MAC安裝Flutter

系統環境要求

操作系統: macOS (64-bit)

磁盤空間: 至少3個G 

1、首先下載Flutter SDK https://flutter.dev/docs/get-started/install/macos#get-sdk

將文件提取到所需位置

cd ~/development
$ unzip ~/Downloads/flutter_macos_v1.12.13+hotfix.7-stable.zip

回車執行命令查看當前變量值

echo $PATH

按回車輸入密碼後用vi打開用戶目錄下的bash_profile文件。一定要用sudo，否則沒權限保存文件，輸入密碼

sudo vi ~/.bash_profile

將flutter工具添加到你的路徑：（壓縮包在上面路徑放在上面地方，比如：/Users/wangpei/Desktop/flutter/bin）

 export PATH="$PATH:`pwd`/flutter/bin"

再次確認是否添加成功

wangpeideMacBook-Pro:~ wangpei$ echo $PATH
/Users/wangpei/.fastlane/bin:/Users/wangpei/Desktop/flutter/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/wangpei/arcanist/bin/

2、檢查開發環境

終端輸入命令：flutter doctor
