Flutter环境配置提示"flutter command no

给mac系统配置flutter变量时碰到flutter命名找不到的问题。

1. 打开命令行工具 输入

vim ./.bash_profile
// 或者
sudo vi ~/.bash_profile

2.然后编辑该文件, 输入i即可进入编辑模式，添加如下命令“

// 这里是flutter安装的路径,每个人会有差异,找到自己正确的路径
export PATH=/Users/admin/Downloads/flutter/flutter/bin:$PATH

3.保存 .bash_profile 文件：按键盘上的ESC退出编辑模式，然后输入:wq保存并退出文件

此时全局环境变量已经配置成功,可以在命令行输入flutter doctor 命令，这时候会看到相关信息。
