ImportError: No module named dns.resolver

[bfosterscripps]

On macOS Catalina (v10.15.5).
I cloned the repository, ran sudo pip install -r requirements.txt, and when I try to use the script, I get this error:

$ python sublist3r.py −d example.com
Traceback (most recent call last):
  File "sublist3r.py", line 21, in <module>
    from subbrute import subbrute
  File "/Users/bfoster/tools/Sublist3r/subbrute/subbrute.py", line 18, in <module>
    import dns.resolver
ImportError: No module named dns.resolver

I have already followed suggestions elsewhere online (including a similar problem with issue #223):

• https://github.com/ArchiveTeam/grab-site/issues/95#issuecomment-252634576
• https://stackoverflow.com/a/39413922/14197634
• https://github.com/aboul3la/Sublist3r/issues/223#issuecomment-593933233

The solution in these links is:

pip3 install dnspython==1.15.0 # or
pip install dnspython==1.15.0 # or
pip install dnspython 

When I run these I get:

$ pip install dnspython==1.15.0
Requirement already satisfied: dnspython==1.15.0 in /usr/local/lib/python3.8/site-packages (1.15.0)

When I re-try the pip install -r requirements.txt I get:

$ sudo pip install -r requirements.txt

Requirement already satisfied: chardet<4,>=3.0.2 in /usr/local/lib/python3.8/site-packages (from requests->-r requirements.txt (line 3)) (3.0.4)

Yet I still get:

$ python sublist3r.py −d example.com
Traceback (most recent call last):
  File "sublist3r.py", line 21, in <module>
    from subbrute import subbrute
  File "/Users/bfoster/tools/Sublist3r/subbrute/subbrute.py", line 18, in <module>
    import dns.resolver
ImportError: No module named dns.resolver

EDIT: I found a "workaround" - apparently when you use python3 it works:

$ python3 sublist3r.py -d example.com

This is most likely not a workaround, rather you calling python2 to run the script. What is the output of python --version?

[bfosterscripps]

I meant workaround in the sense that I was able to use python3, even if python2 wasn't working.

As requested:

$ python --version
Python 2.7.16

[testusername911]

Having this issue as well. I also noticed when you used python3, bruteforcing does not proceed.

[PrajwalKhante]

use python3

Thanks for the solution.

Try to git clone https://github.com/rthalley/dnspython on the /Sublist3r and cd /dnspython sudo python3 setup.py install

It's work maybe

For anyone looking for a quick fix, just edit the shebang at the top of sublist3r.py :

#!/usr/bin/env python3 #instead of python

[fherdlcruz]

My solutions:

I was installed the next library py3dns. I just removed the library py3dns and install pip install dnspython and ready!

Thanks!
