一. 如果你是download的release包，运行flutter doctor会报如下错误：
Error: The Flutter directory is not a clone of the GitHub project.
The flutter tool requires Git in order to operate properly;
to set up Flutter, run the following command:
git clone -b beta https://github.com/flutter/flutter.git
解决方案：
- 在flutter目录执行
git init。不推荐 -
git clone https://github.com/flutter/flutter.git或者按官方推荐git clone -b beta https://github.com/flutter/flutter.git使用beta分支。
二、安装中文版教程中安装iOS设备的工具时会报错：
checking pkg-config is at least version 0.9.0... yes checking for libusbmuxd >= 1.1.0... no configure: error: Package requirements (libusbmuxd >= 1.1.0) were not met:
Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10
解决方案在英文版中已经提供：
brew update
# The following two steps are a temporary workaround to https://github.com/flutter/flutter/issues/22595
brew install --HEAD usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller ios-deploy cocoapods
pod setup
所以还是推荐大家去看英文原版教程，更新比较及时。
三、最新的Android Studio Preview版本不支持flutter，建议使用正式版。
