在MacOS上安装Flutter环境

系统需求

  • 操作系统: MacOS(64位)
  • 磁盘空间: 700MB(不包括IDE工具的磁盘占用)
  • 必备工具: 需要以下命令行工具的支持
    • bash,mkdir,rm,git,curl,unzip,which

获取FLutter SDK

  1. 跟随以下链接下载到最新的Beta版本的Flutter SDK(寻找其他发布版本,或者一些旧的版本编译,请查看SDK归档页面。):

  2. 解压这个文件在你想要的目录,例如:

    $ cd ~/Study
    $ unzip ~/Desktop/flutter_macos_v0.5.1-beta.zip
    
    1. 添加flutter到你环境变量path: bash $ export PATH=`pwd`/flutter/bin:$PATH

注:该方法只对当前终端进程有效,需要永久生效建议修改PATH文件

执行以上命令以后,就可以在命令行直接输入flutter命令了,运行flutter doctor来完成安装。得到系统需要更新,这里再次输入flutter upgrade

执行完后会自动执行flutter doctor,会检测当前系统缺少的依赖环境。如下所示:

 [✓] Flutter (Channel beta, v0.5.1, on Mac OS X 10.13.5 17F77, locale en-CN)
[!] Android toolchain - develop for Android devices (Android SDK 27.0.3)
    ! Some Android licenses not accepted.  To resolve this, run: flutter doctor --android-licenses
[!] iOS toolchain - develop for iOS devices (Xcode 9.4.1)
    ✗ Missing Xcode dependency: Python module "six".
      Install via 'pip install six' or 'sudo easy_install six'.
    ✗ libimobiledevice and ideviceinstaller are not installed. To install, run:
        brew install --HEAD libimobiledevice
        brew install ideviceinstaller
    ✗ ios-deploy not installed. To install:
        brew install ios-deploy
    ✗ CocoaPods not installed.
        CocoaPods is used to retrieve the iOS platform side's plugin code that responds to your plugin usage on the Dart side.
        Without resolving iOS dependencies with CocoaPods, plugins will not work on iOS.
        For more info, see https://flutter.io/platform-plugins
      To install:
        brew install cocoapods
        pod setup
[✓] Android Studio (version 3.1)

明显代表是满足依赖,代表不满足依赖,!是警告。 每行后面都包含了解决问题的方式和方法。

根据提示方法解决依赖不足的问题。如下是解决后flutter doctor所提供的报告:

Doctor summary (to see all details, run flutter doctor -v):

到此环境安装已结束。可以在Android Studio新建工程并开始体验热更新。
