nicknezis opened a new issue #3674:
URL: https://github.com/apache/incubator-heron/issues/3674
**Describe the bug**
When building in Centos 7 Docker image, the build fails due to `uvloop`
Python library depending on Python 3.7 which is newer than the Centos 7
provided Python 3.6.8.
**To Reproduce**
Steps to reproduce the behavior:
When building using `./docker/scripts/build-artifacts.sh centos7 0.20 /tmp/`
the build fails with the following output message.
```

```
**Expected behavior**
The build should produce artifacts without error. Also the
`bazel_configure.py` version check file should properly match the dependency if
we actually need Python 3.7 going forward.
**Operating System**
- OS: Centos 7
- Version master branch
