 Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Library/Frameworks/Python.framework/Versions/3.8/bin/python3-config
  /Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8-config

Warning: Git could not be found in your PATH.
Homebrew uses Git for several internal functions, and some formulae use Git
checkouts instead of stable tarballs. You may want to install Git:
  brew install git

Warning: No developer tools installed.
Install the Command Line Tools:
  xcode-select --install


Warning: Your Xcode does not support macOS 11.
It is either outdated or was modified.
Please update your Xcode or delete it if no updates are available.
Xcode can be updated from the App Store.

Homebrew hasn't supported Bintray for a long time. Your Homebrew is very outdated. First fix your install by doing xcode-select --install and after that is done you should run brew update-reset to reset brew to the latest version.

Thank you very much, your method works.
