搜索了一下站内，也有同学遇到过这个问题：
http://testerhome.com/topics/715
但其解决办法，删除 AppiumBootstrap.jar，不过后面跑测试用例又报错了：
info: [debug] Error: Could not find AppiumBootstrap.jar; please run 'grunt buildAndroidBootstrap'
at null. (D:\software\python\Appium\node_modules\appium\lib\devices\android\android.js:358:10)
at Object.oncomplete (fs.js:107:15)
info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Could not find AppiumBootstrap.jar; please run 'grunt buildAndroidBootstrap')","origValue":"Could not find AppiumBootstrap.jar; please run 'grunt buildAndroidBootstrap'"},"sessionId":null}
求各位大神指点。
代码块不要用引用格式……有代码块的格式的，请看页面底部的 markdown 说明。
你删了还得再编译个 jar 文件给它啊。
话说你那个帖子是 1.0.0 的了，现在不一定适用了。
#1 楼 @chenhengjie123 谢谢，现在更新到用 AppiumForWindows-1.3.7.1 的版本，报错还是一模一样。排查了一下，appium 没什么问题，应该是我 sdk 下的 UiAutomator 有问题，我先看看，不行再来请教。
请问解决了吗？我也遇到了同样的问题，谢谢！
