我错了，没看到下面得，你以管理员权限运行一下。或者appium desktop也是管理员权限。这个权限问题

• 提问者 慕运维2948618 #1

  真的可以耶~老师厉害！请问老师是从哪里看出来的？

• 提问者 慕运维2948618 #2

  非常感谢！

• 菜鸟学飞ing #3

  老师，我试了用管理员权限运行，还是报错“selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: The application at 'E:\ Appium\FXJC_Appium_Python\Test_APK\fxjc-app-prod-2018080110-release-signed.apk' does not exist or is not accessible

  我在用了“"automationName":"UiAutomator2",”这个以后，也出现了这个报错，请问是怎么解决的呢？

Answer 3

Mushishi 2018-07-21 11:03:43

你这个是mac下？你这个是权限问题造成得。你安装得时候是不是sudo去安装了。不要sudo。如果sudo那么你就要用sudo去启动appium

  我用的是windows电脑。

提问者 慕运维2948618 2018-07-21 01:31:01

这里报Could not sign with default certificate的错误，我在网上找了很久都没有找到原因，希望老师看看是怎么回事。我使用的sdk是老师提供的，其它软件都是使用最新版本的。
