QIIME2-2017.2 installation

Hi @Aditya_Bandla, it looks like you might accidentally be using the Mac OS X installation commands, instead of the linux installation commands (as @ebolyen mentioned above). If you are trying to install QIIME 2 on a linux machine, you will need to use the linux installation instructions. So ultimately this would look like the following, to get the latest versions of QIIME 2 and gneiss:

# These first two might be optional, depending on how far you got earlier
$ source deactivate qiime2-2017.6
$ conda env remove -n qiime2-2017.6
# The following steps are not optional
$ conda create -n qiime2-2017.6 --file https://data.qiime2.org/distro/core/qiime2-2017.6-conda-linux-64.txt
$ source activate qiime2-2017.6
$ conda install -c biocore gneiss
