googletrans Encounters 'NoneType' Error: Troubleshooting and Solutions

The googletrans library has experienced issues with a 'NoneType' error, attributed to potential IP bans or changes at Google's end. This article examines the problem and offers solutions to resolve it.

Problem Analysis

Upon attempting to use the googletrans library for language translation, users encountered an error:

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    translator.translate('안녕하세요.')
  ...
AttributeError: 'NoneType' object has no attribute 'group'

This error suggests that the library is unable to connect to the translation service and retrieve the necessary data.

Solution 1: Install Updated Version with Fix

Google has released an updated alpha version of googletrans (3.1.0a0) that includes a fix for the 'NoneType' error. To install the update, use the following command:

pip install googletrans==3.1.0a0

Solution 2: Specify Service URL

If the update does not resolve the issue, try specifying the service URL explicitly:

from googletrans import Translator
translator = Translator(service_urls=['translate.googleapis.com'])
translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')

Solution 3: Googletrans Alternative

If the above solutions fail, consider using an alternative library, such as google_trans_new. This library has reportedly worked for some users who experienced the 'NoneType' error with googletrans. To install and use it:

pip install google_trans_new

from google_trans_new import google_translator  
translator = google_translator()  
translate_text = translator.translate('สวัสดีจีน',lang_tgt='en')
