json - 通过 npm run 运行时 Webpack 失败

Question

我正在尝试设置 React。当我尝试运行时

npm run webpack -p

它给出了以下错误。

npm ERR! Linux 4.4.0-43-generic

我尝试全局安装 webpack。错误仍然存​​在。

Npm 无法识别 webpack，因为它是依赖项之一，而不是 NPM 脚本。

如果您在本地安装了 webpack(首选方法) - 在 package.json 中添加脚本:

"scripts": {
   "build": "webpack -p"
}

然后使用npm run build运行它。

如果您想使用全局安装的 webpack - 使用 webpack -p 运行它(不使用 npm run)。
