安装氮气时出错

Question

我想去探索氮。按照http://nitrogenproject.com/doc/tutorial.html中概述的安装说明，我从GitHub中提取源代码，执行第二步，生成rel_inets，并撞墙。这是系统告诉我的：

nitrogen$ make rel_inets
...
make[2]: Leaving directory `/home/lloyd/Erl/nitrogen'
Running Erlang
Generating "reltool.config" with merged overlays
...Loading base file: "reltool_base.config"
...Merging Overlay from "reltool_inets.config"
...Writing "reltool.config"
...SUCCESS
make[2]: Entering directory `/home/lloyd/Erl/nitrogen'
Running Erlang
==> rel (generate)
ERROR: generate failed while processing /home/lloyd/Erl/nitrogen/rel: {'EXIT',      {{badmatch,{error,"Illegal library \"/home/lloyd/Programming/Erlang/zippity/apps\": no such file or directory"}},

原来，/home/lloyd/Programming/Erlang/zippity/app很久以前就被删除了；例如，它不在我的目录树中。

任何善良的巫师都能告诉我为什么世界上会挖出这段古老的历史吗？还有..。我能做些什么？

非常感谢，

根据要求，我编辑了Makefile的第231行。下面是make rel_inets的输出：

非常感谢伙计们。显然，我在某个时候设置了ERL_LIBS，但没有完全理解它的含义。当我删除库目录时，ERL_LIBS值是孤立的。所以，unset ERL_LIBS做到了这一点。现在装上了氮气。

重新安装Erlang :感谢Bob的提示，我从系统中清除Erlang，安装Erlang依赖项，然后通过kerl重新安装Erlang。钢筋现在编译。在多次警告之后，n2o仍然没有合作--在编译过程中停止。但我今天就去做。

再次感谢，
