问题描述
使用钢筋释放时，我必须设置一个环境变量。这是一个节点列表。例如：
When using rebar for release, I have to set an environment variable. It is a node list. For example:
vm.args
# -zarah cluster_nodes ['zarah_slave_a@yus-iMac.local','zarah_slave_b@yus-iMac.local','emacs@yus-iMac.local']
但是运行时，shell会给出错误消息：
But when running, the shell gives the error message:
＊＊＊＊＊＊＊＊＊＊＊＊＊
{error_logger,{{2013,11,20},{10,47,28}},"application_controller: ~ts: ~ts~n",[["syntax error before: ","'.'"],"[zarah_slave_a@yus-iMac.local,zarah_slave_b@yus-iMac.local,emacs@yus-iMac.local]"]}
Erlang R16B02 (erts-5.10.3) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:fals
我认为这是由。引起的问题。在节点名称中。
I think it is the problem cause by "." in the node name. How to deal with it?
推荐答案
在单引号之前添加双引号，它将起作用。
Add a double quote before the single quote and it will work.
-zarah cluster_nodes ["'zarah_slave_a@yus-iMac.local'","'zarah_slave_b@yusiMac.local'","'emacs@yus-iMac.local'"]
