I am following the official tutorial of google app engine "Getting Started with Flask on App Engine Standard Environment". The problem is that I cannot run the code successfully on local server. I typed:
dev_appserver.py app.yaml
in the command line and hit enter. Nothing happened and a new line was created. I was running the command in a virtual environment from the root directory where the app.yaml file is located. I have already added "[PATH_TO_CLOUD_SDK]/google-cloud-sdk/bin/dev_appserver.py]" to the PATH environment variable.
Does anyone know what is going on?
