Question

I use a MacBook Pro and install flutter, but when I type flutter doctor , it doesn't respond (about 10 minutes passed).

flutter doctor

this issue same to me, but I don't install Mamp software.

Answer 1

Without sounding silly, are you connected online? This happens to me when I'm disconnected from the Internet.

Also, what happens when you do this?

> flutter upgrade

Does it still lock up then, or does it actually check the version before eventually continuing and running flutter doctor?

Answer 2

try to run command : flutter maybe you get some error, and fix it. i also get error:

The term 'Unblock-File' is not recognized as the name of a cmdlet, function, sc
ript file, or operable program. Check the spelling of the name, or if a path wa
s included, verify that the path is correct and try again.

Flutter requires PowerShell 5.0 or newer.
See https://flutter.dev/docs/get-started/install/windows for more.
Building flutter tool...
Running pub upgrade...
The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.

Because flutter_tools requires SDK version >=2.2.2 <3.0.0, version solving
  failed.

and i fix it.

If on Windows and flutter doctor is not responding , it means it needs administrative privileges. Just go to search bar , find Command prompt and run it as administrator. That should do.

Answer 4

如果在 Windows 上尝试打开任务管理器并结束/终止所有 dart.exe 进程，则可能是 flutter doctor 正在等待另一个 dart.exe 进程完成该进程，无论出于何种原因都没有完成
