在没有DNS的情况下导入validate_email失败

Question

我在termux中使用pip安装了validate_email。后来我尝试导入validate_email，但是似乎出现了错误。

from validate_email import validate_email
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/data/data/com.termux/files/usr/lib/python2.7/site-packages/validate_email.py", line 34, in <module>
    DNS.DiscoverNameServers()
  File "/data/data/com.termux/files/usr/lib/python2.7/site-packages/DNS/Base.py", line 78, in DiscoverNameServers
    return ParseResolvConf()
  File "/data/data/com.termux/files/usr/lib/python2.7/site-packages/DNS/Base.py", line 53, in ParseResolvConf
    lines=open(resolv_path).readlines()
IOError: [Errno 2] No such file or directory: '/etc/resolv.conf'
