macos git: 'credential-wincred' is not a git command. See 'git --help'

解决办法：

git config --unset-all credential.helper

git config --global credential.helper osxkeychain

 

原因：

The problem is that you're trying to use the wincred credential helper, which is only available on Windows, on macOS. You mentioned that you've run git config --global credential.helper wincred, which sets the credential helper to wincred. When Git tries to invoke it, it fails because it's unavailable.

Instead, you should run git config --unset-all credential.helper and run git config --global credential.helper osxkeychain. That will result in you using the macOS Keychain for storing credentials, which will work on macOS.
