Vagrant up command the response in error “No usable default provider could be found for your system”. Vagrant issues solved.
My environment
OS: Windows 10
Vagrant is version 2.2.6
Virtualbox is version 6.1
I installed the latest Vagrant and VirtualBox versions. I got the following error.
$ vagrant.exe up
No usable default provider could be found for your system.
Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.
The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.
If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
vagrant up --provider=PROVIDER, which should give you a more specific
error message for that particular provider.
Vagrant issues solved the problem
You need to downgrade Virtualbox to version 5.2. Vagrant support PROVIDER here.
The VirtualBox provider is compatible with VirtualBox versions 4.0.x, 4.1.x, 4.2.x, 4.3.x, 5.0.x, 5.1.x, 5.2.x, and 6.0.x.
I decided to downgrade from Virtualbox 6.1 to Virtualbox 5.2
