在执行npm run构建脚本执行后，我很难到达这个npm错误的底部。终端中的错误如下：
npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! vincent-site@1.0.0 build: `webpack --mode production`
npm ERR! Exit status 2
npm ERR!
npm ERR! Failed at the vincent-site@1.0.0 build script.
npm ERR! This is probably not a problem with npm.
There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:

描述性不强。在撰写本文时（6.4.1），我正在使用最新的npm版本；在撰写本文时，我正在使用最新的节点（11.1.0）。我还使用Babel 7和Webpack 4进行编译。到目前为止，我已经尝试了一些方法。
在同时使用最新版本的npm / node和旧版本时，我尝试了以下步骤：
仍然收到错误。

第1步：$ npm缓存清理--force
步骤2：删除node_modules文件夹
第3步：删除package-lock.json文件
第4步：npm安装
要重新开始，请$ npm run start或npm run build
这对我有用。希望它对您有用。
