Trying to build the image using the website repo Dockerfile with the output printed below.
The issue is due to conflicting python versions.

Instructions on https://github.com/brianc/node-pg-native/issues/9 did not fix the issue nor installing the libpq-dev package

Step 15/23 : RUN npm install
---> Running in 1bf3b3b53ba0

> libpq@1.8.8 install /home/bookbrainz/bookbrainz-site/node_modules/libpq
