warning: Insecure world writable dir when I run a ruby or gem command

Not sure why I'm getting this, but I just installed RVM, the new Ruby 1.9, and reinstalled a bunch of gems, and I get this

/Users/johnsmith/.rv开发者_如何转开发m/rubies/ruby-1.9.1-p378/bin/gem:4: warning: Insecure world writable dir /opt/local/bin in PATH, mode 040777

Everything still runs otherwise, but I was wondering if there was a way I could get rid of it.

Just chmod go-w /opt/local/bin at a shell prompt (depending on permissions you may need to sudo to do that).

To clarify, whatever path returns after it says insecure world writeable, is what you use.

So instead of: chmod go-w /opt/local/bin you would replace /opt/local/bin with whatever your path is.

Find your gem path so we can edit the bundler gem. Execute the following in your shell:

$ ruby -r rubygems -e "p Gem.path"

Navigate to your gem path and cd into the version of bundler currently being used. Now navigate to lib -> bundler and open runtime.rb in your favorite text editor. Add “$VERBOSE = nil” to line 2.

require "digest/sha1" 
$VERBOSE = nil 
module Bundler   
class Runtime < Environment
    include SharedHelpers

    def setup(*groups)
      # Has to happen first
      clean_load_path

...

In some cases (like mine), the stack goes deeper than opt/local/bin. In that case, use

sudo chmod go-w opt/local/*/bin usr/local/*/bin opt/local/bin usr/local/bin

In any case, the error prompts where the insecure world is.

If your environment does not allow you to fix this error properly (i.e. ruby lives on a network share or some such), see this answer for a way to suppress the error.
