docker - Magit无法连接到docker内的emacsclient？

Question

我正在 docker 中运行 emacs24.5.1(基本镜像是 Ubuntu)。我通过 apt-get 安装了 emacs。此外，我通过melpa安装了magit(magit版本magit-20170702.858)，它很棒。但是，当我尝试提交某些内容时，magit 遇到以下错误:

1 git ? commit -- 
  /usr/bin/emacsclient.emacs24: connect: Connection refused 
  /usr/bin/emacsclient.emacs24: error executing alternate editor 
    "sh -c 'echo "WITH-EDITOR: $$ OPEN $0"; sleep 604800 & sleep=$!; trap "kill $sleep; exit 0" USR1; trap "kill $sleep; exit 1" USR2; wait $sleep'"
error: There was a problem with the editor 
  '/usr/bin/emacsclient.emacs24 --socket-name=/root/.emacs.d/server/server'.
Please supply the message using either -m or -F option.

当我尝试手动启动 emacsclient 时，emacsclient 出现错误:

/usr/bin/emacsclient.emacs24 --socket-name=/root/.emacs.d/server/server tmp.make
/usr/bin/emacsclient.emacs24: connect: Connection refused
/usr/bin/emacsclient.emacs24: error accessing socket "/root/.emacs.d/server/server"

这表明这实际上并不是一个 Magit 错误，而是一个 emacsclient 错误，而且实际上它可能正在发生，因为我在 docker 内运行，尽管我对此不确定。

有谁知道如何启动 emacsclient 或绕过 magit 中 emacsclient 的要求。曾经有一个插件模式可以绕过 magit 内的 emacsclient，但不久前它已被弃用并从 melpa 中删除，所以我不太热衷于尝试它。

更新 emacs --daemon 在 docker 内启动没有问题，但 magit commit 仍然不起作用，所以也许这根本不是 docker 问题？

emacs --daemon

 Emacs might crash when run in daemon mode and the X11 connection is unexpectedly lost. 
 Using an Emacs configured with --with-x-toolkit=lucid does not have this problem.

仔细检查您的基础镜像:this thread报告看到相同的错误消息:

I managed to figure out the problem. I had byte compiled the emacs code with emacs24, and loading that in emacs23 caused all heck to break loose.
With the byte compilation done with a matching version of emacs, the test suite passes.

您可以find here an example of building a docker image使用 emacs，来自 various distro (包括 Ubuntu 16.04)。
Emacs(23，替换为您的版本)is installed as :

export DEBIAN_FRONTEND=noninteractive
test $1 = 7.11 && emacs=emacs23-nox || emacs=emacs-nox
apt-get update
apt-get install -y -q build-essential git \
    libxapian-dev libgmime-2.6-dev libtalloc-dev \
    zlib1g-dev python-sphinx man dtach $emacs gdb gpgsm
apt-get -y autoremove
apt-get -y clean
rm -rf /var/lib/apt/lists/
