mac m1安装和使用nvm的问题

使用nvm管理多版本node

每个项目可能用的node版本不同，所以需要多个版本node来回切换
但是最近遇到安装v14.19.0时一直安装失败的问题。
首先说明一下，用的电脑是mac M1芯片

解决思路：
1、去node 官网查v14.19.0的版本，发现没有node-v14.19.0-darwin-arm64/node-v14.19.0-darwin-arm64.tar.xz 文件，所以肯定下载不下来。
2、那怎么操作能安装这个版本呢，查了解决办法可以使用以下操作解决

修改～./zshrc在开头加入下面两行：

autoload -Uz compinit
compinit

添加完的文本内容如下：

autoload -Uz compinit
compinit
export PATH="/opt/homebrew/opt/node@12/bin:$PATH"
export PATH="/opt/homebrew/opt/node@14/bin:$PATH"
export PATH="/opt/homebrew/opt/node@16/bin:$PATH"
export PATH="/usr/local/bin:$PATH"export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
export PATH="/opt/homebrew/opt/node@14/bin:$PATH"

然后执行**arch -x86_64 zsh**后再安装即可。

arch -x86_64 zsh

再次安装

nvm install 14.19.0

下载过程中可以看到下载的文件是node-v14.19.0-darwin-x64.tar.xz 这个文件在node官网是存在的。
就可以下载安装成功了
