I am trying to use yarn in offline mode because the build server I am using does not have access to yarn registry or github.com.
I found this article on how to use yarn in offline mode which works great until I added node-sass.
It appears even if you use yarn install --offline, node-sass will go to github.com to download libsass.
Is there a way to instruct node-sass to use an offline version of libsass instead of going to github.com?
