问题
I am trying to install packages in a python 3.6.3 virtual environment. I keep getting errors.
I have tried pip with --ignore-installed flag like: pip install -I -r package-list.txt.
Here is part of what I have in package-list.txt.

With first package _libgcc_mutex==0.1==main I get this error:
Ignoring pip: markers 'python_version < "3"' don't match your environment
ERROR: Invalid requirement: '_libgcc_mutex==0.1==main' (from line 4 of package-list3.txt)
Without _libgcc_mutex==0.1==main I get:
Ignoring pip: markers 'python_version < "3"' don't match your environment

Your file states in the comment section that it is supposed to be used with conda, it is not a requirements.txt but a yml file. Try using the command listed in the file:
conda create --name <env> --file <this file>
If you want to modify your current environment based on that file, try (while inside of your environment):
conda env update --file <your file>
