Erlang安装给erlang模式是错误的

Question

我正在Ubuntu14.04上尝试从灵丹妙药网站上安装Elixir。在执行$ sudo apt-get install esl-erlang时，我会得到以下错误。有人能帮我吗？

$ sudo apt-get install esl-erlang

Answer 1

看起来您同时安装了emacs23和emacs24。当试图为emacs23构建时，会发生故障。除非您出于某种原因真的想要emacs23，否则删除它，然后它应该安装良好：

sudo apt-get remove emacs23

您可能需要手动删除其他一些emacs23 23-*包。

我不知道是什么导致了您的错误，但是您可以尝试使用ASDF和灵丹妙药插件。这允许您安装多个版本的Elixir及其依赖项，并使用希姆斯来使用用户环境，而不是安装到系统目录中。这避免了执行单个系统级安装所带来的许多依赖关系和权限问题。

这个问题只影响到erlang-mode包，它增加了对编辑Emacs中Erlang代码的支持。如果您没有使用Emacs (或者没有在其中开发Erlang )，您可以卸载该软件包：

sudo apt remove erlang-mode

正如在企鹅布莱恩的回答中所指出的，在使用Emacs 23在系统上安装erlang-mode时会发生这种情况，因为erlang-mode只支持Emacs 24或更高版本。(看起来这是包中的一个bug :它不应该尝试为不受支持的Emacs版本编译自己。)如果您想在Emacs中使用erlang-mode，我建议运行Emacs 24并从MELPA安装Erlang模式。
