另外，安卓版本是否低于 5.0，2 对低版本支持不好

看看这个https://testerhome.com/topics/2150

感谢，我的手机确是 4.4.2，有时间找个高版本手机试一下

中文的可以

第六步出现了权限问题，按照提示执行如下脚本修复：

···
sudo chmod 777 /usr/local/lib/node_modules
···

感谢。

把我安装过程中的一些错误纪录一下：

第七步：

JamesdeiMac:~ jameslee$ cnpm install -g ios-deploy

我的 Mac 上 xcode 和命令行工具都有， 网上 google 了一下，执行如下命令：
···
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
···

然后继续安装就成功了。

请大神们指点

兄弟这个问题解决了没?

我也遇上同样的问题了, java-client 5.0.4 + appium desktop 1.2.4 , 也是输入不了密码

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Andorid Emulator");
        capabilities.setCapability("automationName", "uiautomator2");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("platformVersion", "4.4.2");
        capabilities.setCapability("appPackage", "com.test.doctor");
        capabilities.setCapability("appActivity", ".user.UserLoginActivity");
        capabilities.setCapability("newCommandTimeout", 0);
//        capabilities.setCapability("unicodeKeyboard", true);
//        capabilities.setCapability("resetKeyboard", true);

        URL url = new URL("http://127.0.0.1:4723/wd/hub");
        driver = new AndroidDriver(url, capabilities);
        driver.manage().timeouts().implicitlyWait(sleepInterval, TimeUnit.SECONDS);

Appium-desktop 异常为:

小弟新手,我使用的代码如下:
driver.findElement(By.xPath("//android.view.View[@content-desc='业务说明']");

这里要注意的是有时候 业务说明 这几个字后面会有空格, 不知道是不是开发人员无意弄得.

推荐个淘宝视频？

安装个 python 的开发工具，类似于 pycharm 之类，然后在里面选择包安装，能安装 http。client 吗？
