按照官方文档一步步执行操作 docs.flutter.dev/get-started…
Step 1 下载Flutter SDK
storage.googleapis.com/flutter_inf…
Step 2 解压Flutter SDK
cd $your_flutter_develop_path
unzip $your_flutter_download_path/flutter_macos_3.3.8-stable.zip
Step 3 配置环境变量
echo PATH="$PATH:$your_flutter_develop_path/flutter/bin" > ~/.bash_profile
Step 4
flutter doctor 结果报以下错误。

很明显是mac系统的问题，并且我的mac电脑是老版本 也无法继续升级了，只好尝试其他办法。
本来以为Flutter 环境很好搞 但由于我环境老旧，上述EI CAPITAN系统兼容性的问题费了我至少两周周末的时间，期间分别按照Flutter 官方、Dart降级来规避，结果发现都无法解决问题。
-
Flutter官方
-
stackoverflow.com/questions/6… 这是一个stackover的问题 么有答案。
-
Dart降级
-
dartsim.github.io/install\_da… 尝试用源码编译 但不知道如何设置Dart sdk 和Flutter的关系 故放弃。
-
dart.dev/get-dart 尝试降级无果。
-
brew install --build-from-source dart 尝试本地由源码编译 也无效。
所以回到了原点，只能采取Flutter降级的方式来规避。尝试了3.1.0，2.10.5，1.22.6三个版本才最终ok。
降级的方法是
-
使用git clone的方式 使用flutter 可参考此篇文档 github.com/flutter/flu…
-
查找flutter工程的tag github.com/flutter/flu…
-
git fetch origin $yourtaggit checkout -b $yourbranchname $yourtag
TIPS：
- 不可描述问题
在中国的话，由于众所周知的原因，必须配置下源PUB_HOSTED_URL & FLUTTER_STORAGE_BASE_URL
具体地点可以从 flutter.cn/community/c… 最终我选用的清华大学源头
export PUB_HOSTED_URL=https://mirrors.tuna.tsinghua.edu.cn/dart-pub
$ export FLUTTER_STORAGE_BASE_URL=https://mirrors.tuna.tsinghua.edu.cn/flutter
- 环境描述
Mac OS系统 EI Capitan（10.11.6 (15G22010)）
