After we made changes to docker-compose.yml file to add volume I started getting problems. It could be a parsing issue of the directory…

When I try:

> docker-compose up

I get this error:

> validating C:\Users\yousi\Documents\Docker Tutorials for Beginners\Section 6- Compose\section6-vidly\vidly\docker-compose.yml: services.api.environment.volumes must be a string, number, boolean or null

I don’t know if this is relevant, but you might try taking the spaces out of the folder names.
