“Exec error: exec: “ruby”: executable file not found in %PATH%”

## Vagrant version

2.1.1

## Host operating system

Windows 10

I am having a strange issue where vagrant works fine for a while, and then all of a sudden it completely stops working and any vagrantcommands I run, just give me: "Exec error: exec: "ruby": executable file not found in %PATH%"

It happened yesterday and after a restart didn't fix it, I uninstalled/reinstalled it and it started working again.

Today I've cmoe back to it and again it was working fine, I created a box, went in and did some stuff on it then destroyed it, then created another one, and all was working fine. Then I did a vagrant upon the new box i initialised... I got a lot of warnings, but it got there in the end:

But now any vagrantcommand, inlcuding just vagrantitself, and all I get is:

"Exec error: exec: "ruby": executable file not found in %PATH%"

Nothing has changed on my PC from the time I ran vagrant uptill now.

Can anyone help please?

Thanks.
