Java找不到‘/platform-tools/亚行’(使用react原生构建应用程序)

Question

我运行npx react-native run-android并得到这个

这似乎是问题所在，它正在寻找~/中的平台工具，而不是~/Android/Sdk中的平台工具

java.io.IOException:无法运行程序“/home/u/platform/adb”：error=2，没有这样的文件或目录

您可以忽略这一点，如果我不添加更多的文本，堆栈不会让我发布这个，但是我认为这已经是一个很好的解释了

Answer 1

检查$ANDROID_HOME变量指向的位置。

echo $ANDROID_HOME

如果必须等于Android/Sdk的路径，通常在~/Android/Sdk处

一个解决方案，如果您知道变量ANDROID_HOME在哪里(可能是~/.bashrc，~/.profile)：

转到您拥有var ANDROID_HOME的文件并编辑它，如下所示

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}操作，并且它应该可以工作(它在您所做的终端上工作，它在任何您希望它工作的终端上运行，如果它在.bashrc上运行，那么下次在不执行源代码的情况下重新启动时它就会工作)

如果在~/中安装了Android，就会这样做(您可以通过执行cd来检查，然后ls，如果没有，Android应该会出现，更改$HOME以确定安装位置)。

如果根本没有这些变量:只需打开~/.bashrc并将它们添加到文件中即可。和之前解释过的一样。

对，就是这样。如果有人把这个翻译成Windows和Mac的话我会很感激的。
