unable to initialize airflow database after installing airflow - airflow

I installed on a fresh version of airflow using Python 3.7.4 on Mac OS Catalina 10.15.1.
By running:
$ pip install 'apache-airflow[s3,postgres,celery,hdfs,jdbc,hive,slack,crypto,redis]==1.10.4'
When I run:
$ airflow initidb
I get the following error message:
Traceback (most recent call last):
File "/Users/user/opt/anaconda3/bin/airflow", line 21, in <module>

from future import standard_library
ValueError: source code string cannot contain null bytes
I'm wondering if anyone has any suggestions.
Thanks.

I think I figured it out. The future module I had was corrupt, so I just re-installed things and it seems to work now.

You don't mention how you installed RIDE, and I am even surprised it was installed if from PyPi.
Only on today's date (24-june-2022), a development version was updated to run on Python 3.10 (maybe). You can try to install, this one, but be aware of its new bugs.
I can install with:
pip install -U https://github.com/robotframework/RIDE/archive/master.zip
You should browse the RIDE project page here, and look at README, CHANGELOG and Issues. Also see the Slack and Forum links.
