安裝之前的環(huán)境：

pod: 1.5.3
xcode : 10.1

1. 獲取Flutter SDK

通過官網(wǎng)地址：https://flutter.io/sdk-archive/#windows 下載最新的SDK

2. 配置環(huán)境變量

進入文件.bash_profile ，如果沒有就通過命令創(chuàng)建一個 touch .bash_profile

xia:~ mac$ vim .bash_profile

在文件中加入一行

export PATH={pwd}/flutter/bin:$PATH

其中pwd是下載的flutter所在的文件路徑
例如，我的flutter下載之后放在了~/flutter路徑下，那么我的就是

export PATH=~/flutter/bin:$PATH

接下來運行source命令，更新配置

xia:~ mac$ source .bash_profile

3. 運行Flutter

執(zhí)行命令

xia:~ mac$ flutter -h

應(yīng)該會出現(xiàn)' Welcome to Flutter! '的歡迎語，具體命令輸出就不粘貼了

4. 檢查Flutter環(huán)境

執(zhí)行命令flutter doctor

xia:~ mac$ flutter doctor

此時我的窗口出現(xiàn)了下面的輸出，顯示[?][!]就是錯誤和警告的地方，接下來按照提示一步一步解決

1. 安裝Android Studio、Android SDK、Flutter插件、Dark插件

此時并未安裝Android SDK。第一步安裝Android Studio之后，啟動，會彈出一個框，點擊cancel，接下來Android Studio會自動安裝SDK。安裝好了之后，重啟Android Studio，在Android Studio-Preference-Plugins中安裝Fluuter和Dark插件

再次執(zhí)行 flutter doctor 命令

安裝了Flutter和Dark插件，還是報下邊的錯誤
? Flutter plugin not installed; this adds Flutter specific functionality.
? Dart plugin not installed; this adds Dart specific functionality.

我的解決辦法是執(zhí)行了一下

flutter doctor -v

報? Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses錯誤的話就執(zhí)行一下
flutter doctor --android-licenses就好,確認(rèn)一下協(xié)議，輸入y確認(rèn)下就行

2. 安裝iOS toolchain

這個比較簡單，按照提示步驟一步一步來

[!] iOS toolchain - develop for iOS devices (Xcode 10.1)
    ? libimobiledevice and ideviceinstaller are not installed. To install with
      Brew, run:
        brew update
        brew install --HEAD usbmuxd
        brew link usbmuxd
        brew install --HEAD libimobiledevice
        brew install ideviceinstaller

在這個過程中我安裝libimobiledevice的時候報了下邊這個錯誤,解決辦法是執(zhí)行 pod setup，然后多試幾次，多試幾次?。?！

Cloning into '/Users/mac/Library/Caches/Homebrew/libimobiledevice--git'...
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

最后再執(zhí)行 flutter doctor 輸出以下信息，說明全部安裝完畢，恭喜~
