mac配置flutter踩坑118kj开奖现场

按照官网的教程:

一步步来,到flutter doctor报错,根据错误提示修改错误。

我的错误记录

用Android studio新建flutter项目报如下错误

error installing flutter null returned 1

Android studio在创建flutter项目选择SDK path时,提示的错误。

其中SDK path就是从官网下载的SDK,flutter文件夹地址。当flutter doctor命令没有验证通过时,选择SDK path会报这个错误。需要执行flutter doctor查看的报错

 ✗ 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

依次执行上述提示的brew命令,再次flutter doctor

当mac插上手机设备报如下错误:

Unhandled exception:Exception: idevice_id returned an error:#0 IMobileDevice.getInfoForDevice (package:flutter_tools/src/ios/mac.dart:122:9)<asynchronous suspension>#1 IOSDevice.getAttachedDevices (package:flutter_tools/src/ios/devices.dart:152:53)<asynchronous suspension>#2 IOSDevices.pollingGetDevices (package:flutter_tools/src/ios/devices.dart:112:57)#3 PollingDeviceDiscovery.devices (package:flutter_tools/src/device.dart:163:52)<asynchronous suspension>#4 DeviceManager.getAllConnectedDevices (package:flutter_tools/src/device.dart:91:46)<asynchronous suspension>#5 DeviceValidator.validate (package:flutter_tools/src/doctor.dart:677:54)<asynchronous suspension>#6 Doctor.startValidatorTasks (package:flutter_tools/src/doctor.dart:107:52)#7 Doctor.diagnose (package:flutter_tools/src/doctor.dart:174:41)#8 _AsyncAwaitCompleter.start (dart:async/runtime/libasync_patch.dart:49:6)#9 Doctor.diagnose (package:flutter_tools/src/doctor.dart:164:24)#10 DoctorCommand.runCommand (package:flutter_tools/src/commands/doctor.dart:29:39)#11 _AsyncAwaitCompleter.start (dart:async/runtime/libasync_patch.dart:49:6)#12 DoctorCommand.runCommand (package:flutter_tools/src/commands/doctor.dart:28:42)#13 FlutterCommand.verifyThenRunCommand (package:flutter_tools/src/runner/flutter_command.dart:383:18)#14 _asyncThenWrapperHelper.<anonymous closure> (dart:async/runtime/libasync_patch.dart:77:64)#15 _rootRunUnary (dart:async/zone.dart:1132:38)#16 _CustomZone.runUnary (dart:async/zone.dart:1029:19)#17 _FutureListener.handleValue (dart:async/future_impl.dart:129:18)#18 Future._propagateToListeners.handleValueCallback (dart:async/future_impl.dart:642:45)#19 Future._propagateToListeners (dart:async/future_impl.dart:671:32)#20 Future._complete (dart:async/future_impl.dart:476:7)#21 _SyncCompleter.complete (dart:async/future_impl.dart:51:12)#22 _AsyncAwaitCompleter.complete.<anonymous closure> (dart:async/runtime/libasync_patch.dart:33:20)#23 _rootRun (dart:async/zone.dart:1124:13)#24 _CustomZone.run (dart:async/zone.dart:1021:19)#25 _CustomZone.bindCallback.<anonymous closure> (dart:async/zone.dart:947:23)#26 _microtaskLoop (dart:async/schedule_microtask.dart:41:21)#27 _startMicrotaskLoop (dart:async/schedule_microtask.dart:50:5)#28 _runPendingImmediateCallback (dart:isolate/runtime/libisolate_patch.dart:115:13)#29 _RawReceivePortImpl._handleMessage (dart:isolate/runtime/libisolate_patch.dart:172:5)

其实是上面的brew命令有问题,解决办法:

brew updatebrew uninstall --ignore-dependencies libimobiledevicebrew uninstall --ignore-dependencies usbmuxdbrew install --HEAD usbmuxdbrew unlink usbmuxdbrew link usbmuxdbrew install --HEAD libimobiledevice

再次flutter doctor

这次只有一个错误

[!] Android toolchain - develop for Android devices (Android SDK version 28.0.3) ✗ Android license status unknown

执行下面命令,来接受安卓许可证协议

flutter doctor --android-licenses

报错

A newer version of the Android SDK is required. To update, run:/Users/duan/Library/Android/sdk/tools/bin/sdkmanager --update

解决方法是使用SDKMANAGER_OPTS环境变量

export SDKMANAGER_OPTS="--add-modules java.se.ee"

之后再执行

flutter doctor --android-licenses

依次y回车,来接收许可证

再次flutter doctor,结果:

[✓] Flutter (Channel stable, v1.2.1, on Mac OS X 10.14.2 18C54, locale zh-Hans-CN)[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)[✓] iOS toolchain - develop for iOS devices (Xcode 10.1)[✓] Android Studio (version 3.3)[✓] VS Code (version 1.31.1)[✓] Connected device (2 available)• No issues found!

成功~

最后记录下运行后的错误处理:

ERROR: Could not connect to lockdownd, error code -17

这是设备和计算机没有建立信任关系,手机和电脑互相信任就可以了
