If you would like to contribute to Dallinger, please follow these alternative install instructions.
Dallinger is written in the language Python. For it to work, you will need to have Python 2.7 installed. You can check what version of Python you have by running:
If you do not have Python 2.7 installed, you can install it from the Python website.
Dallinger uses Postgres to create local databases. On OS X, install Postgres from postgresapp.com. This will require downloading a zip file, unzipping the file and installing the unzipped application.
You will then need to add Postgres to your PATH environmental variable.
If you use the default location for installing applications on OS X
/Applications), you can adjust your path by running the
NB: If you have installed a more recent version of Postgres (e.g., the the upcoming version 9.4), you may need to alter that command slightly to accommodate the more recent version number. To double check which version to include, then run:
Whatever number that returns is the version number that you should place
export command above. If it does not return a number, you
have not installed Postgres correctly in your
or something else is horribly wrong.
Create the Database¶
After installing Postgres, you will need to create a database for your experiments to use. Run the following command from the command line:
psql -c 'create database dallinger;' -U postgres
Install Dallinger from the terminal by running
pip install dallinger
Test that your installation works by running:
If you use Anaconda, installing Dallinger probably failed. The problem is
that you need to install bindings for the
psycopg2 package (it helps
Python play nicely with Postgres) and you must use conda for conda to
know where to look for the links. You do this with:
conda install psycopg2
Then, try the above installation commands. They should work now, meaning you can move on.
Next, you’ll need access keys for AWS, Heroku, etc..
