Fix Python – googletrans stopped working with error ‘NoneType’ object has no attribute ‘group’

Question

Asked By – steveJ

I was trying googletrans and it was working quite well. Since this morning I started getting below error. I went through multiple posts from stackoverflow and other sites and found probably my ip is banned to use the service for sometime. I tried using multiple service provider internet that has different ip and stil facing the same issue ? I also tried to use googletrans on different laptops , still same issue ..Is googletrans package broken or something google did at their end ?

>>> from googletrans import Translator
>>> translator = Translator()
>>> translator.translate('안녕하세요.')

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    translator.translate('안녕하세요.')
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/client.py", line 172, in translate
    data = self._translate(text, dest, src)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/client.py", line 75, in _translate
    token = self.token_acquirer.do(text)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/gtoken.py", line 180, in do
    self._update()
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/gtoken.py", line 59, in _update
    code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
AttributeError: 'NoneType' object has no attribute 'group'

Now we will see solution for issue: googletrans stopped working with error ‘NoneType’ object has no attribute ‘group’


Answer

Update 01/12/2020: This issue re-emerged lately, (apparently) caused once again by some changes on the Google translation API.

A solution is being discussed (again) in this Github issue. Although there is not a definitive solution yet a Pull Request seem to be solving the problem: https://github.com/ssut/py-googletrans/pull/237.

While we wait for it to be approved it can be installed like this:

$ pip uninstall googletrans
$ git clone https://github.com/alainrouillon/py-googletrans.git
$ cd ./py-googletrans
$ git checkout origin/feature/enhance-use-of-direct-api
$ python setup.py install

Original Answer:

Apparently it’s a recent and widespread problem on Google’s side.
Quoting various Github discussions, it happens when Google sends you directly the raw token.

It’s being discussed right now and there is already a pull request to fix it, so it should be resolved in the next few days.

For reference, see:

https://github.com/ssut/py-googletrans/issues/48 <– exact same problem reported on the Github repo
https://github.com/pndurette/gTTS/issues/60 <– seemingly same problem on a text-to-speech library
https://github.com/ssut/py-googletrans/pull/78 <– pull request to fix the issue

To apply this patch (without waiting for the pull request to be accepted) simply install the library from the forked repo https://github.com/BoseCorp/py-googletrans.git (uninstall the official library first):

$ pip uninstall googletrans
$ git clone https://github.com/BoseCorp/py-googletrans.git
$ cd ./py-googletrans
$ python setup.py install

You can clone it anywhere on your system and install it globally or while inside a virtualenv.
