I just installed GNU Emacs 23.1.1 on a new machine and copied my ~/.emacs and ~/.emacs.d/ from another machine where I'm running emacs 25.1.1.

When I launch emacs it writes Error (initialization): User <my_id> has no home directory into a buffer. Not surprisingly, it also has not read .emacs.

One thing odd about this machine is that home directories are stored in /home/, rather than in /mxhome/ like in the rest of my work environment, and this new machine has a symlink from /mxhome -> /home. I don't know if that is important.

UPDATE: launching with emacs -q -l /home/my_id/.emacs filename loads the .emacs file and avoids the error, although I don't know if it solves the problem entirely.

Emacs administration is largely a mystery to me. Can anyone help?

  • Do you still see the problem with emacs --no-site-file? – Stefan Jul 7 '17 at 23:27
  • Do you have a HOME environment variable set? If not, try setting HOME. – Drew Jul 7 '17 at 23:54
  • @Stefan @Drew I still see the problem with emacs --no-site-file. I do have HOME set to /mxhome/my_id which, as noted above, is a symlink. – Chap Jul 8 '17 at 0:05

Following the idea from @glucas, I debugged the variable init-file-user, and came up with a temporary solution

alias emacs='emacs --user ""'

With --user '', it enforced the init-file-user to be an empty string, then 

(file-directory-p (expand-file-name (concat "~" init-file-user)))

would be properly evaluated to the correct path.

My case is really odd, and I've tried emacs-25.2, 25.3 and 26.1. They all produce the same problem. However, this problem only appears on CentOS7, but not CentOS6. So, I compared the difference in the value of init-file-user between the two systems, and came up with the above solution. On CentOS6, init-file-user is an empty string, emacs works; but on CentOS7, it's , producing error.

I still don't know how the value of init-file-user is initialized, the source code for startup.el is rather overwhelming.

    Over a year later and I'm just getting back to this. Using --user "" solves my problem, or at least works around it as you described. – Chap Nov 6 '18 at 23:03

I would try starting emacs with HOME set to /home/my_id (rather than the symlink), since explicitly using that path seems to work.

The error message ("user has no home directory") is coming from startup.el. You may be able to use --debug-init to investigate further.

Basically the error message implies the following is false:

(file-directory-p (expand-file-name (concat "~" init-file-user)))

You could try starting Emacs with your workaround and evaluate (expand-file-name "~") and (file-directory-p (expand-file-name "~")) and see if they are returning what you'd expect.

    env HOME=/home/my_id emacs still throws the error. Then evaluating (expand-file-name "~") gives /mxhome/my_id, oddly. And, evaluating (file-directory-p (expand-file-name (concat "~" init-file-user))) is indeed nil. I will try using --debug-init. – Chap Jul 8 '17 at 1:55
  • Does (expand-file-name (concat "~" init-file-user)) give you /home/my_id/~my_id or something like that. That's what I see with the same error message. I don't have fix yet – zyxue Aug 25 '17 at 15:58
  • @zyxue it gives "/home/my_id" – Chap Mar 27 '18 at 15:19
  • Also, I found that init-file-user is nil – Chap Mar 27 '18 at 15:25

Change your home path. If your computer's OS is Windows.You can check the regedit. The path is: HKEY_LOCAL_MACHINE\SOFTWARE\GNU\Emacs\Home Change it to your Emacs location.

  • It is much easier to set the environment variable HOME in this case. – theldoria Aug 12 '17 at 6:27
