MAC上Flutter环境搭建记录

官网

配置国内镜像

• 配置命令

  export PUB_HOSTED_URL=pub.flutter-io.cn export FLUTTER_STORAGE_BASE_URL=storage.flutter-io.cn

下载安装Flutter

• 下载Flutter SDK，解压配置即可；
• 通过 git 方式获取（推荐此方式）：

"git clone https://github.com/flutter/flutter.git -b stable"

• 遇到问题：SSL_ERROR_SYSCALL in connection to github.com:443

   一般为网络问题或者代理问题

fatal: unable to access 'https://github.com/flutter/flutter.git/': LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443

• 解决方案：分为http和https

  git config --global --unset http.proxy git config --global --unset https.proxy

设置完以后重启终端！

 将 Flutter 添加全局环境变量

• 打开(或创建) .bash_profile. 我在 本用户名 文件夹下创建

参考flutter中文网教程：打开(或创建) $HOME/.bash_profile. 文件路径和文件名可能在您的机器上不同.

先 open .bash_profile 查看是否有.bash_profile  文件，如无 touch .bash_profile

添加如下配置

export PUB_HOSTED_URL=https://pub.flutter-io.cn //国内用户需要设置
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn //国内用户需要设置
export PATH=PATH_TO_FLUTTER_GIT_DIRECTORY/flutter/bin:$PATH

• 注意：PATH_TO_FLUTTER_GIT_DIRECTORY 为你flutter的路径，比如“~/document/code”

  #我的配置如下 export PATH=/Users/用户名文件夹/flutter/bin:$PATH

• 随后，通过 which flutter 验证已配置的 Flutter 是否可用：

  which flutter

 通过 flutter doctor 验证当前 Flutter 开发环境是否完善

flutter doctor

• 遇到问题：Failed to retrieve the Dart SDK

解决办法：切换了下VPN的服务器节点，就好了。猜测是网络不好！

重新运行之后正常:如图

环境搭建完成，还差 Android Studio 需要安装和配置。
