warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

Solution 1:

You will need to have root access to do this. If you aren't already the administrative user, login as the administrator. Then use 'sudo' to change the permissions:

sudo chmod go-w /usr/local/bin

Obviously, that will mean you can no longer install material in /usr/local/bin except via 'sudo', but you probably shouldn't be doing that anyway.

Solution 2:

I had the same error here MacOSX 10.6.8 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.

so I had to do

sudo chmod 775 /usr/local

to get rid of the warning.

A question here is does any non root:wheel process in MacOS need to create anything in /usr/local ?
