使用NVM安装和管理Node

官方GitHub仓库 点我去

NVM（Node version manager）顾名思义，就是Node.js的版本管理软件，可以轻松的在Node.js各个版本间切换，项目源码GitHub

=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

生效

[root@centos-node1 ~]# source ~/.bashrc

验证安装

[root@centos-node1 ~]# command -v nvm
nvm

使用NVM管理NODE

1. 查看可用的远程列表

[root@centos-node1 ~]# nvm list-remote
   v0.1.14
        v0.1.15
        v0.1.16
        v0.1.17
        v0.1.18
        v0.1.19
        v0.1.20
        v0.1.21
      ......省略.......
       v16.13.0   (LTS: Gallium)
       v16.13.1   (LTS: Gallium)
       v16.13.2   (LTS: Gallium)
       v16.14.0   (LTS: Gallium)
       v16.14.1   (LTS: Gallium)
       v16.14.2   (LTS: Gallium)
       v16.15.0   (Latest LTS: Gallium)

2. 安装指定版本，推荐安装(Latest LTS: Gallium)版本的

[root@centos-node1 ~]# nvm install v12.22.12

3. 查看本地已经安装的

[root@centos-node1 ~]# nvm list

default -> v12.22.12
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v12.22.12) (default)

lts/* -> lts/gallium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.12
lts/fermium -> v14.19.2 (-> N/A)
lts/gallium -> v16.15.0 (-> N/A)

4.切换版本

nvm use v0.10.30

6.设置默认版本

nvm alias default v0.10.30
