Node 多版本管理器(Node VersionManager,nvm)是一个通用的叫法,它目前有许多不同的实现。
我喜欢用n管理器，没错，名字就是一个字母n(github.com/visionmedia…)
[livingbody@localhost etc]$ cnpm install -g n Downloading n to /usr/local/node-v10.13.0-linux-x64/lib/node_modules/n_tmp Copying /usr/local/node-v10.13.0-linux-x64/lib/node_modules/n_tmp/_n@2.1.12@n to /usr/local/node-v10.13.0-linux-x64/lib/node_modules/n Installing n's dependencies to /usr/local/node-v10.13.0-linux-x64/lib/node_modules/n/node_modules All packages installed (used 5ms(network 3ms), speed 0B/s, json 0(0B), tarball 0B) [n@2.1.12] link /usr/local/node-v10.13.0-linux-x64/bin/n@ -> /usr/local/node-v10.13.0-linux-x64/lib/node_modules/n/bin/n [livingbody@localhost etc]$
