Debugging pliigo-cups-agent on ubuntu
When trying to install pliigo cups agent on ubuntu via npm (sudo npm install pliigo-cups-agent -g), you may run into an issue like the following:
cups-config: not found
if an error happens and it looks like this:
/usr/local/bin/pliigo-cups-agent -> /usr/local/lib/node_modules/pliigo-cups-agent/bin/pliigo-cups-agent > email@example.com install /usr/local/lib/node_modules/pliigo-cups-agent/node_modules/printer > node-gyp rebuild /bin/sh: 1: cups-config: not found gyp: Call to 'cups-config --libs' returned exit status 127 while in binding.gyp. while trying to load binding.gyp gyp ERR! configure error gyp ERR! stack Error: `gyp` failed with exit code: 1 gyp ERR! stack at ChildProcess.onCpExit (/usr/share/node-gyp/lib/configure.js:354:16) gyp ERR! stack at emitTwo (events.js:87:13) gyp ERR! stack at ChildProcess.emit (events.js:172:7) gyp ERR! stack at Process.ChildProcess._handle.onexit (internal/child_process.js:200:12) gyp ERR!

If you do, this is most likely a problem with the printer package, npm ERR! not with npm itself. npm ERR! Tell the author that this fails on your system: npm ERR! node-gyp rebuild npm ERR! You can get information on how to open an issue for this project with: npm ERR! npm bugs printer npm ERR! Or if that isn't available, you can get their info via: npm ERR! npm owner ls printer npm ERR! There is likely additional logging output above.
try running the
cups-config command and see what it returns, if it is something like:
npm ERR! Please include the following file with any support request: npm ERR! /home/jon/Development/printer/npm-debug.log npm ERR! code 1 The program 'cups-config' is currently not installed. You can install it by typing: sudo apt install libcups2-dev
Do what it says and run:
sudo apt install libcups2-dev
this will install our cups lib, now running that same command should return the usage documentation for that script. Try to install our npm module again and it should now work!
