The try it https://www.singer.io/#what-it-is code on singer.io doesn't work

After installing pip3 install target-csv tap-exchangeratesapi

Executing tap-exchangeratesapi | target-csv

Throws the below error:

Traceback (most recent call last):
  File "/usr/local/bin/tap-exchangeratesapi", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.7/site-packages/tap_exchangeratesapi/__init__.py", line 113, in main
    start_date = singer.utils.strptime_with_tz(start_date).date().strftime(DATE_FORMAT)
AttributeError: module 'singer.utils' has no attribute 'strptime_with_tz'

It doesn't work on Ubuntu Linux 19.10 either, but for different reasons: python3.7 -m venv venv-target-csv . venv-target-csv/bin/activate pip install target-csv tap-exchangeratesapi tap-exchangeratesapi | target-csv

During handling of the above exception, another exception occurred:

It doesn't work in Docker's python container, either, but at least it installs:

docker container run -it python /bin/bash deactivate; rm -rf venv-target-csv/ ; python3.8 -m venv venv-target-csv/ ; . venv-target-csv/bin/activate ; pip install --upgrade pip ; pip install wheel; pip install target-csv deactivate; rm -rf venv-tap-exchangeratesapi/ ; python3.8 -m venv venv-tap-exchangeratesapi/ ; . venv-tap-exchangeratesapi/bin/activate ; pip install --upgrade pip ; pip install wheel; pip install tap-exchangeratesapi ; tap-exchangeratesapi >/dev/null

result: headers but no numbers

venv-tap-exchangeratesapi/bin/tap-exchangeratesapi | venv-target-csv/bin/python venv-target-csv/bin/target-csv

result: silent failure, no file exchange_rates.csv

Installing the tap and targets in separate virtual environments fixes this issue, but then you get:

Traceback (most recent call last):
  File "/Users/dean/.virtualenvs/tap-exchangeratesapi/bin/tap-exchangeratesapi", line 8, in <module>
    sys.exit(main())
  File "/Users/dean/.virtualenvs/tap-exchangeratesapi/lib/python3.8/site-packages/tap_exchangeratesapi/__init__.py", line 116, in main
    do_sync(config.get('base', 'USD'), start_date)
  File "/Users/dean/.virtualenvs/tap-exchangeratesapi/lib/python3.8/site-packages/tap_exchangeratesapi/__init__.py", line 65, in do_sync
    for rate in payload['rates']:
KeyError: 'rates'

When I inspect payload I see:

{'success': False, 'error': {'code': 101, 'type': 'missing_access_key', 'info': 'You have not supplied an API Access Key. [Required format: access_key=YOUR_ACCESS_KEY]'}}

Given that this "try it" code is many people's first exposure to singer, it really seems like it should be switched to a different tap.
