Unable to install on Windows

[kichik]

I have tried install the latest version on Windows 10 with Vagrant 1.8.5 and kept getting an error. Manually trying to install the gem shows the ruby_dep dependency requires Ruby 2.2.5 and above, but Vagrant comes bundled with Ruby 2.2.3. I have tried installing every version of vagrant-unison2 between 1.0.0 and 1.2.4 with no success.

ruby_dep 1.4.0 came out 2 days ago, so it might be related.

The full error message:

C:\>vagrant plugin install vagrant-unison2

I was able to work around the issue by manually installing ruby_dep first with:

vagrant plugin install ruby_dep --plugin-version 1.3.1
vagrant plugin install vagrant-unison2

I'm also having this problem on OSX and can confirm that the same fix works.

Are you running Ruby < 2.2.5 when you get this error? (Looks like the default OSX ruby on El Capitan is 2.0.0)

[JCook21]

I'm using RVM and the output of ruby -v is 2.3.1. Maybe the plugin install is defaulting to the system Ruby - let me check to make sure the Ruby versions are correct.

[JCook21]

That was the problem - rvm was using 2.2.0. After installing 2.3.1 and setting it as the default all is good, thanks!

[dcosson]

👍 I'm going to close this, but lmk if the windows version is a different bug.

I am unaware of an easy way to upgrade the bundled version of Ruby for Vagrant. Maybe vagrant-unison2 can directly require ruby_dep with a version supported by Vagrant 1.8.5 on Windows?

[JCook21]

@kichik the problem disappeared for me when I upgraded the version of Ruby my shell uses, not the bundled Vagrant one. Maybe that would help? I was using Ruby 2.2.0 installed with RVM. As soon as I installed 2.3.1 and set it as the default Ruby the problem went away. I'm on OSX though so not sure how this would work on Windows.

@dcosson also getting this on OS X, using rbenv w/ ruby 2.2.4 vagrant 1.8.5

[dcosson]

I'm seeing this on OSX too once I updated to vagrant 1.8.5.

It looks like this PR is related https://github.com/mitchellh/vagrant/pull/7684 so hopefully vagrant 1.8.6 will fix this issue.

Until then a workaround is using an older vagrant or a newer ruby version, or installing vagrant unison from source by cloning this repo, running bundle install && bundle exec rake build and then vagrant plugin install pkg/vagrant-unison2-2.0.0.gem
