Flutter安装使用要注意的细节
1、修改PATH
$ pwd // /Users/vincentzheng/Documents
$ vim ~/.bash_profile
$ export PATH**=**$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin
2、安装CocoaPods报错

解决方案：
（1）修改ruby源到https://ruby.taobao.org/
$ gem sources -l
/* output
*** CURRENT SOURCES ***
https://rubygems.org/
*/
$ gem sources --add https://gems.ruby-china.com/ --remove [https://rubygems.org/](https://rubygems.org/)
$ gem sources -l
/* output
*** CURRENT SOURCES ***
https://gems.ruby-china.com/
*/
$ sudo gem update --system
$ sudo gem install -n /usr/local/bin cocoapods
$ pod setup
3、热加载必须关掉VPN，否则识别不了localhost
