。我认为管道中有一些聪明人可以检查您是否安装了Java，如果安装了Java，则将获得完全不同的依赖关系。
