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 vagrant commands 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 up on the new box i initialised... I got a lot of warnings, but it got there in the end:

But now any vagrant command, inlcuding just vagrant itself, 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 up till now.

Can anyone help please?

Thanks.

I've just done another reinstall, and found that in /HashiCopr/Vagrant/embedded/mingw63/bin there is a "ruby.exe" file, which was missing before. When I checked when I was getting the error, there was only the "rubyw.exe", so something is deleting that ruby.exe file somehow, seemingly at random.

[cwarwicker]

And again:

PS M:\Web\moodle> vagrant box add centos/7
==> box: Box file was not detected as metadata. Adding it directly...
A name is required when adding a box file directly. Please pass
the `--name` parameter to `vagrant box add`. See
`vagrant box add -h` for more help.
PS M:\Web\moodle> vagrant add box centos/7
Exec error: exec: "ruby": executable file not found in %PATH%
PS M:\Web\moodle>

Check before running the first command and ruby.exe was there, checked after getting the error and it's gone.

Hi there,

This is most likely caused by antivirus software running on your system that is quarantining the ruby executable.

[cwarwicker]

Odd, I checked the list of files it's removed and though it had removed some from hashicorp (ssh.exe, rsync.exe and curl.exe) ruby.exe wasn't in there.

I've just installed ruby manaully from the rubyinstaller and added that to my path, which seems to have fixed it for now.

[Kishoresan]

where did you download ruby installer from?

[strudi]

I have had the same problem and when i restored curl.exe file, it started working again

[chrisroberts]

Closing this as it's due to third party software. Cheers!
