Question

Appium服务器显示无法将'null'强制为有效的版本号错误。

以下是我使用过的DesiredCapabilities

DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability(MobileCapabilityType.UDID, udid);
caps.setCapability(MobileCapabilityType.NO_RESET, noReset);
caps.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 600);
caps.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.IOS);
caps.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone");
caps.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());
caps.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest");
caps.setCapability("xcodeOrgId", myXcodeOrgId);
caps.setCapability("xcodeSigningId", "iPhone Developer");
caps.setCapability("showXcodeLog", true);
driver = new IOSDriver(new URL("http://" + host + ":" + port + "/wd/hub"), caps);

以下是appium服务器日志：

我正在使用

Appium server version - 1.12.1 
Java client Version - 7.0.0

Answer 1

在Appium 1.12.1中，必须设置platformVersion。要添加的代码：

caps.setCapability（“ platformVersion”，“ 12.2”）;

12.2是iOS的版本。

错误：“空”不能强制为有效的版本号
