I don't think there is such a thing as an pub environment that needs to get ready.

Could you try to open https://pub.flutter-io.cn/api/packages in the browser and check if you get JSON response back (several pages long)?

@SunLongbri

Yes , I can get the Json from browser,and I get the Json is :
next_url | "https://pub.flutter-io.cn/api/packages?page=2"

I can get lots of pages:I think my computer's network is good.

Thought ,I resolved this problems ,but when I input the 'flutter doctor ',another problem encounter.

heaven@Heaven-Code-Master:~/Development/flutter$ flutter doctor

When I input the order 'sudo apt-get install lib32stdc++6'
terminal encounter------>

The following packages have unmet dependencies:
 lib32stdc++6 : Depends: gcc-7-base (= 7.2.0-8ubuntu3.2) but 7.3.0-27ubuntu1~18.04 is to be installed

My Computer System :Ubuntu 18.04 64 ,I think I can't install lib32stdc++6 ,because it's 32 .
I think is right?

Maybe you can download Flutter sdk again.

git clone -b dev https://github.com/flutter/flutter.git
