# 答案1
**得分**: 1

以下是已翻译的内容:

**1-** 你可以在电脑上通过命令提示符运行Flutter Doctor。
   你可以通过以下方式打开命令提示符:
   点击Windows开始按钮。
   输入"command prompt"并按回车键。

   一旦我们打开了命令提示符,你可以输入以下内容并按回车键:

    flutter doctor -v

**2-** 然后,如果你使用的是Android Studio,请尝试重新启动你的IDE,并清除缓存。
   在Android Studio中,你可以通过以下方式清除项目结构相关的信息:

    File > Invalidate Cache clears project structure related information (only) cached by Android studio.

**3-** 如果这没有奏效,请尝试更改包的版本号。

**4-** 最后,删除该包并用另一个包替换,可以从[github.com][1]或[pub.dev][2]获取另一个包。

   [2]: https://pub.dev/

这就是我的解决方案,希望能够解决问题,祝一切顺利!

There are many solutions here are they:

**1-** You can run Flutter Doctor on a PC by using the command prompt. 
you can open the command prompt by: 
Clicking on the Windows Start button. 
Typing in command prompt and 
pressing Enter.

Once we have the command prompt open, you can type the following and hit enter:

    flutter doctor -v

**2-** Then try to restart your IDE if you had android studio go and delete cache from the 

    File &gt; Invalidate Cache clears project structure related information (only) cached by Android studio.

**3-** if it didn&#39;t work try changing the package version number

**4-** lastly delete the package and replace it with another one either from [github.com][1] or [pub.dev][2]

  [2]: https://pub.dev/


Thats my solution I hope it works, all the best!
