I can't create a python 3.8 environment in anaconda

Question

I'm new to the community so thank you for any support you could give me. My question:

I tried to create a new anaconda environment for python 3.8 with

(base) C:\Users\user>conda create -n My_Env_py38 python=3.8 anaconda

After it tries to solve the environment it fails and I get the following message:

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

Package python conflicts for:

I've updated anaconda. (And it has been working fine with python 3.7.6 before and after the update) I've also tried to install python 3.8 in the current environment and anaconda can't solve the environment either. Any ideas?

Thank you

Answer 1

I finally created a new environment from the Anaconda navigator; I didn't specify the python version, so it created it with python 3.7.6. Then (again from the navigator) I updated the python version (to 3.8.1); it seems to work fine. For some reason it hadn't worked before when I tried to update the existing environment or to create a new one from the command prompt; not sure if it's possible now, but this alternative worked.
