What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version?

{ "name": "", "build": "", "support": "*", "version": 0, "description": "***", "authorization_endpoint": "" "token_endpoint": "", "min_cli_version": null, "min_recommended_cli_version": null, "app_ssh_endpoint": ":2222", "app_ssh_host_key_fingerprint": "", "app_ssh_oauth_client": "ssh-proxy", "doppler_logging_endpoint": "", "api_version": "2.146.0", "osbapi_version": "2.15", "user": "****" } cf version 6.44.0+5de0f0d02.2019-05-01

What version of the buildpack you are using? 1.7.8

If you were attempting to accomplish a task, what was it you were attempting to do? Pushing a CF app using an environment.yml file that specifies the Python version & dependencies.

What did you expect to happen? Miniconda3 should be installed by the default, because miniconda2 was removed in 1.7.7.

What was the actual behavior? The buildpack was trying to install miniconda2. Here's the log: Staging app and tracing logs... Downloading python_buildpack...

Hey guys, I am facing the same issue. Can you please tell me what needs to be written in runtime.txt to make it work?

sushanthmangalore commented 4 years ago

Was able to push the app by creating runtime.txt in the application's base directory and specifying the Python version in it.

SanjivShenoy commented 4 years ago

@sushanthmangalore, it worked! Thanks a lot!
