Hello Karl, In the GAE Python 2.7 runtime, six was part of the 3rd party libraries which was bundled as part of the runtime[1]. With Python 3.7, some of these libraries were not included in the runtime in order to provide a more idiomatic python environment and need to be migrated[2] by specifying these previously bundled libraries into the requirements.txt
