Adapt Learning Community: Plugins not installing

I am receiving the following error when attempting to install. Can anyone help me? I'm not very technical but I am SO CLOSE!!!

From terminal:

---------------

Completed the npm install.

Installing plugins for the Adapt framework.

Oh dear, something went wrong. I'm terribly sorry. EACCES, unlink '/Users/ericrohrer/.cache/bower/registry/adapt-bower-repository.herokuapp.com/lookup/adapt-contrib-vanilla_73013'

ERROR: 1

Framework install failed. See console output for possible reasons.

Hello Eric,

I'm not certain of the specific error that you are receiving, but an EACCES error refers to a permission denied response when deleting '/Users/ericrohrer/.cache/bower/registry/adapt-bower-repository.herokuapp.com/lookup/adapt-contrib-vanilla_73013'

Can you check that you have granted yourself elevated user permissions on the /usr/local directory as documented here, (alternately you can prefix the install command with 'sudo').
