macOS系统上flutter安装与环境配置

添加国内镜像

本地目录~/.bash_profile内，添加flutter国内镜像（command+shift+.查看隐藏文件，如没有.bash_profile文件，则新建一个）

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

获取flutter SDK

1.下载flutter，有两种方式
官网地址： https://flutter.dev/docs/development/tools/sdk/releases?tab=macos#macos github地址： https://github.com/flutter/flutter/releases

2.解压安装包到你想安装的目录，如：

cd ~/development
unzip ~/Downloads/flutter_macos_1.22.4-stable.zip

3.添加flutter相关工具到path中：

针对当前命令行窗口设置PATH环境变量

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

永久将Flutter添加到PATH中(推荐)，在~/.bash_profile内添加环境变量

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“~/development”

export PATH=~/development/flutter/bin:$PATH

4.运行 source $HOME/.bash_profile刷新当前终端窗口
5.运行 flutter doctor，检测flutter SKD是否安装完成，同时查看其它安装项

flutter doctor

获取Android SDK

1.安装Android studio，安装过程中自动安装Android SDK
官网地址：https://developer.android.com/studio/index.html Android studio中文社区地址：http://www.android-studio.org

2.在~/.bash_profile内添加Android SDK的环境变量

export ANDROID_HOME="/Users/用户名/Library/Android/sdk"

注意：android sdk目录，“用户名”替换为你自己的即可
3.首次安装同意Android协议

flutter doctor --Android-licenses

4.安装Android studio plugins，安装flutter和dart插件
5.运行 flutter doctor，检测Android SKD是否安装完成

安装xcode

1.安装xcode
官网地址：https://developer.apple.com/download/

2.启动xcode，打开xcode > Preferences > locations，将Command Line Tools 设置为当前版本的xcode

3.切换路径

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

4.确保Xcode许可协议是通过打开一次Xcode或通过命令同意过了

sudo xcodebuild -license

5.运行 flutter doctor，检测xcode是否安装完成，如需安装依赖，按提示执行

flutter安装和配置过程中的一些错误处理

环境：(解决错误请注意自己的环境和版本信息)
mac 10.15.7
xcode 12.2
Command Line Tools for Xcode 12.2
Android studio 4.1

1.执行安装cocoapods时报错

sudo gem install cocoapods

错误信息：

问题目录：

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin19

问题原因：

安装需要的文件名，与自己系统内的文件名不一致

解决办法：

查看自己电脑该路径下是universal-darwin20
拷贝文件universal-darwin20，并重命名为universal-darwin19
或者执行命令，创建软连接

ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/universal-darwin20 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/universal-darwin19

2.flutter doctor提示Android studio没有安装flutter、dart插件，实际已经安装
问题原因：

在Android studio 4.1中plugin目录发生了变化

解决办法：

ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1

3.flutter项目运行卡在Running Gradle task ‘assembleDebug’
问题原因：

由于网络无法访问到Google服务引起的

镜像链接：

maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

解决办法：

找到Flutte SDK目录下的Flutter打包配置文件flutter.gradle，路径为flutter\packages\flutter_tools\gradle\flutter.gradle，或者当前项目.flutter\packages\flutter_tools\gradle\flutter.gradle
修改Flutter项目下的.android下的build.gradle，路径为.android/build.gradle
