I'm using Robotframework for UI testing and robotidy for autoformatting Robot Framework code with Python 3.10.2.

robotidy --config pyproject.toml --check --diff .

It works in typing_extensions 4.12.2, but raises TypeError: typing._GenericAlias.__init__() got multiple values for keyword argument '_typevar_types' with typing_extensions 4.13.0.

Error msg :

$ robotidy --config pyproject.toml --check --diff .

Thank you for reporting. The fix should be fairly simple by using the new keywords only for 3.10.3+ in which typing._ConcatenateGenericAlias.__init__ was removed. I am on it.

@robertchang961 I've added the fix in the linked PR. If you do not want to wait you can fix it manually by:

  • +/- 1 your python version
  • change line 2075 in your typing_extensions source code: 
    -if sys.version_info >= (3, 10, 2):
+if sys.version_info >= (3, 10, 3):
