How do I deploy Django app to app engine

[baturay Alhaj Ahmad]

Hello all,

I am having with my app.yaml file when trying to deploy a django app to app engine using gcloud app deploy command.

I am able to deploy the app if I declare python version as 27 but if I declare the verion as 37 I always get the below error

Updating service [default]...failed.

my app.yaml looks like this 

runtime: python37

instance_class: F2

beta_settings:

    cloud_sql_instances: neverland:europe-west3:neverlandsql2

handlers:

- url: /static

  static_dir: static/

- url: /.*

  secure: always

  redirect_http_response_code: 301

  script: auto

env_variables:

  # vars

Any idea why this is happening ??

thanks.

Hello Baturay, 

What is the value of the CLOUDSDK_PYTHON variable at the moment of attempted deployment? Support for version 3.7 is experimental, at present. 

This error is related to the Python version used by the SDK: currently gcloud requires Python version 2.7.x and there is experimental support for 3.4 and up. You can check this by running the gcloud topic startup command on the CLI. Experimental support is what it says, so in this case you cannot deploy your app with CLOUDSDK_PYTHON set to python37. Things should progress towards full support; meanwhile, we should exercise patience. 

This situation should not prevent you from using whatever Python version you need for your project, and your app itself.
