为什么 ns doctor android 有问题？

Question

✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ The Android SDK is installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Getting NativeScript components versions information...
✔ Component nativescript has 8.1.4 version and is up to date.
✔ Component @nativescript/core has 8.1.5 version and is up to date.
✖ Component @nativescript/android is not installed.

正如你在最后一行看到的，我的@nativescript/android 没有安装。 我安装了好几次。

还有当我

ns run android

我有这个

Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.

Unable to apply changes on device: emulator-5554. Error is: Command ./gradlew failed with exit code 1.

Answer 1

@nativescript/android 需要位于 devDependency 中：

使用它从依赖项中删除：

npm r @nativescript/android

然后将其添加到 devDependencies 中：

npm i -D @nativescript/android

Answer 2

在 NativeScript 8.2.3 中，

ns doctor android

给出以下输出：
ns doctor android 输出

所以我也安装了Android SDK 28（也安装了33仍然有这个问题）。此外，该消息还警告@nativescript/android 的更新可用。

将 @nativescript/android 从 8.1.1 更新到 8.2.2 解决了该问题：

npm i @nativescript/android@latest

。

Answer 3

退出终端并重新打开，它给了我相同的失败结果，但是一旦我退出并重新打开，然后运行

ns doctor android

，一切都已正确设置。
