when I run this in terminal:
当我在终端运行时:
lsof -n -i4TCP:8081
lsof - n -i4TCP:8081
I get this
我得到这个
node 10901 me 28u IPv6 0xbcad49 0t0 TCP *:sunproxyadmin (LISTEN)
foo 11957 me 15u IPv4 0xbcad49 0t0 TCP 127.0.0.1:61127->127.0.0.1:sunproxyadmin (CLOSE_WAIT)
What is this sunproxyadmin?

Per http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=8081, TCP port 8081 is the well known port for sunproxyadmin the same way 80 is the well known port for http. In this case, you have a node process that is listening on port 8081, but lsof is trying to be helpful and show the well known port for this. Under linux, this is defined in /etc/services; I would expect OS X is similar.
每http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?搜索=8081,TCP端口8081是众所周知的sunproxyadmin端口，同样的方式80是众所周知的http端口。在本例中，您有一个在端口8081上监听的节点进程，但是lsof正在尝试提供帮助，并显示这个众所周知的端口。在linux下，这是在/etc/services中定义的;我希望OS X是类似的。

inhibits the conversion of port numbers to port names for network files.
Inhibiting the conversion may make lsof run a little faster. It is also useful when port name lookup is not working properly.禁止将端口号转换为网络文件的端口名称。抑制转换可能会使lsof运行得更快一些。当端口名称查找不能正常工作时，它也很有用。
This should cause lsof to not print out the confusing sunproxyadmin for something that just happens to use the port that Sun registered.
这将导致lsof不能打印出令人困惑的sunproxyadmin，因为它恰好使用了Sun注册的端口。
Edit 2: The second column in your response (e.g. 10901 in the first row, which is the one you want, and 11957 in the second row) should be the process ID. If you do ps aux | grep 10901 (or ps elf | grep [pid], as I can't remember which works right for OSX and don't have it handy) you should get something like:

You can kill it with kill -9 10901 (or whatever the PID was) though you might find it comes back if it's running as a service or what.
你可以用kill -9 10901(或者其他的PID)来杀死它，不过你可能会发现如果它是作为一个服务运行或者是什么，它会回来。
This is useful enough to add to your bash profile:
这很有用，可以添加到您的bash配置文件中:
function findbyport()
{
sudo lsof -P -iTCP:$1 -sTCP:LISTEN
}

Kill it, do in your terminal
杀了它，在你的终端。
sudo lsof -i :8081
from there get the PID number and then run
从那里得到PID号然后运行。
kill -9 <PID NUMBER>

If you don't want to kill sunproxyadmin process, let try to start React native in different port with command: react-native start --port your_port
如果您不想杀死sunproxyadmin过程，那么让尝试在不同的端口上使用命令来响应本地的本地操作:从本地开始——端口your_port。
Then open Dev settings (see how to open dev menu), and modify Debug server host & port for device to: your_local_ip:your_port
然后打开Dev设置(查看如何打开Dev菜单)，并将调试服务器主机和端口修改为:your_local_ip:your_port。
