Android SDK 未构建

Question

我正在使用 ubuntu 18.04，我正在学习 react-native。

我没有安装 Android Studio，而是安装了 Genymotion 作为我的 android 模拟器用于测试，并使用 sudo apt-get install android-sdk 安装了 Android SDK

安装react和react native工具后，我创建了一个新的react-native项目，并尝试在不接触任何代码的情况下运行它，但出现以下错误

$ react-native run-android

我可以通过从在他们的 ubuntu 上安装 Android Studio 的人那里复制文件来完成这个 android-sdk 安装，还是我应该完全安装 Android Studio 并更改我的路径？

Answer 1

是的，您也可以从谷歌的网站下载它们，或者在下载“一体化”android studio 包时重新安装 sdk。还要查看文件夹(如果存在)/usr/lib/android-sdk-linux/tools/bin。您有错误/未完成的安装。如果某人的计算机运行 deb linux 发行版并且具有相似的处理器(例如，你们都使用 Intel)，则可以只复制文件。
