Bash on Win10 的 elixir 安装过程中会出现如下错误：
/usr/local/bin/elixir: 126: exec: erl: Is a directory
这是由于 esl-erlang 的 19.0 版本和 bash 不兼容所致。
可行的解决方案为安装 18.3，也就是18的最新版。
I've installed it like that:
安装方案如下：
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb && sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
sudo apt-get install esl-erlang=1:18.3
sudo rm /usr/bin/erl
sudo ln -s /usr/lib/erlang/bin/erl /usr/bin/erl
sudo apt-get install elixir
And it works on the official 14393 build, had to fix the simlink like @Andorbal suggested
The esl-erlang build which doesn't seem to work on "bash on windows" is 19.0.2
