Gitbook PDF task fails: path undefined

[fusion809]

Hi,

I cloned this repo installed gitbook-cli via running sudo npm install -g gitbook-cli and ran make from the top-level directory of this repository and I received the error message:

gitbook pdf
(node:17051) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

is relevant my operating system is 64-bit Arch Linux, my version of NPM is 3.8.8 and Node.js is 6.0.0.

Thanks for your time, Brenton

Hi,

I am afraid I did not commit (in all senses of the world) the Gitbookification, so I am a little at a loss as to why this is happening. I am going to dive into this at some point, but if any of you have an idea of what this is, please feel free to hit it!

Hi, in my case it was that with earlier versions the commandline simply would work with gitbook pdf. With later versions that changed - so I had to adjust my shellscript:

gitbook pdf./ ./../../books/${BOOK}.pdf

so it contains a source directory, and an output file. I guess its primarily the error message whats so confusing and not pinpointing the original error.

I had the same problem. A simple gitbook update was the proper remedy.
