hello guys,
i am trying to deploy my application on heroku but when i type gem install something wrong happens as you can see in the image attached in this topic. some of you can help me to find a way to fix this? thanks 
i am using Linux Ubuntu 14
i already installed libpq

If I remember well, you should first install:
- lib-pq-dev
- build-essential
- The Postgres server
i tryied but the same error message persists!
Close, but it should be ‘libpq-dev’. You’ll likely also need ‘psycopg2’
Here’s the order I provision in:
-
build-essential
-
git
-
psycopg2
-
postgresql-9.3
-
libpq-dev
ok. so i just need to run apt-get install and the names enumerateds above, rigth?
