安装erlang
方法一：在linux下直接安装
运行以下命令直接安装
sudo apt-get install erlang
存在的问题：可能是低版本Erlang。
可运行以下命令查看erlang版本：
erl --version
方法二：通过esl安装
通过方案一安装后升级版本可能需要执行的脚本
sudo apt-get autoremove --purge erlang-base
首先要去Erlang官网下载一个最新的安装包。
不推荐通过apt-get会发现找不到源，或者很久没有更新，安装的都是老旧的。
执行安装操作
1、执行安装操作
dpkg -i esl-erlang_21.0-1_ubuntu_artful_amd64.deb
它会说，我缺少很多相关的依赖。
root@ubuntu:/home/erlang# dpkg -i esl-erlang_21.0-1_ubuntu_artful_amd64.deb
Selecting previously unselected package esl-erlang.

dpkg: dependency problems prevent configuration of esl-erlang:
esl-erlang depends on libwxbase2.8-0 | libwxbase3.0-0 | libwxbase3.0-0v5; however:
Package libwxbase2.8-0 is not installed.
Package libwxbase3.0-0 is not installed.
Package libwxbase3.0-0v5 is not installed.
esl-erlang depends on libwxgtk2.8-0 | libwxgtk3.0-0 | libwxgtk3.0-0v5; however:
Package libwxgtk2.8-0 is not installed.
Package libwxgtk3.0-0 is not installed.
Package libwxgtk3.0-0v5 is not installed.
esl-erlang depends on libsctp1; however:
Package libsctp1 is not installed.dpkg: error processing package esl-erlang (–install):
dependency problems - leaving unconfigured
Errors were encountered while processing:

2、 按照要求解决依赖
apt-get install libwxbase3.0-0v5
例如：
root@ubuntu:/home/erlang# apt-get install libwxbase3.0-0v5
Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run ‘apt-get -f install’ to correct these:
The following packages have unmet dependencies:
esl-erlang : Depends: libwxgtk2.8-0 but it is not installable or
libwxgtk3.0-0 but it is not installable or
libwxgtk3.0-0v5 but it is not going to be installed
Depends: libsctp1 but it is not going to be installed
Recommends: erlang-mode but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).
这个时候你需要执行：
apt-get -f install
然后会让你同意输入一个y。
大概需要五分钟去执行。
3、再次执行安装操作
dpkg -i esl-erlang_21.0-1_ubuntu_artful_amd64.deb
root@ubuntu:/home/erlang# dpkg -i esl-erlang_21.0-1_ubuntu_artful_amd64.deb

4、查是否安装成功
erl
这样就安装成功了。
root@ubuntu:/home/erlang# erl
