Bundler how to uninstall conflicting dependency

Question

I'm trying to execute vagrant plugin install vagrant-vbguest on my Mac

ProductName:    Mac OS X
ProductVersion: 10.12.6
BuildVersion:   16G29

but I have an error message after that

Bundler, the underlying system Vagrant uses to install plugins, reported an error. The error is shown below. These errors are usually caused by misconfigured plugin installations or transient network issues. The error from Bundler is:

conflicting dependencies winrm-fs (= 1.0.1) and winrm-fs (= 0.2.3)
Activated winrm-fs-0.2.3 which does not match conflicting dependency (= 1.0.1)

Conflicting dependency chains: winrm-fs (= 0.2.3), 0.2.3 activated

versus: winrm-fs (= 1.0.1)

Gems matching winrm-fs (= 1.0.1): winrm-fs-1.0.1

So the question is how to resolve this issue with Bundler of how to just install my guest plugin in a safe manner? Other details

vboxmanage --version                                                                                   
5.1.26r117224
Vagrant 1.9.7

Answer 1

I found a solution:

Uninstall vagrant completely and install it again. But take care, to backup your shares before.

How to uninstall: https://www.vagrantup.com/docs/installation/uninstallation.html

The problem where some old embedded gems inside /opt/vagrant/embedded/gems/gems directory, which I do not know how to update or to select the default version.

VAGRANT_DISABLE_STRICT_DEPENDENCY_ENFORCEMENT=1 vagrant plugin install vagrant-vbguest resolved the issue. Looks like workaround, but it worked for me and everything seems ok right now.
