Re: Running flask on AWS SAM
export SERVER_NAME="0.0.0.0:3000 sam local start-api" just exports everything and does not execute. I tried export SERVER_NAME="0.0.0.0:3000" sam local start-api comes back with the same error. Shekar -- https://mail.python.org/mailman/listinfo/python-list
Running flask server under virtualenv
Hello, I am using Python 3.62 on a mac. I am working under a virtualenv. I generated server code via http://editor.swagger.io (Swagger UI) Steps to reproduce python3 -m venv flaskglobal source flaskglobal/bin/activate cp binary to flaskglobal and unzip contents cd python-flask-server pip install -r requirements.txt python -m swagger_server I am getting the following error when running flask server. I have a model called binary. I am guessing a path issue. In the model, the code is: from __future__ import absolute_import from swagger_server.models.binary import Binary ## <-- Error from .base_model_ import Model from datetime import date, datetime from typing import List, Dict from ..util import deserialize_model . Error: from .binary import Binary File "/Users/ctippur/cyclops/cyclopscloud/flaskapi/cyclopsflaskglobal/python-flask-server/swagger_server/models/binary.py", line 4, in from swagger_server.models.binary import Binary Here is the tree for swagger server that got generated via swagger UI (http://editor.swagger.io) ├── Dockerfile ├── README.md ├── git_push.sh ├── requirements.txt ├── setup.py ├── swagger_server │ ├── init.py │ ├── main.py │ ├── pycache │ │ ├── init.cpython-36.pyc │ │ ├── main.cpython-36.pyc │ │ ├── encoder.cpython-36.pyc │ │ └── util.cpython-36.pyc │ ├── controllers │ │ ├── init.py │ │ └── default_controller.py │ ├── encoder.py │ ├── models │ │ ├── init.py │ │ ├── pycache │ │ │ ├── init.cpython-36.pyc │ │ │ ├── base_model_.cpython-36.pyc │ │ │ ├── binary.cpython-36.pyc │ │ │ └── body.cpython-36.pyc │ │ ├── base_model_.py │ │ ├── binary.py Swagger declaration file content or ur Could this be a pythonpath issue? -- https://mail.python.org/mailman/listinfo/python-list
Re: Running flask server under virtualenv
My bad. I was playing around with it. It should be: from swagger_server.models.binary import Binary -- https://mail.python.org/mailman/listinfo/python-list
