Flutter `颤振医生`报告错误`安卓工具链-为安卓设备开发`

我在Mac中运行

flatter doctor

： 下面是一个问题：

$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.12.13+hotfix.5, on Mac OS X 10.14 18A391, locale
    zh-Hans-CN)
[✗] Android toolchain - develop for Android devices
    ✗ Unable to locate Android SDK.
      Install Android Studio from:
      https://developer.android.com/studio/index.html
      On first launch it will assist you in installing the Android SDK
      components.
      (or visit https://flutter.dev/setup/#android-setup for detailed
      instructions).
      If the Android SDK has been installed to a custom location, set
      ANDROID_HOME to that location.
      You may also want to add it to your PATH environment variable.

但是我已经在我的Mac上安装了Android SDK，路径是

/Users/delo/software/Android SDK macosx

在问这个问题之前，我必须在我的

/etc/path.d/android sdk

文件中添加

/Users/delo/software/android sdk macosx

，并将

路径添加到android sdk/tools

和

路径添加到android sdk/platform tools

但这个问题仍然存在

EDIT-01

这是echo$路径：

/Library/Frameworks/Python.framework/Versions/3.5/bin:/Users/delo/.rvm/gems/ruby-2.3.3/bin:/Users/delo/.rvm/gems/ruby-2.3.3@global/bin:/Users/delo/.rvm/rubies/ruby-2.3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/VMware Fusion.app/Contents/Public:/Users/delo/software/android-sdk-macosx:/usr/local/share/dotnet:/opt/X11/bin:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Wireshark.app/Contents/MacOS:/opt/local/bin:/usr/local/mysql/bin:/usr/local/Cellar/go/1.7.6/bin:/Users/delo/.rvm/bin:/usr/local/sbin:/Users/delo/software/android-sdk-macosx/tools:/Users/delo/software/android-sdk-macosx/platform-tools

我看到你的$PATH已经添加了ANDROID SDK路径及其

工具

和

平台工具

路径，但是没有配置颤振路径，但是你仍然可以运行

颤振医生

命令，应该有复制错误

在您的情况下，必须存在

ANDROID\u HOME

变量配置错误

你应该遵循正确的方法：

附加

export PATH=/path/to/your/flutter/bin:$PATH
export ANDROID_HOME="/path/to/your/android-sdk"
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

到

---

然后您只需

source~/.bash_profile

就可以在此处发布调用

echo$PATH

的结果。请检查。将最后一个属性

/Users/delo/software/android sdk macosx/platform toolsdelo

更改为

/Users/delo/software/android sdk macosx/platform tools

它是一个多副本，它是

/Users/delo/software/android sdk macosx/platform tools

。尝试设置安卓主页
