Failed to install plugin depending on the "nokogiri" gem

[legal90]

Vagrant version

1.9.6

Host operating system

macOS Sierra 10.12.5

Description

That issue is related to #8593 and #8594.
hashicorp/vagrant-installers#104 was supposed to be a fix, but seems like it doesn't help.

$ vagrant plugin install vagrant-parallels

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:

That issue was reproduced on a clean Vagrant installation, with ~/.vagrant.d purged.
Running with NOKOGIRI_USE_SYSTEM_LIBRARIES=true produces the same output.
xcode-select --install is installed, pkg-config executable is available.
Also, libxml/xmlversion.h is available in both of Vagrant sandbox dir and in the system:

$ find /usr -name 'xmlversion.h'
/usr/include/libxml2/libxml/xmlversion.h

$ find /opt/vagrant -name 'xmlversion.h'
/opt/vagrant/embedded/include/libxml2/libxml/xmlversion.h

Expected behavior

Plugin installed

Actual behavior

What actually happened?

Steps to reproduce

vagrant plugin install vagrant-parallels

JFYI: The same plugin version is installing fine under Vagrant 1.9.5 with NOKOGIRI_USE_SYSTEM_LIBRARIES set:

$ NOKOGIRI_USE_SYSTEM_LIBRARIES=true vagrant plugin install vagrant-parallels

Fetching: vagrant-parallels-1.7.5.gem (100%)
Installed the plugin 'vagrant-parallels (1.7.5)'!

Also happening on El Capitan (10.11).

Note however that the NOKOGIRI_USE_SYSTEM_LIBRARIES trick doesn't fully work for me on 1.9.5 - I can install ok, but then I can't actually run vagrant.

Keeping this open until release is out with fix included

[legal90]

@chrisroberts Could you please cut a new version or release a hotfix release of 1.9.6 with hashicorp/vagrant-installers#114 included?

It is really urgent for us since all the plugins depending on nokogiri gem are not compatible with Vagrant 1.9.6 at all 😢

[chrisroberts]

@legal90 I have the fix integrated into the installers repo. Needed to address a couple other things before cutting the next release but will be doing so later today.

[legal90]

@chrisroberts Thank you! 👍

[HarryWeppner]

@chrisroberts do you have an update? We rely on a fix in 1.9.6 but this regression blocks using it :-/

[chrisroberts]

@HarryWeppner Some things needed to be finalized before the next release. It is currently in progress and this issue will be closed once it is available.

[chrisroberts]

Fixed in latest release.
