cywhat · 2021-09-30 · via Avn - 标签 - cywhat's blog

前景:

服务器中俩个服务需要用到node,但是其中一个服务需要使用低版本的node,另一个则需要高版本node

1.首先安装nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash

#添加环境变量
vim ~/.bashrc

#内容如下:
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

#让配置生效
source ~/.bashrc

2.安装avn

3.设置avn

4.进入想启动项目的根目录新建文件

7
cd XX

#新建 .node-version文件
touch .node-version

#配置需要使用的node版本
echo v8.9.0 >> .node-version   #V后面跟版本号

5.把avn加入系统变量

1
echo `source "$HOME/.avn/bin/avn.sh" # load avn` >> ~/.bashrc    #这里如果是zshrc的话自行更改

6.然后在根目录查看node和npm版本
