我的主目录（Ubuntu）中有以下.erlang文件：
io:format("executing user profile in home/user/.erlang\n",[]).
code:add_pathz("/media/user/Disk2/Cloud/Workspace/Erlang").
code:add_pathz("/media/user/Disk2/Cloud/Workspace/Erlang/code").
shell_default:cd("/media/user/Disk2/Cloud/Workspace/Erlang").
io:format(".erlang rc finished\n",[]).
我可以看到当我在终端中启动Erlang shell时运行该文件。更重要的是，shell_default：cd-command工作正常。但是，代码：add_pathz-commands没有。当我尝试在代码目录中运行任何东西时，我得到一个“未定义的函数” - 错误。此外，当我用“code：get_path（）。”列出路径时，我得到：

为什么“code：add_pathz”不起作用？感谢。

上面的路径有效。错误是代码目录中的.beam文件。重新编译使它们可以从＆＃34;代码＆＃34; -directory外部访问。
