Notes to resolve pg gem issue

gistfile1.txt

Error:
An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

Decision:
gem install pg -v '0.17.1' -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

Decision 2(better):
This problem can happen due to lack of dependencies. To fix it u can try smth like for rvm:
rvm requirements 
Or if u are not use RVM then u can manually setup requirements which can looks like:
 build-essential openssl libreadline6
 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev 
 libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev 
 autoconf libc6-dev ncurses-dev automake libtool bison subversion

BUT: the list of requiremtns can be wrong. So please do more research for your case if `rvm requirements` is not you approach.

Note that u should change 0.17.1 and 9.3 to ur real versions.

UPD: Note that the real problem is that ruby requirements are not met.
