Hello, were you able to figure this out? I am having the same issue. I somehow got it to work yesterday but am stuck with the issue again today. I tried the answer `pip install python-dateutil` but no luck. — Austin, Apr 22 '20 at 23:04

python -m pip install --upgrade python-dateutil

Upgrading python-dateutil solve the problem for me. On my machine, 2.5.3 to 2.8.1.

Skimming the source code, I found out that UTC variable is added in 2.7.0. So, I think any version >= 2.7.0 will solve the issue.

#: Convenience constant providing a :class:`tzutc()` instance

#: .. versionadded:: 2.7.0
UTC = tzutc()

Got a similar issue while trying to copy files from AWS S3 using aws cli. Running pip install python-dateutil updated the python-dateutil to 2.8.1 and it works well now.

Try to specify the python-dateutil version and install it before the package which has a error, in your case zappa exempla:

 pip install python-dateutil==2.8.1 zappa

my case the package which i was getting a erro was freezegun, so i ran

pip install python-dateutil==2.8.1 freezegun==0.3.15

and it worked

I had this issue where trying to run eb deploy for AWS Elastic Beanstalk.

What worked for me was: sudo pip3 install python-dateutil --upgrade

(note: running this without sudo did not fix the issue)

For reference this was the error I was getting prior to this:

eb deploy projectFoo
Deploying to development environment
Deploying to AWS
Creating application version archive "app-200711_113503".
Uploading projectFoo/app-200711_113503.zip to S3. This may take a while.
Upload Complete.
