Google-cloud-python: BigQuery: Valid `google-resumable-media` versions conflict with Cloud Storage

[daniel-humu]

It looks like #9572 introduced a dependency conflict for google-resumable-media between the latest google-cloud-storage and google-cloud-bigquery releases.

Environment details

1. Python 3.7

Steps to reproduce

1. pip install google-cloud-storage (latest release is 1.23.0)
   2.pip install google-cloud-bigquery (latest release is 1.21.0)
2. Try to import both libraries in the same python

Issue

Today, google-cloud-storage 1.23.0 was released. It depends on google-resumable-media >= 0.5.0, < 0.6dev. The current google-cloud-bigquery version, depends on google-resumable-media >= 0.3.1, != 0.4.0, < 0.5.0dev

Therefore, the setup.py files for these two libraries will 2nd level dependency conflict when you attempt to pip install.

This can be fixed by releasing a new google-cloud-bigquery version. (to pick up the changes in #9572)

@tswast Are we at a good spot to release a new version of google-cloud-bigquery?

@daniel-humu Thanks for the report!

Hello Daniel! Thank you for providing the solution. I have a small question related to this error. What does it mean "google-resumable-media >= 0.3.1, != 0.4.0, < 0.5.0dev"? Why does this description mention 3 different versions?

[daniel-humu]

@icymai Are you asking how version specifiers work? The dependency google-resumable-media >= 0.3.1, != 0.4.0, < 0.5.0dev means that the package depended on versions greater than or equal to 0.3.1, less than 0.5.0dev and excluding the 0.4.0 version.

You can read more documentation on version specification on the Python website.

Cool! I haven't read this doc before. Thank you :D
