Erlang Can'；t连接到特定的网络接口

我已经阅读了'inet'，'gen_tcp'的文档，但不明白错误在哪里

连接选项（） {ip，inet:socket_address（）}

套接字地址（）= ip_地址（）

ip_地址（）=ip4_地址（）| ip6_地址（）

ip6_地址（）= {0..65535, 0..65535, 0..65535, 0..65535, 0..65535, 0..65535, 0..65535, 0..65535}

所以它一定是{ip，{0..65535， 0..65535, 0..65535, 0..65535, 0..65535, 0..65535, 0..65535, 0..65535}

       {addr,{172,17,0,218}},
       {netmask,{255,255,255,128}},
       {broadaddr,{172,17,0,255}},
       {addr,{65152,0,0,0,20564,255,65253,1468}},
       {netmask,{65535,65535,65535,65535,0,0,0,0}}]},
     {"eth1",
      [{flags,[up,broadcast,running,multicast]},
       {hwaddr,[82,84,0,229,5,189]},
       {addr,{65152,0,0,0,51840,11332,54567,49336}},
       {netmask,{65535,65535,65535,65535,0,0,0,0}}]}]}

或

{error，einval}

如果再次检查文档，您将看到在使用ipv6地址时，您需要添加套接字选项inet6，您的代码中缺少该选项

请尝试此代码，它应该可以工作：

Op = [binary, {packet,line}, {active,false}, {reuseaddr,true}, inet6, {ip, {0,0,0,0,0,0,0,1}}].
gen_tcp:listen(8000, Op).

---

好的，但这仍然给出了一个错误Op=[binary，{packet，line}，{active，false}，{reuseaddr，true}，inet6，{ip，{65152,0,0,05184011335456749336}]。{好的，L}=gen_tcp:听（6653，Op）。**异常错误：右侧值{error，einval}f（Op）不匹配？您试图将一个变量分配给不同的值，如：a=1。A=2。这就是获得右侧值错误的方法。

Op = [binary, {packet,line}, {active,false}, {reuseaddr,true}, inet6, {ip, {0,0,0,0,0,0,0,1}}].
gen_tcp:listen(8000, Op).
