Mac 配置flutter

一、推薦去官網下載，速度並不慢，網址：

https://flutter.io/setup-macos/

配置環境變量,這裏筆者使用命令行：

vim ~/.bash_profile

添加環境配置

export PATH=/你的flutter文件夾所在位置/flutter/bin:$PATH

保存一下，注意若是這個文件不存在，那麼就新建一個。保存完畢以後運行命令:

source ~/.bash_profile

這個時候應該能運行flutter命令了，咱們運行命令行：

flutter -h

看起來是如此的簡單：可是坑仍是不少的
坑一、.bash_profile文件根本不存在 建立一個

touch .bash_profile

添加以下配置

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=/Users/ruihe/Downloads/flutter/bin:$PATH

坑二、
MacBook-Pro:~ xxxx$ flutter -h
-bash: flutter: command not found
下載下來以後把文件複製到其它裏面去了 運行source ~/.bash_profile一直抱這個錯，糾結了很久，最後從新下載了一根直接把這個下載的路徑/Users/xxxx/Downloads/設置了進去，
xxxxxx$ open ~/.bash_profile
xxxxxx$ source .bash_profile
xxxxxx$ source ~/.bash_profile
主要不知道2和3那個是對的，因此一塊兒運行了一下
坑三、

$ flutter doctor
