# 查看所有可安装的node版本号
nvm ls-remote
#  安装13.0.0版本的node    # 安装不成功指定仓库  NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist nvm install  13.0.0
nvm install 13.0.0
# 安装15系列中最高版本的node  比如15系列有15.0.0,　　15.0.1,　　15.1.1,　　15.1.2,　　15.2.1,　　15.3.0,那么最后安装的就是15.3.0
nvm install 15
# 安装14.2系列中最高版本的node
nvm install 14.2
# 查看已安装的所有node版本以及默认的版本
nvm list
# 使用13.0.0版本的node
nvm use 13.0.0
# 使用14.2系列的最高版本node
nvm use 14.2
# 卸载13.0.0版本的node
nvm uninstall 13.0.0

nvm is not compatible with the npm config "prefix" option: currently set to ""
Run `npm config delete prefix` or `nvm use --delete-prefix v14.15.4` to unset it.
Creating default alias: default -> v14.15.4

安装v14.15.4版本的时候 报错 nvm与npm的配置文件不兼容
执行一下命令

npm config delete prefix
npm config set prefix $NVM_DIR/versions/node/v14.15.4

之后在安装就可以了 注意：不能再node进程的目录中执行上面命令

升级pm2

npm  install pm2@4.5.5  -g

安装之后关闭窗口 新建窗口执行 pm2 list 会提示

[sgsm@iZ2zebqwvcwhckgto4m1afZ ~]$ pm2 list

>>>> In-memory PM2 is out-of-date, do:
>>>> $ pm2 update
In memory PM2 version: 2.8.0
Local PM2 version: 4.5.5

这个时候执行下 pm2 update 在执行pm2 list 就正常了

多个版本设置默认node版本
