There can be another reason for the 'ResolvePackageNotFound' error -- the version of the packages you require might be in an old version of the repository that is not searched by default.

The different paths to locations in the Anaconda repositories can be found at:
https://repo.continuum.io/pkgs/

My yml file [NW_BI.yml] is as follows:

name: NW_BI
channels:
- 'https://repo.continuum.io/pkgs/free' # Remove this line and it fails!!!
- conda-forge
- defaults
dependencies:
- python=2.7.10
- pandas=0.16.2
- pyodbc=3.0.10

Create using:

conda env create -f 'path to file'\NW_BI.yml

I wanted to recreate an old environment!!!!
