尝试在 https://pub.dartlang.org 查找 package cupertino_icons 时出现套接字错误

Question

Whenever i try to create a new project in flutter through git bash or command prompt, i keep on getting this error Got socket error trying to find package cupertino_icons at https://pub.dartlang.org. I have upgraded the flutter sdk to the latest version but still the same problem. Please how do i solve this issue. Thanks

Answer 1

I would advice anyone that might still be having this problem to TRY the following simply steps:

1. open environment variable settings
2. create a new variable with the name: PUB_HOSTED_URL and its value: https://pub.flutter-io.cn
3. create a new variable with the name: FLUTTER_STORAGE_BASE_URL and its value: https://storage.flutter-io.cn

This did it for me. After spending weeks tryna figure it out. Would love to save someone the headache i went through.

Answer 2

I have both issues. With:

1. Corporate firewall. Look here for solution
2. Env variables (Win system env vars). Create two of them:
   • name : PUB_HOSTED_URL; value : https://pub.flutter-io.cn
   • name : FLUTTER_STORAGE_BASE_URL; value : https://storage.flutter-io.cn

Answer 3

自己花了2个小时，除了之前的设置，检查你的杀毒软件，我的自动阻止了flutter，所以完全禁用你的杀毒软件然后再次尝试运行，希望这对某人有所帮助。

Answer 4

On Linux, this worked for me and for many other people... It should work for you too.

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

On windows, you should create an environment variable with:

name: PUB_HOSTED_URL
 
value: https://pub.flutter-io.cn

name: FLUTTER_STORAGE_BASE_URL

value: https://storage.flutter-io.cn

Answer 5

I have found that resetting your wifi router works. It's happened to me twice and it worked after I reset my router.

Answer 6

Using a VPN for access to the inte.net did the trick for me.
