I am trying to create an environment based on a .yml file, the name of the file is env.yml . I run the following snippet on terminal:

conda env create -f env.yml

Then anaconda starts installing all packages outlined in the .yml file, until it gets to packages installed with pip. It raises the following error:

Ran pip subprocess with arguments:
['/Users/danielribeiro/opt/anaconda3/envs/lz_env/bin/python', '-m', 'pip', 'install', '-U', '-r', '/Users/danielribeiro/opt/Python/condaenv.80zhk806.requirements.txt']
Pip subprocess output:
Collecting backports-lzma==0.0.13 (from -r /Users/danielribeiro/opt/Python/condaenv.80zhk806.requirements.txt (line 1))

Pip subprocess error:
  Could not find a version that satisfies the requirement backports-lzma==0.0.13 (from -r /Users/danielribeiro/opt/Python/condaenv.80zhk806.requirements.txt (line 1)) (from versions: )
No matching distribution found for backports-lzma==0.0.13 (from -r /Users/danielribeiro/opt/Python/condaenv.80zhk806.requirements.txt (line 1))


CondaEnvException: Pip failed

I am not sure why the package backport-lzma==0.0.13 is not installing. I also try installing it manually with

conda activate lz_env
pip install backports-lzma==0.0.13


Collecting backports-lzma==0.0.13
  Could not find a version that satisfies the requirement backports-lzma==0.0.13 (from versions: )
No matching distribution found for backports-lzma==0.0.13

How do I make sure I can create the environment 'lz_env' based on the .yml file I have with all the packages contained in the file?

the .yml file is the following:

To solve the problem, I just installed the most current version of backports-lzma by manually downloading the package into my machine, then ran the command outlined in their documentation website:

conda install -c conda-forge backports.lzma

And it worked, it installed the 0.0.14 version and the version I intended to install was 0.0.13, but for the program I'm running 0.0.14 worked fine!

You can remove the version number from "backports-lzma==0.0.13" in your yml file. and change it to "backports-lzma". The installer will look for the default version available to it from the channels provided. Can do the same for any such error for any distribution or package.
