1 2
npm install -g n n -V #查看n版本
2、管理node版本
1 2 3 4 5 6 7 8 9 10 11
n ls #查看当前已存在的node版本 n run 版本号 #切换到指定node版本
n 版本号 #下载指定版本node n install 版本号 #同上 n lts #下载最新的稳定版本
n Display downloaded Node.js versions and install selection n latest Install the latest Node.js release (downloading if necessary) n lts Install the latest LTS Node.js release (downloading if necessary) n <version> Install Node.js <version> (downloading if necessary) n install <version> Install Node.js <version> (downloading if necessary) n run <version> [args ...] Execute downloaded Node.js <version> with [args ...] n which <version> Output path for downloaded node <version> n exec <vers> <cmd> [args...] Execute command with modified PATH, so downloaded node <version> and npm first n rm <version ...> Remove the given downloaded version(s) n prune Remove all downloaded versions except the installed version n --latest Output the latest Node.js version available n --lts Output the latest LTS Node.js version available n ls Output downloaded versions n ls-remote [version] Output matching versions available for download n uninstall Remove the installed Node.js
