运行 run.py 时报错，您知道怎么解决么？谢谢~没怎么用过 python，不太理解

python 的版本是 2.x 还是 3.x?

问题有解决吗？我也遇到同样的问题

#2 楼 @xiaoxuxu 问题解决了么？谢谢~

您好，我也是 appium 切换 webview 后,进入 url 后再次点击链接，进入第二页面的 url 后没有反应，此时使用代码： System.out.println(driver.getCurrentUrl());一直没有响应，知道最后 timeout 了。貌似加载到第二页的 url 后，chromedriver 不能获取 body 的信息，导致这个页面加载失败。有人解决这个类似的问题么？

timeout 之前显示错误信息：

@codeskyblue 谢谢，我的问题解决了，最终用的 chromedriver2.5，解决了问题，配置代码如下：
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("platform", "ANDROID");
caps.setCapability("platformVersion", "5.1.1");
caps.setCapability("deviceName", "A02AECPB2CLTG");
caps.setCapability("browserName", "");
caps.setCapability("app", "");

caps.setCapability("appPackage", "com.tencent.mm");
caps.setCapability("appActivity", ".ui.LauncherUI");
caps.setCapability("fastReset", "false");
caps.setCapability("fullReset", "false");
caps.setCapability("noReset", "true");

ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("androidProcess", "com.tencent.mm:appbrand1");
caps.setCapability(ChromeOptions.CAPABILITY, options);
driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), caps);
实现代码如下：
@Test
public void miniProgramTest() throws Exception {

// println(driver.getPageSource)
driver.findElementByXPath("//[@text='发现']").click();
Thread.sleep(1000);
driver.findElementByXPath("//[@text='小程序']").click();
Thread.sleep(1000);
driver.findElementByXPath("//[contains(@text, 'QQ 阅读')]").click();
Thread.sleep(3000);
driver.findElementByXPath("//[@text='书库']").click();
Set contextNames = driver.getContextHandles();
Thread.sleep(1000);
for (String contextName : contextNames) {
System.out.println(contextName);
}
driver.context("WEBVIEW_com.tencent.mm:tools");
Thread.sleep(1000);
System.out.println("已经进入 WEBVIEW 啦");
//System.out.println(driver.getPageSource());
String s1 = driver.getWindowHandle();

driver.findElementByXPath("//*[contains(@url, '古代')]").click();
driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
Set set1 = driver.getWindowHandles();
//System.out.println(set1);
for(String windows: set1){
if (windows.equalsIgnoreCase(s1)){

}else{
driver.switchTo().window(windows);
}
}
//driver.manage().timeouts().implicitlyWait(60,TimeUnit.SECONDS);
Thread.sleep(2000);
driver.findElementByXPath("//[contains(@url, 'bid=716295')]").click();
String s2 = driver.findElementByXPath("//[contains(@url, 'bid=716295')]").getText();
System.out.println(s2);
Assert.assertTrue(s2.contains("美人榻"));
Thread.sleep(3000);
driver.context("NATIVE_APP");
System.out.println("已经回到 NativeAPP 啦");
driver.findElementById("com.tencent.mm:id/io").click();
//driver.findElement(By.id("com.tencent.mm:id/io")).click();
}
代码运行正常了，有遇到同样的问题，可以尝试一下我的方法。

#17 楼 @601068603 问题解决了么？谢谢~

#19 楼 @luke 请问，切换到 Weview 后不操作 find element 怎么解决呢？谢谢~

#64 楼 @codeskyblue 我觉得我这边现在是切换到了 WebView，但是不能对其元素进行操作，不知道具体问题在哪了，也可能是权限问题，H5 开发的时候，不让对其元素进行操作，这是我的猜测。你那边要是解决了，到时候分享一下哈~

@codeskyblue 你那边的微信小程序，测试是可以通过的么？谢谢~

#61 楼 @codeskyblue chromedriver 我降到了 2.3，2.4，2.5，2.2，2.1，目前提示的错误信息不一样了，代码运行到切换 webview 之后，一直没有响应，最后提示 org.openqa.selenium.NoSuchSessionException: no such session。server 端的提示信息是：我上传一个截图吧。

微信的 WebView 版本可以通过 Chrome 的 ADB plugins 在 Inspect 页面元素的时候看到。

#59 楼 @codeskyblue 您好，我的微信的 Webview 显示的是 53.0.2785.49，然后我手机上的 Chrome 是 55 的，这个有影响么？chromedriver 具体是根据哪个版本来选择合适的？是根据微信 Webview 的么？

#22 楼 @ort886 ChromeDriver 换成什么版本了？

我也遇到一样的问题@codeskyblue，提示：unknown error: Chrome version must be >= 54.0.2840.0\n (Driver info: chromedriver=2.27.440174 。不知道怎么处理。
