How to install ruby-augeas gem? (macOS Mojave)

Question

I spent most of the day yesterday searching for a clear answer for installing ruby-augeas. I can't find a good solution.

How do I install it?

The error while installing:

gem install ruby-augeas
    Building native extensions. This could take a while...
    ERROR:  Error installing ruby-augeas:
        ERROR: Failed to build gem native extension.

    Gem files will remain installed in /Users/vmware/.rvm/gems/ruby-2.4.4/gems/ruby-augeas-0.5.0 for inspection.

I have also installed brew install augeas pkg-config, but it shows same error.

Do you have `libxml2` installed? For example with `brew install libxml2`? — spickermann, Sep 23 '19 at 12:56

Finally, I have solved this issue.

export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig"

This is all you need. The configure script will run pkg-config to find out what to add to LDFLAGS and CPPFLAGS.
