Summary

SDK-based packages installation fails due to an update to setuptools and the fact that some dependencies (simpleeval) use a deprecated setuptools feature, namely use_2to3.

Steps to reproduce

Have an SDK-based tap or target package (that depends on singer_sdk>=0.3.0), try a clean install and it will fail.

What is the current bug behavior?

SDK-based packages depending on singer_sdk>=0.3.0 can't be installed.

• setuptools issue that prompted the break: [BUG] Should fail hard when installing packages that want 2to3 pypa/setuptools#2769
• use_2to3 in simpleeval: https://github.com/danthedeckie/simpleeval/blob/master/setup.py#L18

What is the expected correct behavior?

SDK-based packages can be installed with a recent SDK version.

Possible fixes

Remove dependency on simpleeval (last released Nov 2019) and replace with an alternative that doesn't break installation.

Temporary workaround:

Users can pin setuptools to <58.0.0 in their system Python and/or virtualenvs.
