【问题描述】：

我正在尝试运行npm run build，它给了我以下错误：

'webpack' is not recognized as an internal or external command,

我尝试删除 node_modules 文件夹并运行：npm install 但这并没有解决问题。有没有人有这个问题的经验并且可以提出解决方案？

【问题讨论】：

你的 package.json 中有"webpack": "4.16.5"（或任何版本）吗？

标签： npm npm-install

【解决方案1】：

如果没有更多上下文很难判断，但如果您的代码使用的是较新版本的 webpack，请确保您还安装了 webpack 命令行工具，这些工具现在位于单独的 npm 模块中，webpack-cli。
