NVM 简介和安装 NVM(Node Version Manager)是一个命令行工具,用于在同一台计算机上管理多个 Node.js 版本。它允许开发人员轻松切换项目所需的 Node.js 版本,并保持不同的项目使用不同的 Node.js 版本。 ### 安装 NVM 要安装 NVM,请按照以下步骤操作: 1. 确保已安装 Git。 2. 在终端中运行以下命令: ```bash curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash ``` 3. 重新启动终端以加载 NVM。 # 2. NVM 配置和管理 NVM 不仅是一个 Node.js 版本管理器,它还提供了丰富的配置和管理选项,使开发人员能够根据自己的需求定制 NVM 的行为。本章节将深入探讨 NVM 的配置和管理功能,包括配置选项、版本管理和高级配置。 ### 2.1 NVM 的配置选项 #### 2.1.1 默认 Node.js 版本设置 NVM 允许用户设置默认的 Node.js 版本,该版本将在没有指定版本的情况下自动使用。要设置默认版本,请使用以下命令: ``` nvm alias default <version> ``` 例如,要将 Node.js 16.14.2 设置为默认版本,请运行: ``` nvm alias default 16.14.2 ``` #### 2.1.2 镜像源管理 NVM 使用镜像源来下载 Node.js 版本。默认情况下,NVM 使用 Node.js 官方镜像源。但是,用户可以根据需要切换到其他镜像源。要查看当前的镜像源,请使用以下命令: ``` nvm config get mirror ``` 要切换镜像源,请使用以下命令: ``` nvm config set mirror <new_mirror> ``` 例如,要切换到淘宝镜像源,请运行: ``` nvm config set mirror https://npm.taobao.org/mirrors/node/ ``` ### 2.2 NVM 的版本管理 #### 2.2.1 Node.js 版本的安装和卸载 NVM 提供了简单的方法来安装和卸载 Node.js 版本。要安装 Node.js 版本,请使用以下命令: ``` nvm install <version> ``` 例如,要安装 Node.js 18.12.1,请运行: ``` nvm install 18.12.1 ``` 要卸载 Node.js 版本,请使用以下命令: ``` nvm uninstall <version> ``` 例如,要卸载 Node.js 16.14.2,请运行: ``` nvm uninstall 16.14.2 ``` #### 2.2.2 Node.js 版本的切换和别名设置 NVM 允许用户轻松地在不同的 Node.js 版本之间切换。要切换到特定版本,请使用以下命令: ``` nvm use <version> ``` 例如,要切换到 Node.js 18.12.1,请运行: ``` nvm use 18.12.1 ``` NVM 还允许用户为 Node.js 版本设置别名,以便更容易地记住和使用它们。要设置别名,请使用以下命令: ``` nvm alias <alias> <version> ``` 例如,要为 Node.js 18.12.1 设置别名 "latest",请运行: ``` nvm alias latest 18.1 ```
