我无法运行我的第一个应用程序,因为adb’未被识别为内部或外部命令,可 *** 作程序或批处理文件而出现错误.

我检查了androID sdk-> platform-tools->我可以在那里看到adb.exe.

构建成功但在运行时出错.下面是我的cmd提示符

我没有使用模拟器,使用自己的移动设备.应用程序在我的设备中启动,但我看到的只是一个白色的空白屏幕.我按照官方网站上的说法正确遵循了所有说明.

谢谢.

解决方法 我找到了解决方案.

您所要做的就是在系统变量中添加adb路径.

复制adb位置,然后转到Controlpanel-> System-> Advnaced System Settings-> Environment Variables->在系统变量下,您将找到PATH变量,首先选择并单击Edit,然后单击New并粘贴您的adb路径,现在单击确定.多数民众赞成解决问题.

现在重新启动命令提示符,并运行react-native run-androID.有用：)

希望这有助于某人.谢谢你查看我的问题.
