问题描述

我安装了 rebar3 并创建了一个新版本，其中




cd〜/ apps
rebar3 new release tunnel



然后



我将 src 文件从〜/ tunnel / src / * 复制到 〜/ apps / tunnel / src /



我遇到一个编译错误， rebar3 run 并发现 ErlangKernel pid terminated错误作为可能的解决方案。我将所有关于 tunnel_app 的内容重命名为 tunnel 。所以我的 src 包含 tunnel.erl ， tunnel.app.src 和 tunnel_sup.erl 。我重新命名模块定义。



这是$ code> rebar3运行错误：

正在写崩溃转储

为什么这是崩溃？

解决方案

如果这是您第一次使用rebar3的经验，使用OTP应用程序，而不是OTP版本：

  rebar3新应用程序隧道
  / pre> 
 
 
，然后不要盲目地复制源文件，因为您有风险覆盖在 src 之下为您创建的文件。请先查看该目录的内容。
 
 
 
我还建议花时间阅读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，相当多的理解和有时混乱。免费来源是 http://learnyousomeerlang.com/building-applications-with-otp。买一本关于Erlang的书也是值得的。有几个，我建议 https://www.manning.com / books / erlang-and-otp-in-action 。

I installed rebar3 and created a new release with




cd ~/apps
rebar3 new release tunnel




Then



I copied my src files from ~/tunnel/src/* to ~/apps/tunnel/src/



I ran into a compile error with rebar3 run and found Erlang "Kernel pid terminated" error as a possible solution. I renamed everything about tunnel_app to tunnel. So my src contains tunnel.erl , tunnel.app.src and tunnel_sup.erl. I renamed the module definition as appropriate.



Here's the rebar3 run error:

Crash dump is being written

Why is this crashing?
 解决方案 
If this is your first experience with rebar3, I suggest starting with an OTP application, not an OTP release:
rebar3 new app tunnel

and then do not blindly copy over the source files because you risk overwriting the files that have been created for you below src. Have a look at the contents of that directory beforehand.



I also suggest to take the time to read the rebar3 https://www.rebar3.org/docs/basic-usage page.



You will also have to read about what an OTP application is. I know, quite a lot to understand and sometimes confusing. A free source is http://learnyousomeerlang.com/building-applications-with-otp. It is also worthwhile to buy a book about Erlang. There are a few, I suggest https://www.manning.com/books/erlang-and-otp-in-action.



There is also an online course, free, that starts in a few days (20th Feb 2017) https://www.mooc-list.com/course/functional-programming-erlang-futurelearn
