Rebar3 +牛仔内核PID终止
我安装rebar3
并且创造Rebar3 +牛仔内核PID终止
cd ~/apps rebar3 new release tunnel
然后
我复制我的src
文件从~/tunnel/src/*
到~/apps/tunnel/src/
一个新的版本我遇到了一个编译与rebar3 run
错误,并找到Erlang "Kernel pid terminated" error作为一种可能的解决方案。我将关于tunnel_app
的所有内容重命名为tunnel
。所以我的src
包含tunnel.erl
,tunnel.app.src
和tunnel_sup.erl
。我根据需要重新命名了模块定义。
这里的rebar3 run
错误:

这是为什么崩溃?
如果这是你与rebar3第一次的经验,我建议从一个OTP应用程序,而不是一个OTP版本:
rebar3 new app tunnel
,然后不要盲目在源文件,因为你可能在覆盖这些文件复制已在src
以下为您创建。事先查看该目录的内容。
我也建议花时间阅读rebar3 https://www.rebar3.org/docs/basic-usage页面。
您还必须阅读有关OTP应用程序的内容。我知道,相当多的理解,有时令人困惑。免费来源是http://learnyousomeerlang.com/building-applications-with-otp。购买关于Erlang的书也是值得的。有几个,我建议https://www.manning.com/books/erlang-and-otp-in-action。
还有一个在线课程,免费,启动几天(2017年2月20日)https://www.mooc-list.com/course/functional-programming-erlang-futurelearn
谢谢!我在https://gist.github.com/flbuddymooreiv/ce1d7a47b12c27bf1616。在LearnYouSomeErlang中,我是其中的几个章节,感谢您指出了这一点。我会看看课程和RTFM =) – quantumpotato
啊我看到'rebar3 release'使多个应用程序可用与应用程序只是一个src目录 – quantumpotato
你为什么要SRC文件复制从〜/隧道/ src目录/ *到〜/应用/隧道/ src目录/? – byaruhaf
@byaruhaf我在〜/ tunnel/src中已经有了我的项目src文件。 – quantumpotato
