I am trying to install ipykernel in a separate python 2.7 environment (py27) for use of jupyter notebook. My base environment uses python3.9 that works great. When trying to use conda install ipykernel, I get the error below. Yes, this was done in a separate environment from my base and I am not aware of any virus softwares that are impeding this from successfully completing. Those are the only answers that I've seemed to find online. I also tried reinstalling anaconda. I did not attach the output from conda install -v ipykernel, but saw an error saying invalid syntax in decorator.py on line 162. It was pointing to the file=stderr in a print function call.
Similar to this problem https://github.com/conda/conda/issues/7351, but was unable to solve the problem with the suggestions.
(py27) C:\Users\Heath>conda install ipykernel
