ImportError: No module named dns.exception

Question

I am trying to use the dnspython in my code but when it gets to the import statement, I get the following error:

>>> import DNS.resolver
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\python27\lib\site-packages\DNS\resolver.py", line 31, in <module>
    import dns.exception
ImportError: No module named dns.exception

I have tried installing with pip, easy_install and manually from the git repo but nothing seems to do the trick. Any ideas??

Code:

import DNS.resolver

if __name__ == "__main__":

    domain = 'hotmail.com'
    for x in dns.resolver.query(domain, 'MX'):
        print x.to_text()

`Import DNS` works but then I get, `NameError Occured name "dns" is not defined` at this line `dns.resolver.query(domain, 'MX')` — TomSelleck, Sep 04 '14 at 13:31
Ah hah! `import DNS` is for another module called [pydns](http://pydns.sourceforge.net/) — TomSelleck, Sep 04 '14 at 13:34

Another thing you can do to fix problems with this package is to install python-dnspython again using Synaptic. (Whether no having previous problems about duplicity)

Sometimes if you try to install this package using pip could appear some problems like that:

Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/dnspython Storing debug log for failure in /root/.pip/pip.log

Using Synaptic cleans the old files and install the new ones, from that package. I know this issue is solved but I wanted to add more information about this :)

Until I saw your answer I was trying `pip install dns`. Thanks for the heads up that the package is actually called **dnspython**. – jeteon Jan 21 '17 at 18:21

Yes, but run `pip install dnspython` – George Ogden Apr 07 '21 at 20:10

That's because package and module names are lowercase (see PEP 8). This works just fine :

import dns.resolver
import dns.exception

You should also be careful that none of your own *.py filename conflicts with the dns package. Your *.py file should not be named dns.py. Pay also attention to the *.pyc files.

How did you name your *.py file ? – Mathieu Schopfer Sep 04 '14 at 13:27
Hmm the name is completely different and the error happens in the interpreter as well – TomSelleck Sep 04 '14 at 13:29
That is weird. Your piece of code works just fine. Check in all directories in your python path that no custom module is conflicting. – Mathieu Schopfer Sep 04 '14 at 13:33

You're correct! It was conflicting with another module I had installed, [PyDNS](http://pydns.sourceforge.net/) – TomSelleck Sep 04 '14 at 13:42
thanks for your answer ...actually my issue was my file name. so, guys don't name your file with any conflict names like dns.py or like that – Amit Tiwari Nov 08 '21 at 15:22

First, your code should be : import dns.resolver.

There seems to be an issue installing dnspython using pip, you should clone the dnspython repository using git and run the file setup.py as follows:

git clone https://github.com/rthalley/dnspython
cd dnspython\
python setup.py install

If you don't have git installed on your machine, you can just download the repository manually .
