Unable to install pg gem on ubuntu - Can’t find the 'libpq-fe.h header

这是尝试执行bundle install时的错误

Building native extensions.  This could take a while...

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
