React Native adb reverse ENOENT [英] React Native adb reverse ENOENT

问题描述

我正在尝试让 React-Native 与 Android V4.2.2 (Genymotion) 一起使用，但我无法在模拟器上测试该应用程序.当我运行 react-native run-android 时，出现此错误 Could not run adb reverse: spawnSync

这是一个日志

解决方案

我遇到了同样的问题.我再次更新了我的 ANDROID_HOME 环境变量，它对我有用.

按照这个React-原生 android-setup 文档

例如:

export ANDROID_HOME=~/Library/Android/sdk

Windows:

set ANDROID_HOME=c:/Users/whoever/AppData/Local/Android/Sdk

ma​​cOS Mojave 及更早版本或 bash 用户:

1 - 打开您的 bash 配置文件:

打开 .bash_profile

将此添加到您的 bash_profile:

 export ANDROID_SDK=/Users//Library/Android/sdkexport PATH=/Users//Library/Android/sdk/platform-tools:$PATH

保存并关闭

编译您的更改

source ~/.bash_profile

对于 macOS Catalina 和 zsh 用户:

从 macOS Catalina 开始，您的 Mac 使用 zsh 作为默认登录 shell 和交互式 shell.您也可以将 zsh 设为早期版本的 macOS 中的默认值.

在您的 Mac 上:

打开您的 .zshrc 文件:

打开 ~/.zshrc

如果 .zshrc 文件不存在，您需要使用 touch & 创建一个打开.

touch ~/.zshrc

将此添加到您的 .zshrc 文件

export ANDROID_SDK=/Users//Library/Android/sdkexport PATH=/Users//Library/Android/sdk/platform-tools:$PATH

保存并关闭

编译您的更改

source ~/.zshrc

更新了 macOS Catalina 和 zsh 用户的答案.

I am trying to get React-Native to work with Android V4.2.2 (Genymotion) but I am unable to test the app on the Emulator. When I ran react-native run-android, I get this error Could not run adb reverse: spawnSync

Here is a log

JS server already running.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> The SDK directory '~/Library/Android/sdk' does not exist.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

NOTE: In the log it saids SDK directory does not exist, I have double check that I do have the SDK installed in that directory.

I found my android emulator when executing adb devices

I have tried the following steps from Stack Overflow post, but still no luck https://stackoverflow.com/a/38536290/4540216

解决方案

I got the same issue. I updated my ANDROID_HOME env variable again it worked for me.

Follow this React-native android-setup documentation

ex:

export ANDROID_HOME=~/Library/Android/sdk

Windows:

set ANDROID_HOME=c:/Users/whoever/AppData/Local/Android/Sdk

macOS Mojave and earlier or bash users:

1 - Open your bash profile:

open .bash_profile

Add this to your bash_profile:

 export ANDROID_SDK=/Users/<your_computer_name>/Library/Android/sdk
 export PATH=/Users/<your_computer_name>/Library/Android/sdk/platform-tools:$PATH

Save and close

Compile your changes

source ~/.bash_profile

For macOS Catalina and zsh users:

Starting with macOS Catalina, your Mac uses zsh as the default login shell and interactive shell. You can make zsh the default in earlier versions of macOS as well.

On your Mac:

Open your .zshrc file:

open ~/.zshrc

If .zshrc file not exist, you need to create one using touch & open.

touch ~/.zshrc

Add this to your .zshrc file

export ANDROID_SDK=/Users/<your_computer_name>/Library/Android/sdk
export PATH=/Users/<your_computer_name>/Library/Android/sdk/platform-tools:$PATH

Save and close

Compile your changes

source ~/.zshrc

Edit: Updated answer for macOS Catalina and zsh users.
