Expected Behavior

After adding the postinstall script in package.json ("postinstall": "react-flagpack --framework gatsby") and running npm install, the flags should be copied into a static/flags folder.

Current Behavior

Instead, the following error shows up, denoting a lack of "/static" directory. Note that "cd static" works as obviously the directory exists, but my guess is the / in front is causing the issue.

info React flagpack is copying flags to /static/flags
error React flagpack failed to copy flags
[Error: ENOENT: no such file or directory, mkdir '/static'] {
errno: -2,
code: 'ENOENT',
syscall: 'mkdir',
path: '/static'
}
