Janek Szynal commented on AIRFLOW-1316:
---------------------------------------
This is still unresolved in 1.10.2 and python 3.7 I get the syntax error
elsewhere, pasting in case that's helpful.
```~ airflow initdb

Would appreciate some advice on how to run this. Again, it's broken on a fresh
installation.
