Why target-csv project depend on singer-python==2.1.4 while current singer-python version is v5.8.1 ?

Best regards,

We pinned the versions of dependancies to whatever works at the time off writing the target. Since there's no reason to bump the singer-python version, we didn't.

If this is an issue you run into while trying to run the target with newer taps, please set up the target and the tap in their own virtual environments.

Hi!
Yes, this is actually a bigger issue, given that even a command advertised on a main website https://www.singer.io/#what-it-is is not working any longer:

> pip install target-csv tap-exchangeratesapi
> tap-exchangeratesapi | target-csv

won't work, as target-csv and tap-exchangeratesapi require different versions of singer-python.

More details:

$ docker run -it python:3 /bin/bash

Collecting target-csv
  Downloading target-csv-0.3.0.tar.gz (4.0 kB)
Collecting tap-exchangeratesapi
  Downloading tap-exchangeratesapi-0.1.1.tar.gz (2.4 kB)
...
tap-exchangeratesapi 0.1.1 requires singer-python==5.3.3, but you'll have singer-python 2.1.4 which is incompatible.

An issue was wrongly opened for singer-io/tap-exchangeratesapi#6 on that, but it's better to update target-csv.

If you don't mind, please update it. It's the best practice to update software to the latest versions.

Possibly can be solved by running tap-exchangeratesapi and target-csv in separate virtual environments.

python3 -m venv ~/.virtualenvs/tap-exchangeratesapi
source ~/.virtualenvs/tap-exchangeratesapi/bin/activate
pip install tap-exchangeratesapi
deactivate

python3 -m venv ~/.virtualenvs/target-csv
source ~/.virtualenvs/target-csv/bin/activate
pip install target-csv
deactivate

~/.virtualenvs/tap-exchangeratesapi/bin/tap-exchangeratesapi | ~/.virtualenvs/target-csv/bin/target-csv

I think the root problem are some changes in the exchangerates API keys.
Even with 2 venv I am getting
KeyError: 'rates'.
