Recently, I used Conan center to download the third-party library. It was good before, but suddenly it didn’t work

update the URL corresponding to Conan center. The latest is:

conan-center: https://center.conan.io [Verify SSL:True]

Previously, the default value was

https://conan.bintray.com/

Update Conan version

pip install --upgrade conan

the first run will automatically delete things related to the certificate. If not, go to the relevant directory and delete them manually. So far, the problem has been solved</ h6>

conan --version
