ruby on rails - Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set) -

i'm trying run heroku run rake db:migrate continuously error message:

stopping @ filesystem boundary (git_discovery_across_filesystem not set).

i have seen people type in git init, when type in that, get

reinitialized existing git repository in /home/nitrous/sapp/.git/

to test if has filesystem layout can see if directory holds code mounted filesystem, or if part of project split across filesystems.

you can try setting environmental variable git_discovery_across_filesystem 1 , retry git operation. note: please don't solution until understand both how filesystems layed out , git_discovery_across_filesystem variable does.

on unix it'd like:

export git_discovery_across_filesystem=1

note lack of spaces between variable, =, , 1 -wc
