1、安裝Flutter SDK

下載地址：https://flutter.io/sdk-archive/#macos

解壓到你電腦某個(gè)文件夾下 ，如：

 cd ~/development
 unzip ~/Downloads/flutter_macos_v0.11.13-beta.zip

2、配置環(huán)境變量

  export PUB_HOSTED_URL=https://pub.flutter-io.cn

  export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

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

  export PATH=/Users/liangjia/Documents/flutter/bin:$PATH

  export ANDROID_HOME=/Users/liangjia/Documents/android/sdk

  export PATH=${PATH}:${ANDROID_HOME}/tools

  export PATH=${PATH}:${ANDROID_HOME}/platform-tools

  export PUB_HOSTED_URL=https://pub.flutter-io.cn

  export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

終端配置方法：

env //查看環(huán)境變量

cd ~ && ls -a && sudo vim .bashrc //修改環(huán)境變量，輸入上面的環(huán)境變量

//輸完后依次按 esc => :wq

source ~/.bashrc //配置生效 //在終端再輸入env查看是否成功

flutter doctor //命令查看是否需要安裝其它依賴項(xiàng)來完成安裝

3、-bash: fultter: command not found

git clone -b beta https://github.com/flutter/flutter.git
export PUB_HOSTED_URL=https://pub.flutter-io.cn //國內(nèi)用戶需要設(shè)置
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn //國內(nèi)用戶需要設(shè)置
export PATH=`pwd`/flutter/bin:$PATH

為了讓配置立即生效,上面的命令輸入完成之后，需要在終端輸入：
source ~/.bashrc
