【问题描述】：

我在我的 Mac 上运行 flutter doctor：下面出现一个问题：

$ 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这个路径/Users/delo/software/android-sdk-macosx安装了Android SDK。

在问这个问题之前，我已经关注this post 在我的/etc/paths.d/android-sdk 文件中添加/Users/delo/software/android-sdk-macosx，this post 添加path-to-android-sdk/tools 和path-to-android-sdk/platform-tools。

但还是有这个问题。

EDIT-01

这是echo $PATH：

/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

【问题讨论】：

可以把调用echo $PATH的结果贴在这里
更新了它。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ANDROID_HOME

标签： flutter android-sdk-2.3

【解决方案1】：

我看到你的$PATH已经添加了ANDROID SDK PATH及其tools和platform-tools PATH，但是没有配置flutter PATH，但是你仍然可以运行flutter doctor命令，应该有复制错误。

在你的情况下，一定有ANDROID_HOME变量配置错误，

你应该遵循正确的方法：

追加

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

那么你只需source ~/.bash_profile。
