npx react-native run-android 不起作用 - “java.io.IOException：文件名、目录名或卷标语法不正确”

Question

最近刚刚退出博览会，我正在尝试在 android 设备上运行我的应用程序。我按照说明操作（希望是正确的），但是当我尝试运行我的应用程序时，我不断收到此错误：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.0.1/userguide/command_line_interface.html#sec:command_line_warnings

* What went wrong:

谢谢您的帮助！

Answer 1

我为这个问题苦苦挣扎了 3 个小时，但没有任何效果。

我设法通过删除local.properties文件中的引用来解决我的问题：

sdk.dir = "C:\\Users\\<USER>\\AppData\\Local\\Android\\Sdk"

到

sdk.dir = C:\\Users\\<USER>\\AppData\\Local\\Android\\Sdk

Answer 2

我能够通过改变来解决这个问题

sdk.dir =   C:\Users\mob\AppData\Local\Android\Sdk

到

sdk.dir =   C:\\Users\\mob\\AppData\\Local\\Android\\Sdk

Answer 3

我在 Windows 上遇到了同样的问题，我的问题出在 Gradlelocal.properties文件上。它包含以下内容：

org.gradle.java.home=C:\Program Files\Java\jdk-15.0.1
sdk.dir=C:\Users\user\AppData\Local\Android\Sdk

问题可能出在 Windows 反斜杠 ( \) 上。有效的是逃避它：

org.gradle.java.home="C:\\Program Files\\Java\\jdk-15.0.1"
sdk.dir=C:\\Users\\user\\AppData\\Local\\Android\\Sdk

Answer 4

我通过以下设置解决了问题：

在我的脚本末尾添加以下命令android > gradlew：

yes | $ANDROID_HOME/tools/bin/sdkmanager "platforms;android-28"

yes | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;28.0.3"

并在android > gradle > wrapper > gradle-wrapper.properties变化中

distributionUrl=https://services.gradle.org/distributions/gradle-6.{any}-all.zip

到

distributionUrl=https://services.gradle.org/distributions/gradle-6.3-all.zip

并检查节点版本是否node v12或以上，然后更新JDK v{any}到JDK v14.

也在android > build.gradle变化中

buildToolsVersion: {any}到buildToolsVersion: 28.0.3

在更改 buildToolsVersion 之前检查您是否已安装v28.0.3。如果没有那么没问题上面两个命令会自动安装它。

最后一件事是检查您是否拥有该local.properties文件。如果它存在于android文件夹下，请检查您的 sdk 路径是否正确。如果不存在，则在android文件夹下创建一个名为的新文件local.properties，并在该文件下写入以下命令：

sdk.dir=Your SDK folder path

希望经过以下设置后您可以开始跑步了npx react-native run-android

这对我有用！
