【中文标题】Ionic 找不到 android_sdk_root，无法在手机上构建应用程序【英文标题】：Ionic Failed to find android_sdk_root, cannot build app on phone 【发布时间】：2021-10-21 05:59:30 【问题描述】：

当我在 vscode 终端中提示 ionic cordova build android 时，过了一会儿它给了我：

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=undefined (DEPRECATED)
Failed to find 'ANDROID_SDK_ROOT' environment variable. Try setting it manually.
Failed to find 'android' command in your 'PATH'. Try update your 'PATH' to include path to valid SDK directory.
[ERROR] An error occurred while running subprocess cordova.

        cordova.cmd build android exited with exit code 1.

        Re-running this command with the --verbose flag may provide more
        information.

我检查了我的路径，我认为没问题？

我可以得到一些帮助吗？

我想在手机上测试我的应用。我的手机已经在 Xamarin 上运行。

编辑：现在错误不同了：（直接用verbose）

我在这台计算机上安装了 Android Studio，但从未在该用户上执行过它。我应该打开它吗？ [1]：https://i.stack.imgur.com/BO5wx.png [2]：https://i.stack.imgur.com/qQ4VE.png

【问题讨论】：

您能否将C:\Program Files (x86)\Android\android-sdk\tools 添加到Path 变量中。然后在使用--verbose 标志重新启动终端后尝试构建命令。我用 --verbose 标志编辑了问题并将两个路径都更改为 C:\Program Files (x86)\Android\android-sdk\tools “将两条路径都更改为..”是什么意思？我在环境变量的 C:\Program Files (x86)\Android\android-sdk 上有 ANDROID_SDK_ROOT 和 ANDROID_HOME。见图片。我把那些改成了你写给我的。请按照您的 android sdk 路径 (C:\Program Files (x86)\Android\android-sdk) 保留 ANDROID_SDK_ROOT 和 ANDROID_HOME。现在将 C:\Program Files (x86)\Android\android-sdk\tools 添加到 Path 变量中（通过选择 Path 并单击 env 变量中的 Edit > New） 【参考方案1】：

我遵循了 Akshaya Jeevan 的提示和 documentation
