SnoVault JSON-LD Database Framework

System Installation (OSX Big Sur(testing), Catlina(10.15.x), Mojave(10.14.6))

We will try to keep this updated as OSX, Xcode, and brew update. However the steps below are examples and not guaranteed to work for your specific system. See the dependency's website for detailed instructions or let us know of any changes with a pull request.

1. Command line tools

   xcode-select --install

2. brew: https://brew.sh/ . Make sure git is installed

3. Python 3.8.5

4. Postgres@11 (Postgres@9.3 also works)

   brew install postgresql@11
   # May need to add postgres to PATH in your shell profile, e.g. ~/.bash_profile, ~/.zshrc
   # echo 'export PATH="/usr/local/opt/postgresql@11/bin:$PATH"' >> YOUR_SHELL_PROFILE

5. Node 10.x.x

   brew install node@12

   You may need to link node/npm with brew link node@12 then add it to your PATH

6. Ruby - Non system version to install compass while avoiding permission errors

   brew install ruby
   # May need to add ruby to your bash_profile/zshrc and restart terminal

7. Compass

   gem install compass
   # Test the install
   compass -v
   # If the command is not found then find your ruby bin directory
   ls /usr/local/lib/ruby/gem/
   # If you have two versions use the active one
   ruby -v
   # Using the correct ruby version bin diretory, make a sym link
   ln -s /usr/local/lib/ruby/gems/2.6.0/bin/compass /usr/local/opt/ruby/bin/compass

8. Java 11

   brew install openjdk@11
   # Add to your PATH in terminal profile, i.e. ~/.bash_profile or ~/.zshrc
   export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

9. Elasticsearch 5.x

   # Download tar: https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.0.tar.gz
   
   # Decompress
   tar -xvf ~/Downloads/elasticsearch-5.6.0.tar.gz -C /usr/local/opt/
   
   # Add to PATH in your terminal profile, i.e. ~/.bash_profile or ~/.zshrc
   export PATH="/usr/local/opt/elasticsearch-5.6.0/bin:$PATH"
   
   # Restart terminal and check versions
   elasticsearch -V

10. Brew dependencies

    brew install libmagic nginx graphviz redis

11. Chrome driver for Testing

    Chromedriver is needed in your PATH. If working in a python virtual environment, then the chromedriver can be added to your-venv-dir/bin directory.

    You also need to install Chrome (if not already installed). In addition, allow chromedriver (System Preferences->Security & Privacy) to run to run bdd tests

Application Installation

1. Create a virtual env in your work directory. Here we use python3 venv module. Use venv, like conda, if you please

   cd your-work-dir
   python3 -m venv snovault-venv
   source snovault-venv/bin/activate
   pip install -U pip==21.0.1

2. Clone the repo and install requirements

   cd snovault
   pip install -e '.[dev]'

   If psycopg2 fails to compile, you may need to set LDFLAGS to the output of pg_config --ldflags before pip installation.

   LDFLAGS=$(pg_config --ldflags) pip install -e '.[dev]'

   If you have errors at runtime that look like this:

   ImportError: dlopen(/Users/foo/venv/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so, 2): Symbol not found: _PQencryptPasswordConn
   Referenced from: /Users/foo/venv/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so
   Expected in: /usr/lib/libpq.5.dylib
   in /Users/foo/venv/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so
   

   you may need to add the brew-installed Postgres headers, usually -L/usr/local/opt/postgresql@11/lib, to the LDFLAGS in addition to the ones given by pg_config --ldflags.

3. Build Application

   # Make sure you are in the snovault-venv
   make clean && buildout

4. Run Application

   # Make sure you are in the snovault-venv
   dev-servers development.ini --app-name app --clear --init --load
   # In a separate terminal, make sure you are in the snovault-venv
   pserve development.ini

5. Browse to the interface at http://localhost:6543

6. Run Tests

   • no argument runs non bdd tests

   # Make sure you are in the snovault-venv
   ./circle-tests.sh bdd
   ./circle-tests.sh npm
   ./circle-tests.sh
