1 下載 Flutter SDK
https://flutter.dev/docs/development/tools/sdk/releases?tab=macos
推薦下載Stable channel, 即穩(wěn)定版
2 解壓SDK
把下載好的 Flutter SDK 隨便解壓到你想安裝Sdk的目錄, 比如
查看當(dāng)前渠道
flutter channel
可使用以下命令切換渠道
flutter channel master
flutter upgrade
如果遇到報(bào)錯(cuò)
git: Aborting
Switching channels failed with error code 1.
cd 到flutter安裝目錄, 執(zhí)行
git checkout .
然后重新執(zhí)行
flutter channel master
flutter upgrade
可能中間會(huì)失敗幾次, 多試幾次就可以了
3 安裝Dart
Dart官網(wǎng) https://dart.dev/get-dart
安裝Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
安裝dart
brew tap dart-lang/dart
brew install dart
如果報(bào)錯(cuò)
Error: An exception occurred within a child process: DownloadError: Failed to download resource "dart" Download failed: https://storage.googleapis.com/dart-archive/channels/stable/release/2.7.2/sdk/dartsdk-macos-x64-release.zip
解決方法
根據(jù)報(bào)錯(cuò)里面的地址, 手動(dòng)下載, 然后解壓放到
/usr/local/Homebrew/dart-sdk
4 配置環(huán)境變量
把 Flutter和Dart安裝目錄的 bin 目錄配置到環(huán)境變量，然后把 Flutter國內(nèi)鏡像也配置到環(huán)境變量里面
vim ~/.bash_profile
添加以下內(nèi)容
# >>> flutter init >>>
export PATH=~/Development/flutter/bin:$PATH
export FLUTTER_ROOT=~/Development/flutter
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# >>> flutter init >>>
# >>> dart init >>>
export DART_HOME=~/Development/flutter/bin/cache/dart-sdk/bin
export PATH="${DART_HOME}:${PATH}"
# >>> dart init >>>
注: ~/Development/flutter是步驟2中解壓的SDK的存放路徑
使內(nèi)容生效
source ~/.bash_profile
輸入
flutter -h
如果能出來一些命令說明 flutter sdk 配置成功。
注意如果配置完成后輸入 flutter -h 告訴你 flutter 不是內(nèi)置命令之類的錯(cuò)誤的話，可能 sdk 沒有配置成功菇肃，也可能 sdk 下載的時(shí)候沒有下載全
5 分別執(zhí)行下面命令
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
brew update
brew install --HEAD libusbmuxd
brew link libusbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
brew install ios-deploy
brew install cocoapods
pod setup
可能在運(yùn)行 brew install --HEAD libimobiledevice 會(huì)報(bào)錯(cuò),多試幾次就成功了--__--||, 如果還是不成功, 可以換成下面的命令
brew install libimobiledevice
6 安裝Android SDK
可以自己下載SDK安裝, 也可以通過Android Studio安裝, 這里推薦用Android Studio來安裝, 后續(xù)也方便查看項(xiàng)目代碼
Android Studio下載地址 https://developer.android.google.cn/studio/
安裝完后, 打開, 根據(jù)提示安裝好相應(yīng)的SDK即可
7 檢測(cè)是否配置完成
flutter doctor
如果出現(xiàn)下圖, 就是配置成功
如果出現(xiàn)報(bào)錯(cuò) Android sdkmanager not found. Update to the latest Android SDK and ensure that the cmdline-tools are installed to resolve this.
打開Android Studio -> Preference -> 搜索框搜索SDK -> Android SDK -> SDK Tools -> 勾選Android SDK Command-line Tools(latest) -> OK
等待下載完即可, 然后重新執(zhí)行flutter doctor執(zhí)行檢驗(yàn)
如果安裝的Flutter SDK是2.10, 則會(huì)報(bào)錯(cuò) HTTP Host Availability HTTP host https://maven.google.com/ is not reachable. Reason: An error occurred while checking the HTTP host: Operation timed out
解決方法
1 找到flutter sdk的文件目錄，打開flutter\packages\flutter_tools\lib\src\http_host_validator.dart
2 將https://maven.google.com/修改為https://dl.google.com/dl/android/maven2/
3 關(guān)閉終端牍戚，重新打開終端
4 去到flutter sdk的文件目錄, 找到bin目錄仿耽，刪除cache文件夾
5 在終端重新運(yùn)行flutter doctor, 問題解決。
8 命令行工具生成 Flutter 項(xiàng)目
flutter create flutterdemo
9 修改 Flutter Sdk 目錄的權(quán)限以及項(xiàng)目的權(quán)限
sudo chmod -R 777 /Users/darren/Development/flutter (Flutter SDK 目錄)
sudo chmod -R 777 /Users/darren/Desktop/VS Code projects/Flutter/flutterdemo (項(xiàng)目目錄)
10 運(yùn)行iOS項(xiàng)目
注: 打開項(xiàng)目之前一定得先修改權(quán)限
Xcode打開項(xiàng)目目錄 -> ios -> Runner.xcodeproj -> Command + R 運(yùn)行
11 VS Code 中安裝 Flutter 插件 Dart 插件
安裝VS Code https://code.visualstudio.com/
設(shè)置 -> Extensions -> 搜索并安裝 Flutter插件 Flutter Widget Snippets插件 Dart插件
12 用VS Code運(yùn)行
打開 flutter 項(xiàng)目進(jìn)行開發(fā), 執(zhí)行
flutter run
