A virtual environment is a tool that helps to keep dependencies required by different projects separate. In this setup, we will be creating a virtual environment from which to run the Flow Production Tracking Event Daemon Trigger (shotgunEvents).

To create a virtual environment, start by opening a Terminal and ensuring you are in the directory in which you downloaded the repos. In this example, the directory is Users/newuser/shotgridDemo.

cd Users/newuser/shotgridDemo

To install a virtual environment, use the following command:

pip install virtualenv

Create a virtual environment directory.

mkdir VirtualEnvs

Change directories to the virtual environment directory.

cd VirtualEnvs

From within the VirtualEnvs directory, create a sg_events directory.

mkdir sg_events

Setup a virtual environment.

python -m venv sg_events

If you get an error “zsh: command not found: python”, add python to zsh by running the following in terminal:

echo "alias python=/usr/bin/python3" >> ~/.zshrc

This will configure your zsh profile to run /usr/bin/python3 when python is run. If you are still facing issues, ensure that python=$ where the $ sign should equal the path python is installed on. Restart your terminal. When you open it again, your python command should work successfully. Navigate back to the VirtualEnvs directory and run the python command again.

Once run, the python command will create several new directories within the sg_events folder. You should have something like the image below.

Next, from within the VirtualEnvs directory, activate the virtual environment.

. sg_events/bin/activate

The virtual environment should now be active, indicated by parentheses.
