Vue学习之 MacOS 安装 webpack

webpack 简介

Webpack 是一个非常流行的前端构建工具，它可以将多个模块（包括CSS、JavaScript、图片等）打包成一个或多个静态资源文件（bundle），以便用于部署到生产环境。Webpack 支持自定义配置，可以实现各种复杂的前端项目构建需求。

Webpack 主要功能包括：模块加载、代码拆分、文件处理、自动刷新、性能优化等等。

在使用 Vue.js 或 React 等流行的前端框架时，通常会使用 Webpack 对应的插件或脚手架进行项目构建，以便更好地管理项目依赖和资源。

webpack 安装

首先确认一下是否已经安装：

webpack -v

如果提示 command not found: webpack，则表示未安装。

在 Mac OS 上安装 webpack，需要先安装 Node.js 和 npm。建议使用 nvm（Node Version Manager）来管理 Node.js 的版本，在安装完成后再进行下面的安装步骤。

安装 webpack

sudo npm install webpack -g --unsafe-perm=true --allow-root

MacOS 使用 npm install -g webpack 会报权限问题，需要使用 sudo npm install 命令来安装

验证安装结果

webpack -v

这时候会提示安装webpack-cli

安装webpack-cli

sudo npm install webpack-cli -g --unsafe-perm=true --allow-root

验证安装结果

webpack -v

完整步骤如下：
