---------------------------------------
Summary: Flask 1.1.0 release breaks airflow 1.10.3
Key: AIRFLOW-4902
URL: https://issues.apache.org/jira/browse/AIRFLOW-4902
Project: Apache Airflow
Issue Type: Bug
Components: cli
Affects Versions: 1.10.3
Reporter: Catarina Silva
When setting up an environment by installing airflow 1.10.3, the new version of
flask breaks airflow:
*Command ran:*
{{pip install
apache-airflow[crypto,kubernetes,postgres,hive,jdbc,ssh,s3]==1.10.3}}
*Installation output:*
{{ERROR: apache-airflow 1.10.3 has requirement jinja2<=2.10.0,>=2.7.3, but
you'll have jinja2 2.10.1 which is incompatible.}}
{{ERROR: apache-airflow 1.10.3 has requirement werkzeug<0.15.0,>=0.14.1, but
you'll have werkzeug 0.15.4 which is incompatible.}}
*Command ran:*
{{airflow initdb}}
*Output:*

{{ from werkzeug.wrappers.json import JSONMixin as _JSONMixin}}
{{ModuleNotFoundError: No module named 'werkzeug.wrappers.json';
'werkzeug.wrappers' is not a package}}
{{After forcing flask to 1.0.4 the command "airflow initdb" works. I believe
removing the restriction of werkzeug version might solve this problem, since
the warning at installation seems to point to that}}
note: not sure which priority to assign to this, added major since it breaks
without explicitly adding the flask version
