Emacs：Ansi-term不是制表符

Question

I have recently installed a few packages so that I can program iOS apps from emacs, but I am having some trouble. One of the packages (I'm pretty sure it's autocomplete) is preventing tab-completion from working in ansi-term. Any time I try to tab-complete, I get the error "Wrong type argument: characterp, tab".

Here is my .emacs file:

; Add packages
(add-to-list 'load-path "~/.emacs.d/elpa")
(add-to-list 'load-path "~/.emacs.d/packages")

(require 'package)

; Package sources
(add-to-list 'package-archives 
    '("marmalade" .
      "http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives
    '("melpa" .
            "http://melpa.milkbox.net/packages/") t)

(package-initialize)

; Check packages were loaded
(require 'linum-relative)
(require 'git-gutter-fringe)
(require 'yasnippet)
(require 'auto-complete-config)

; Enable packages

Alright, I fixed it. The problem was with yasnippets, but the suggestion on the link didn't work. For some reason setting yas-minor-mode to -1 didn't work. What I had to do was set yas-dont-activate to something.

Suggested fix that did NOT work for me:

(add-hook 'term-mode-hook (lambda()
                (yas-minor-mode -1)))

What DID work for me:

(add-hook 'term-mode-hook (lambda()
        (setq yas-dont-activate t)))

I'm running emacs 23.4.1

Answer 2

The method provided by user1539179 works by inactiving yasnippets mode while using the shell mode. There is a small problem that I can no longer use the yasnippet mode after I open ansi-term. For example, if a markdown file is opened after the ansi-term, the yasnippet will not work. My solution is not using yasnippet globally, but hook to the mode we want to. Here is my emacs configure for yasnippet that I only bind it to prog-mode , ess-mode , and markdown-mode , and the tab-completing works in ansi-term.

(require 'yasnippet)
(yas-reload-all)
(add-hook 'prog-mode-hook 'yas-minor-mode)
(add-hook 'ess-mode-hook 'yas-minor-mode)
(add-hook 'markdown-mode-hook 'yas-minor-mode)
