我运行npx react-native run-android，得到这个
这似乎是问题所在，它在~/中寻找平台工具，而不是在~/Android/Sdk中
java.io.io异常：无法运行程序"home/u/平台工具/adb"：error=2，没有这样的文件或目录`
你可以忽略这一点，如果我不添加更多文本，堆栈不会让我发布这一消息，但我认为这已经是一个很好的解释

检查$ANDROID_HOME变量指向的位置。
echo $ANDROID_HOME
If必须等于Android/Sdk的路径，通常在~/Android/Sdk
一个解决方案，如果你知道变量ANDROID_HOME在哪里(可能是~/.bashrc，~/.profile(：
转到你有varANDROID_HOME的文件并编辑它，使其看起来像这个
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
在您更改它们之后，执行source .bashrc或source {whatever file they're on}，它应该可以工作(它在您执行的终端上工作，它，在您希望它工作的任何终端中执行，如果它在.bashrc上，它将在下次重新启动时工作，而不执行源代码(
如果Android安装在~/中，它就是这样做的(你可以通过执行cd进行检查，然后ls、Android应该出现，如果没有，则将$HOME更改为你安装它的方向(。
如果您根本没有这些变量：只需打开~/.bashrc并将它们添加到文件中。按照前面的解释做同样的事情。
是的，就是这样。如果有人把它翻译成Windows和Mac的方式，我将不胜感激。
