I am trying to install a conda package that appears to require Python 3.7. My base environment uses Python 3.8. I successfully created and activated a virtual environment with version 3.7. However, when I try to install that package in the environment, I still get the error below. How can I solve this problem to successfully install this package?

(venv)(base)C:\Users\MyUsername> python Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

(venv)(base)C:\Users\MyUsername> conda install arcpy -c esri UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment:

Specifications:

  • arcpy -> python[version='>=3.7,<3.8.0a0']

Your python: python=3.8

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. Note that conda will not change your python version to a different minor version unless you explicitly specify that.

  • Is Anaconda installed to your venv or are you using it globally? – nonamorando Jun 22 '21 at 20:47
  • I believe I am using it globally? I am new to this, but I have been using Spyder with Anaconda for a few months – justabeginner Jun 22 '21 at 20:52
  • I just tried "pip install conda" in the venv, but that errored stating that conda can only be used in root environments – justabeginner Jun 22 '21 at 21:00
  • You're right... try `conda install python=3.7` – nonamorando Jun 22 '21 at 21:53
  • That yields a PackagesNotFoundError. Does this mean python 3.7 isn't installed on my computer? It looks like it is, and I was able to create the venv with that version – justabeginner Jun 22 '21 at 22:14
  • It's cause Anaconda is using your global Python package, not your venv one. I don't know the answer, but this may help: https://stackoverflow.com/questions/42075581/conda-install-python-3-6-unsatisfiableerror – nonamorando Jun 23 '21 at 00:05
  • Did you ever solve this? I am having a similar problem with installing the ArcGIS API for Python. – Foggy Feb 17 '22 at 18:50
  • @Foggy I did not. What is the exact error you are receiving? – justabeginner Feb 18 '22 at 20:31
  • @justabeginner - I suspect my root environment was corrupted. No matter what I tried the installation failed. I tried again on a different computer with a newer installation Anaconda installation and the installation proceeded as expected. I haven’t finished retrying on the original corrupted installation yet. I am restarting wit a new install of anaconda there. – Foggy Feb 20 '22 at 03:45
  • @justabeginner The issue did not resolve with a fresh install. `UnsatisfiableError: Note that strict channel priority may have removed packages required for satisfiability.` I don't see any way forward on this. Moving this to an ESRI forum question. – Foggy Feb 22 '22 at 22:07
