主要參考flutter中文官方,結(jié)合自己操作過程的問題整理的這篇文章

使用鏡像

由于在國內(nèi)訪問Flutter有時可能會受到限制琳状，F(xiàn)lutter官方為中國開發(fā)者搭建了臨時鏡像，大家可以將如下環(huán)境變量加入到用戶環(huán)境變量中：

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

注意： 此鏡像為臨時鏡像，并不能保證一直可用，讀者可以參考詳情請參考 Using Flutter in China 以獲得有關(guān)鏡像服務(wù)器的最新動態(tài)。

獲取Flutter SDK

1.去Flutter官網(wǎng)下載官網(wǎng)地址 或者 去github上下載git地址
2.解壓安裝包到你想安裝的目錄，如：

cd ~/Users/#自己的賬戶名#
unzip ~/Downloads/flutter_macos_v0.5.1-beta.zip  #下載的zip文件#

3.添加flutter相關(guān)工具到path中：(在步驟2當(dāng)前路徑下)

export PATH=`pwd`/flutter/bin:$PATH

運(yùn)行 flutter doctor

1.先修復(fù)iOS toolchain 問題

[!] iOS toolchain - develop for iOS devices (Xcode 10.1)
? libimobiledevice and ideviceinstaller are not installed. To install with
Brew, run:
brew update #step1
brew install --HEAD usbmuxd #step2
brew link usbmuxd #step3
brew install --HEAD libimobiledevice #step4
brew install ideviceinstaller #step5

前三步的時候沒啥問題, 到第四步的時候死活裝不上提示:
Cloning into '/Users/chengguangfa/Library/Caches/Homebrew/libimobiledevice--git'... fatal: unable to access 'https://git.libimobiledevice.org/libimobiledevice.git/': LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to git.libimobiledevice.org:443
的錯誤SSL_ERROR_SYSCALL,
查了下資料才知道是被墻了. 掛著梯子,再次brew install --HEAD libimobiledevice, 成功!!!

bogon:flutter_Place chengguangfa$  brew install --HEAD libimobiledevice

修復(fù)完iOS toolchain的問題后, 繼續(xù)flutter doctor

其他的主要是Andriod Studio 沒安裝的問題,

安裝Android Studio

要為Android開發(fā)Flutter應(yīng)用篓足，您可以使用Mac，Windows或Linux（64位）機(jī)器.

Flutter需要安裝和配置Android Studio:

1. 下載并安裝 Android Studio.

2. 啟動Android Studio拘泞，然后執(zhí)行“Android Studio安裝向?qū)А狈兹摇＿@將安裝最新的Android SDK，Android SDK平臺工具和Android SDK構(gòu)建工具陪腌，這是Flutter為Android開發(fā)時所必需的

3. 打開android studio, 打開plugin
