推荐答案

java 无法将 mynap3 解析为 localhost，因此您必须添加该行

java is unable to resolve mynap3 as localhost, so you'll have to add the line

127.0.0.1 localhost mynap3

到您的/etc/hosts 文件

to your /etc/hosts file

你可以通过执行来做到这一点

you can do this by executing

sudo bash
echo "127.0.0.1 localhost mynap3" >> /etc/hosts
