Erlang Ejabberd iex实况转播'；“坏的”；K"；值：\'；错误

我正确安装了

ejabberd

（我将其配置为

--enabled all

），没有任何错误。但当我想在elixir模式下运行它时，我会遇到以下错误：

# ejabberdctl iexlive
bad "K" value: \
Usage: beam.smp [flags] [ -- [init_args] ]
The flags are:

-sub bool      enable/disable scheduler utilization balancing,
               see the erl(1) documentation for more info.

-sss size      suggested stack size in kilo words for scheduler threads,
               valid range is [4-8192]
-spp Bool      set port parallelism scheduling hint
-S n1:n2       set number of schedulers (n1), and number of
               schedulers online (n2), maximum for both
               numbers is 1024
-SP p1:p2      specify schedulers (p1) and schedulers online (p2)
               as percentages of logical processors configured and logical
               processors available, respectively
-t size        set the maximum number of atoms the emulator can handle
               valid range is [8192-0]

-v             turn on chatty mode (GCs will be reported etc)
-W<i|w|e>      set error logger warnings mapping,
               see error_logger documentation for details
-zdbbl size    set the distribution buffer busy limit in kilobytes
               valid range is [1-2097151]
-zdntgc time   set delayed node table gc in seconds
               valid values are infinity or intergers in the range [0-100000000]

Note that if the emulator is started with erlexec (typically
from the erl script), these flags should be specified with +.

我把它改成

ERLANG_OPTS=""

---

它成功了。但我不知道这是否会造成进一步的问题。我将在他们的存储库中打开一个问题。

这是因为

+K$POLL

中的

$POLL

变量未正确初始化。

+K

标志启用或禁用Erlang VM的内核轮询功能，其可接受值为

true

或

false

ejabberdctl

shell脚本为

$POLL

和其他Erlang VM选项提供了一些默认值。它还使用

ejabberdctl.cfg

config文件，并使用此配置文件中包含的值覆盖默认值

您应该使用

ejabberdctl.cfg

设置所需选项，并按如下方式取消注释：

#' POLL: Kernel polling ([true|false])
#
# The kernel polling option requires support in the kernel.
# Additionally, you need to enable this feature while compiling Erlang.
#
# Default: true
#
POLL=true

#.
#' SMP: SMP support ([enable|auto|disable])
#
# Explanation in Erlang/OTP documentation:
# enable: starts the Erlang runtime system with SMP support enabled.
#   This may fail if no runtime system with SMP support is available.
# auto: starts the Erlang runtime system with SMP support enabled if it
#   is available and more than one logical processor are detected.
# disable: starts a runtime system without SMP support.
#
# Default: enable
#
SMP=enable

---

如果您手动安装ejabberd，则此文件位于

$ejabberd安装路径/conf

上。

哑巴问题。在命令行上传递“K”参数时会发生什么？也许您还需要指定所有相关软件的名称/版本：例如，我正在Elixir 1.1上运行此软件。1@OnorioCatenacci我更新了我的问题。我想你需要弄清楚这些环境变量应该是什么（看看下面的答案）而不仅仅是删除它们。这不也需要设置其他环境变量吗？ERL_进程和ERL_选项环境变量？@OnorioCatenacci Yes

ERL_进程

和

ERL_选项

以及一些其他选项在

ejabberdctl.cfg

配置文件中提供。@HamidrezaSoleimani感谢我尝试了这个解决方案，但不幸的是它对我不起作用。
