# Installing Dallinger with Anaconda¶

If you are interested in Dallinger and use Anaconda, you’ll need to adapt the standard instructions slightly.

## Install psycopg2¶

In order to get the correct bindings, you need to install psycopg2 before you use requirements.txt; otherwise, everything will fail and you will be endlessly frustrated.

conda install psycopg2


## Install Dallinger¶

You’ll follow all of the Dallinger development installation instructions, with the exception of the virtual environment step. Then return here.

## Confirm Dallinger works¶

Now, we need to make sure that Dallinger and Anaconda play nice with one another. At this point, we’d check to make sure that Dallinger is properly installed by typing

dallinger --version


into the command line. For those of us with Anaconda, we’ll get a long error message. Don’t panic! Add the following to your .bash_profile:

export DYLD_FALLBACK_LIBRARY_PATH=$HOME/anaconda/lib/:$DYLD_FALLBACK_LIBRARY_PATH


If you installed anaconda using Python 3, you will need to change anaconda in that path to anaconda3.

After you source your .bash_profile, you can check your Dallinger version (using the same command that we used earlier), which should return the Dallinger version that you’ve installed.
