Projectile installed but “Autoloading failed to define function projectile-mode”

Question

I can M-x projectile-mode (I get this and other projectile commands in the completion list) but it fails with

Autoloading failed to define function projectile-mode

Projectile is an installed package, according to package-list-packages:

projectile 20150724.1312 installed

(And I can use C-h f to search for the function and to open the projectile.el file.)

When I add (require 'projectile) to my init.el, startup fails with

error: Required feature `projectile' was not provided

Emacs 24.5 on OSX installed via Homebrew, using the Emacs Live (git rev 170bddd, 2015-07-18) setup. Here is my Emacs config (as an Emacs Live pack).

Any help would be appreciated. Thank you!

Answer 1

You got the error "Autoloading failed to define function" because multiple packages are apparently active in your load-path. Try M-x list-load-path-shadows to get a clue which packages are conflicting.
