ImportError on typing_extensions

[DeltaSigma130]

Using the following versions:

python  3.9.1
mypy                   0.812
mypy-extensions        0.4.3
typed-ast              1.4.2
typing-extensions      3.7.4.3
typing-inspect         0.7.1

I get the following import error. I saw a the pull request #76, but it doesn't look like simply moving typing-extensions to 3.7.4.2 will solve it.

Updating typing_extensions to >= 3.10.0 solves the issue.
