Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

extconf failed, exit code 1

Gem files will remain installed in /home/mani/rubyrails-tasks/vendor/bundle/ruby/2.3.0/gems/pg-1.0.0 for inspection.
Results logged to /home/mani/rubyrails-tasks/vendor/bundle/ruby/2.3.0/extensions/x86_64-linux/2.3.0/pg-1.0.0/gem_make.out

An error occurred while installing pg (1.0.0), and Bundler cannot continue.
Make sure that gem install pg -v '1.0.0' --source 'https://rubygems.org/' succeeds before bundling.

In Gemfile:
pg

Answer 1

did you add and commit files before pushing?

this looks like a git error on your local box and I don't think it's app service related.
