I have resolved this issue, it was an issue with env variables.
I have performed a fresh installation of conda in preparation for the new 2018 version of the api however i have been having some trouble with installing the conda packages.
Where previously there were tar files within the miniconda/pkgs directory there are now just directories, as such i am unable to run the 'conda install' command.
Attempting the command on the directory (since there is no tar file) just leads to the below output:
conda install csd-python-api-1.5.1-mac-64-py2.7-conda
Solving environment: failed
PackagesNotFoundError: The following packages are not available from current channels:
Is the lack of tar files an issue with the latest OSx release or am I missing something that has been changed in the process?
