我使用twilio gem而且我不知道如何发布电话号码.我尝试:

@client.account.incoming_phone_numbers.delete(:phone_number => phone_number)

但铁路说:

undefined method `delete' for #<Twilio::REST::IncomingPhoneNumbers:0x7f35c99e93e0>

如何纠正发行号码？

我正在运行Amazon Linux AMI和nginx,当我尝试启动我的nginx服务器时:

$ sudo /etc/init.d/nginx restart

我收到以下错误:

nginx: [emerg]: bind() to IP failed (99: Cannot assign requested address)

其中"IP"是我的IP地址的占位符.有人知道为什么会发生错误吗？这是在EC2上运行的.

我的nginx.conf文件如下所示:

user              app;
worker_processes  4;

#error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
