Ubuntu 16.04 on VirtualBox VM using Vagrant.
Windows 10 host.
Git Bash terminal.
Connected to vagrant up, vagrant ssh.
I have a fresh VM and have installed ruby and rails. I am trying to install postgresql to use for a Ruby on Rails project, but I get the following error:
vagrant#vagrant-ubuntu-trusty-64:~$ sudo apt-get install postgresql postgresql-contrib

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
postgresql : Depends: postgresql-9.6 but it is not going to be installed
postgresql-contrib : Depends: postgresql-contrib-9.6 but it is not going to be installed

I've tried various things, and nothing seems to let me install postgres
I was facing same problem in my ubuntu 16.04
but i fixed that problem and it's very simple just follow these step and you will be able to install postgresql 10 in your system :
Add this to your sources.list:
sudo vim /etc/apt/sources.list
deb http://ftp.de.debian.org/debian/ wheezy main non-free contrib
deb-src http://ftp.de.debian.org/debian/ wheezy main non-free contrib
after that add these link to your pgdg.list file if it's not there you have to create and add link and save it.
sudo vim /etc/apt/sources.list.d/pgdg.list
deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main
then update your system
sudo apt-get update
sudo apt-get upgrade
and install that unmet dependencies :
apt-get install ssl-cert
that's it. now Install postgresql using these command
sudo apt-get install postgresql-10
#JosMac pointed out that I am running Ubuntu 14.04 instead of 16.04 as I had thought.
I was still running into similar errors, but I just ended up installing the rails-dev-box (https://github.com/rails/rails-dev-box) way which uses yakkety64, and seems to work.
I installed POSTGIS on Ubuntu but it doesn't have a shape file loader. I looked it up online and people say use sudo apt-get install opengeo-postgis-shapeloader or sudo apt-get install opengeo-postgis2-shapeloader . I tried both and ubuntu said can't locate package opengeo-postgis-shapeloader. How can i install it?
thank you
I think you can follow this http://suite.opengeo.org/4.1/installation/ubuntu/install.html
to install the mentioned packages
In Centos 6.4,when configure Emacs,it shows:
configure: error: The required function `tputs' was not found in any library.
The following libraries were tried (in order):
libtinfo, libncurses, libterminfo, libtermcap, libcurses
Please try installing whichever of these libraries is most appropriate
for your system, together with its header files.
For example, a libncurses-dev(el) or similar package.
How to fix it,what's the problem in it.
sudo yum install ncurses-devel
then ./configure again
Try to install libncurses-dev with
bash
apt-get install libncurses-dev
I'm on a Debian Wheezy derived distribution (CrunchBang)
Trying to install Emacs 24.5.1
Had to install libncurses5-dev, then run ./configure
$ sudo apt-get install ncurses-devel
...
E: Unable to locate package ncurses-devel
$ sudo apt-get install libncurses5-dev
When I am trying to install sbt in Ubuntu as it is suggested here:
wget http://apt.typesafe.com/repo-deb-build-0002.deb
sudo dpkg -i repo-deb-build-0002.deb
sudo apt-get update
sudo apt-get install sbt
The last command sudo apt-get install sbt asks if I want to install GJI -- GNU java interpreter.
The following extra packages will be installed:
gcj-4.5-jre gcj-4.5-jre-headless
Suggested packages:
fastjar gcj-4.5-jdk
The following NEW packages will be installed:
gcj-4.5-jre gcj-4.5-jre-headless sbt
I do not want to install it. How can I install an sbt package in Ubuntu without GCJ ?
You can go on the sbt website, download it,extract it somewhere in your home directory and add it in the path.
I have it on ~/apps/sbt/ and i added the following in the end of ~/.bashrc
export PATH=$HOME/apps/sbt/bin:$PATH
I found it the simplest way to achive this because the apt typesafe respository is outdated.
Is it possible to install psycopg2 into a virtualenv when PostgreSQL isn't installed on my development system—MacBook Pro with OS X 10.6?
When I run pip install psycopg2 from within my virtualenv, I received the error shown below.
I'm trying to connect to a legacy database on a server using Django, and I'd prefer not to install PostgreSQL on my development system if possible.
Why not install PostgreSQL?
I received an error when installing PostgreSQL using homebrew. I have Xcode4—and only Xcode4—installed on my MacBook Pro and am thinking it's related to missing gcc 4.0. However, this is a problem for another StackOverflow question.
Update 8:37 AM on April 12, 2011: I'd still like to know if this is possible without installing PostgreSQL on my MacBook Pro. However, I ran brew update and forced a reinstallation of ossp-uuid with brew install --force ossp-uuid and now brew install postgresql works. With PostgreSQL successfully installed, I was able to pip install psycopg2 from within my virtualenv.

Preliminary Research
Below are the articles I read as preliminary research:
Installing psycopg2 to use Django with PostgreSQL on OS X
Installing psycopg2 on OS X
Using psycopg2 with virtualenv on Ubuntu JauntyLucid
Postgres, psycopg2, virtualenv install hints
apt-get install libpq-dev
helped me on debian squeeze
From comments:
apt-get install python-dev-is-python3
psycopg depends on pg_config command, and if you don't have it, you can't install psycopg.
If system installation is a problem to you, why don't you try compiling PostgreSQL and including generated bin files in your $PATH? Like:
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
pip install psycopg2
brew install postgresql
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip3 install psycopg2
apt-get install libpq-dev
helped me in debian squeeze too . After that do pip install psycopg2. I faced problem of pg_config not found problem when i was setting up my environment on heroku , now its working fine .
You need to install the python-dev package in order to make use of python extensions such as psycopg2. I don't know how to install packages in mac but I run the following commands to install a python package on my Ubuntu machine.
sudo apt-get install python-dev
Or
sudo apt-get install python3-dev
if you are using Python3.x.
Once the installation is finished run the following command within your virtual environment.
pip install psycopg2
You don't need the complete PostgreSQL installed: you only need the client side libraries.
I solved it in MAC OSX using :
$ wget https://ftp.postgresql.org/pub/source/v9.5.3/postgresql-9.5.3.tar.bz2
$ tar xfv postgresql-9.5.3.tar.bz2
$ cd postgresql-9.5.3
$ ./configure
$ make
$ cd src/bin/pg_config
$ export PATH=`pwd`:"$PATH"
$ pip install psycopg2
Use pip install psycopg2-binary, it worked for me when pip install psycopg2 wasn't working.
Using the method you described in your April 12th update, I was able to install PostgreSQL(+1). Note that I originally was running Python 2.7.1 (32bit) and homebrew threw several errors and warnings regarding using a 32bit version of Python. I have since switched the 64/32 bit version of 2.7.1 and it works like a champ.
Regarding the pyscopg2, I was able to install it into my virtual environment from source by editing setup.cfg. I set pg_config to correct path inside homebrew's Cellar (pg_config=/usr/local/Cellar/postgresql/9.0.4/bin/pg_config). After saving the changes, I ran python setup.py install with zero issues. It's worth noting that I did not set the Mac's default python setting to 32 bit. I used the new 64 bit from start to finish.
After looking over some of the documentation, I think if I added homebrew's postgresql path to the system path I could have used pip to install it.

Update 6-8-2011:
While porting a project written on OS X to Windows 7, I found out that I had to install PostgreSQL on Windows as well. This ended up creating another user on my start up screen and other things that I just didn't like. While doing some digging I found Windows drivers for PostgreSQL here. I have since uninstalled the full PostgreSQL and installed the ODBC drivers which, thus far, work great.
To address the original question, after doing a bit more digging I think I found the equivalent ODBC for OS X here. I have not had a chance to try them out, but the concept works very well on Windows 7. I will update this when I get a chance to try them out. Until then, I hope this helps.
All from the above doesn't work for me (OS Catalina 10.15.1)
There was a conflict with classical postgres and homebrew version.
Please delete homebrew version by command
$ brew uninstall postgresql
and then install it from the official website:
$ sudo mkdir -p /etc/paths.d && echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp
It is actual for a simple psycopg2 install or django-heroku package.
if you have recently updated python or changed default python (let's say from 3.6 to 3.8). The following code
sudo apt-get install python-dev OR sudo apt-get install python3-dev
will be installing/working for the previous python version.
so if you want this command to work for the recently updated/changed python version try mentioning that specific version like python3.8 in command like
sudo apt-get install python3.8-dev
try above with following
pip install wheel
export PATH=/path/to/compiled/postgresql/bin:"$PATH"
sudo apt-get install libpq-dev
sudo apt-get install python3.x-dev **Change x with your version, eg python3.8**
pip install psycopg2-binary
pip install psycopg2
As I never needed to install postgresql database on this server I installed the following libraries on Ubuntu 14_04 version before running pip install psycopg2 on the same server
apt-get install libpq-dev python-dev
and then executed pip install psycopg2 within virtual env.

I know you are asking for development environment but if you are deploying on server say, Heroku.
Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.
Try to specify the version and it'll works, do it inside the venv
pip install psycopg2-binary==2.8.6
based on my experience, apt install libpq-dev then try to install psycopg2 inside venv will fix many issues, however for more information you can refer to this link:
