Build does not complete due to issue with Py-YAML #2128

Closed mdhedley closed 5 years ago

It appears that the build script is being impacted for the pip change documented in this issue: https://github.com/pypa/pip/issues/5247

PyYAML no longer installs as a result of this change in pip 10, and as a result all builds are failing, and all pull requests fail to build.

You can reproduce this error by running build.sh as is. It appears that the default pyyaml package installed by conda is now 5.15 while the google-cloud-dataflow package requires 4.0 > pyyaml < 3.12. Since conda installed pyyaml pip cannot upgrade/downgrade it and as a result the issue errors out.
