Frontend Masters lineman install issue

[Nooshu]

Hello,

I'm just following along on your course on FEM and I have just run into an issue. When doing an npm install from the lineman directory I get this nasty looking error

png@3.0.3 install /Users/name/Development/tutorial-machine/build/js-testing/real-world-testing-video/lineman/node_modules/png
node-gyp rebuild

Looking into the issue it looks like one of the PNG dependencies is broken, but after the issue was raised there's no fix pkrumins/node-png#50.

Is this something you have come across or could verify if it is an issue for you too. I'm on OSX 10.11.6.

Great course by the way!

First, thanks for the kind words about the course.

Second, yes I see this too:

> node-gyp rebuild

Package libpng was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpng.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libpng' found

I don't really have a great answer for you 😦 -- @davemo, thoughts?

I was able to continue with the FEM course by globally installing lineman
