firebase nodejs: /usr/lib/x86_64-linux-gnu/libgs.so: No such file or directory

Hi,

I'm getting this error when I try to deploy to firebase nodejs - any input on what I'm missing is much appreciated:

Deployment error.

I was trying to override --GS4JS_HOME but then it fails during the npm install ghostscript-js.

Hi @arthabus,
I don't know firebase, but I think that the problem is that in your production environment you don't have the ghostscript installed. The installation process try to link the ghostscript library using the default path /usr/lib/x86_64-linux-gnu/libgs.so.
You can use two environment variables:

• GS4JS_HOME is path the where ghostscript library is installed. Usually in /usr/lib/x86_64-linux-gnu/
• GS4JS_LIB is the name of the ghostscript file library. Usually libgs.so
  In your deployment process the best thing is to set the two environment variables if necessary and then start the installation of modules for your application:

export GS4JS_HOME=/usr/lib/x86_64-linux-gnu/ && \
export GS4JS_LIB=libgs.so && \
npm install

Obviously you need to have ghostscript installed on your production environment.

@NickNaso thanks. Yes, I guess the problem is that it's not installed.

And sorry for the dumb question but how do I install ghostscript to node?

Till today I was only using node with npm - this is how I installed any needed modules so far. Any articles or how to google it would be very helpful ("install new modules to node" or similar returns "use npm"). I know I'm missing something fundamental here...

Hi @arthabus,
sorry for the late in response to you. To allow you to easily use ghostscript4js on serverless environment I need to make all the tasks that I discussed here: #55 (comment)
Maybe a simple workaround could be to build ghostscript library and put it on ta folder inside of your project then you can set the environment variables GS4JS_HOME e GS4JS_LIB to point to that folder and file library. At that point all should work well. I think that you need to build the library for Linux.
