Cannot be installed in an environment with Python 3.9

Python cannot be installed on a conda environment with Python 3.9

What steps will reproduce the problem?

1. Download Conda (Anaconda/Miniconda)
2. Create a python 3.9(.2) environment and activate it
3. Run conda install spyder-terminal -c spyder-ide

What is the expected output? What do you see instead? I expect spyder-terminal to successfully install. I instead see the following error:

Specifications:

  - spyder-terminal -> python[version='3.5.*|3.6.*|>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.8,<3.9.0a0|>=3.7,<3.8.0a0']

Your python: python=3.9

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to.

Versions and main components

• Terminal Version: Conda 4.9.2
• Spyder Version: Spyder 4.2.5
• Python Version: Python 3.9.2
• Operating system: Windows 10

Hi @DragonEggBedrockBreaking,

We just released spyder-terminal 1.0.0 available for Python 3.9 in pip and in conda-forge channel. Please take into account that you need to install Spyder 5.0.5 to use it.

Thanks for reporting!

Hi @DragonEggBedrockBreaking,

This error pops out in a new and clean environment or did you installed something before in it?

I think it was clean, but I don’t remember. I will test tomorrow (on python 3.9.4) on a new clean environment.
