Unable to install library

[dino340]

With a fresh install of Anaconda3, and freshly cloned git repo I have navigated into the folder containing the environment.yml file and run the conda env create -f environment.yml command in git bash, once it runs it finds conflicts for many packages and when it completes running the source activate conda-slicemypdf command gives an error of

Could not find conda environment: conda-slicemypdf
You can list all discoverable environments with `conda info --envs`.

I am unsure what I am doing wrong here as the environment.yml file seems to not be creating the environment.
