Error occured when installing postgres gem on rail on windows

Question

I'm learning to use ruby on rails on windows 8.1. I got stuck when I had to install pg(postgres) gem. To be specific, this is the error:

Error: Error installing pg:

   Error: failed to build gem natve extension
   C:/Rails Installer/Ruby2.1.0/bin/ruby.exe extconf.rb
  checking for pg_config... no
No pg_confg... trying anyway. If build fails, please try again with --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
can't find the 'libpq-fe.h header
*** extconf.rb failed ***
could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details.

I'm stuck, any suggestion will help. Thanks

I tried that but I'm still experiencing the same problem... Help please — Sodiq Babalola, Apr 09 '15 at 11:36

Try to identify where the pg_config is located using the Windows command-line tool (source: https://superuser.com/questions/49104/how-do-i-find-the-location-of-an-executable-in-windows):

where pg_config

Copy the path returned and use it

bundle config build.pg --with-pg-config=/path/found/for/pg_config

(based on ERROR: Failed to build gem native extension on Mavericks)

I tried to locate pg_config, but the result is: could not find files for the given pattern, so I think i have to reinstall Postgres...is that a good idea? – Sodiq Babalola Apr 08 '15 at 16:18
Yea, try reinstalling it – MrYoshiji Apr 08 '15 at 16:19
Hi, after the reinstallation, nothing has changed, what do you suggest I do now? – Sodiq Babalola Apr 08 '15 at 17:55
