Hello,
I am on Windows 10, and I installed Psi4 v1.6.0 (stable release) using Anaconda. To walk you through what I did, I installed Psi4 by typing the following into the Anaconda prompt:
conda create -n p4 psi4 python=3.8 -c psi4 -c conda-forge
I then activated the environment and ran psi4 --test. Here is the result:
Traceback (most recent call last):

keywords: Dict[str, Any] = Field(default_factory=dict, description=“The keywords to use in the computation.”)
TypeError: Field() missing 1 required positional argument: ‘default’
Does anyone know what can be causing this TypeError? As far as I know, this error generally comes up when trying to call a method of a class which has not been instantiated, where in this case, the class is Field(), which belongs to the pydantic package. But I’m not sure how to go about correcting this.
In case it may be useful, here is what I get when I run psi4 --psiapi:
export PATH=C:/tools/miniconda3:$PATH # python interpreter
export PATH=C:\Users\Moe\anaconda3\envs\p4\bin:$PATH # psi4 executable
export PYTHONPATH=C:\Users\Moe\anaconda3\envs\p4\lib/:$PYTHONPATH # psi4 pymodule
