It suddenly started getting the following error:
npm ERR! Package pangocairo was not found in the pkg-config search path.
npm ERR! Perhaps you should add the directory containing `pangocairo.pc'
npm ERR! to the PKG_CONFIG_PATH environment variable
npm ERR! No package 'pangocairo' found
npm ERR! gyp: Call to 'pkg-config pangocairo --cflags-only-I | sed s/-I//g' returned exit status 0 while in binding.gyp. while trying to load binding.gyp
Trying some advice from
