环境变量$PATH

查看

在命令行
env 
或者
echo $PATH

修改

# vim ~/.zshrc

export PATH="/Users/xueyueshuai/apache-maven-3.8.1/bin:$PATH"
export PATH="/usr/local/sbin:$PATH"

export PATH="/usr/local/opt/php@7.2/bin:$PATH"
export PATH="/usr/local/opt/php@7.2/sbin:$PATH"

export PATH="/usr/local/opt/php@8.1/bin:$PATH"
export PATH="/usr/local/opt/php@8.1/sbin:$PATH"
export PATH="/usr/local/opt/node@14/bin:$PATH"

以此类推...

改了要刷新

source ~/.zshrc
