Erlang（钢筋？）：固定“潜在地包括在两个不同的应用”错误 [英] Erlang (rebar?): fixing "potentially included by two different application" errors

问题描述

所以我需要从git快照中构建 riak （注意：还有最近的官方快照共享相同的问题）。

So I need to build riak from git snapshot, (note: there's also a recent official snapshot sharing same problem).

在构建期间，发生以下情况：

During build, following happens:

Generating dev1 - node='dev1@127.0.0.1' yzsolrjmx=10013 yzsolr=10014 pbc=10017 http=10018 handoff=10019
(cd rel && ../rebar generate target_dir=../dev/dev1 overlay_vars=vars/dev1_vars.config)
==> rel (generate)
ERROR: generate failed while processing /tmp/riak/rel: {'EXIT',{{badmatch,{error,"Module mochijson2 potentially included by two different applications: mochiweb and rabbit."}},

它看起来像一个经典的从哪里继承的问题，我不认为不包括任何一个模块完全不会分发将有所帮助（尽管如果这样 - 如果它保留RMQ，我将要消除兔子支持）。

It looks like a classic "from where to inherit" problem, and I don't think that excluding either module completely from distribution will help (although, if it does - I'm going to expunge rabbit support if it stays for RMQ).

然而，更奇怪的是：对于兔子， grep 显示没有源树点，可以将其删除。 WTF？

However, it's even more strange: grep for rabbit shows no source tree points, where it can nbe removed. WTF?

推荐答案

当reltool发现两个应用程序共享相同的模块时，这是一个常见问题。

This is a common problem when reltool finds two applications share the same module.

你有兔子在/ tmp / rabbit周围，还是安装在ERL_LIBS？

Do you have rabbit somewhere around /tmp/rabbit or maybe it's installed in ERL_LIBS?
