Hi,

Coming late to this fray and responding to original Subject

If you

(require 'use-package)

Then you might find the following to work, as I do:

(use-package org

  :ensure org-plus-contrib                             ; following http://emacs.stackexchange.com/questions/7890/org-plus-contrib-and-org-with-require-or-use-package

;; .. etc

)

YMMV,

Malcolm

Subject: Re: [O] is it bad to have both org and org-plus-contrib installed?

Hi all,

I just discovered a bug in this advice that I suggested earlier in this thread.. I needed to fix the order of packages in the new-ret list that is returned. The bug was that the order of pkgs in new-ret was flipped compared to that in orig-ret.. so I needed to flip it back using reverse.

So just for record, here is the fixed function:

;; http://emacs.stackexchange.com/a/26513/115

(defun modi/package-dependency-check-ignore (orig-ret)

  "Remove the `black listed packages' from ORIG-RET.

Packages listed in the let-bound `pkg-black-list' will not be auto-installed

even if they are found as dependencies.

It is known that this advice is not effective when installed packages

asynchronously using `paradox'. Below is effective on synchronous

package installations."

  (let ((pkg-black-list '(org))

        new-ret

        pkg-name)

    (dolist (pkg-struct orig-ret)

      (setq pkg-name (package-desc-name pkg-struct))

      (if (member pkg-name pkg-black-list)

          (message (concat "Package `%s' will not be installed. "

                           "See `modi/package-dependency-check-ignore'.")

                   pkg-name)

        (push pkg-struct new-ret)))

    ;; Tue Apr 11 17:48:16 EDT 2017 - kmodi

    ;; It's *very* critical that the order of packages stays the same in NEW-RET

    ;; as in ORIG-RET. The `push' command flips the order, so use `reverse'

    ;; to flip the order back to the original.

    ;;   Without this step, you will get errors like below when installing

    ;; packages with dependencies:

    ;;   Debugger entered--Lisp error: (error "Unable to activate package ‘nim-mode’.

    ;;   Required package ‘flycheck-28’ is unavailable")

    (setq new-ret (reverse new-ret))

    new-ret))

(advice-add 'package-compute-transaction :filter-return #'modi/package-dependency-check-ignore)

I've run into the same problem with Spacemacs and would welcome a
solution.

All the best,
