[FIXED] python gTTS RuntimeError: Unable to get language list: 'NoneType' object is not subscriptable

Issue

Pre I have seen questions about this kind of error , but it was not related with gTTS.

I use gTTS module.One day,this error suddenly happened.Yes,I have never handled these codes from the time of importing it.Until yesterday,this error didn't happen.

It happened when I excute this code:

Code

sounditems = [i for i in gtts.lang.tts_langs().values()]

Error

RuntimeError: Unable to get language list: 'NoneType' object is not subscriptable

In [1]: import gtts

In [2]: gtts.lang
Out[2]: <module 'gtts.lang' from 'C:\\Anaconda3\\lib\\site-packages\\gtts\\lang.py'>

In [3]: gtts.lang.tts_langs()
Traceback (most recent call last):

  File "<ipython-input-3-53b538afe087>", line 1, in <module>
    gtts.lang.tts_langs()

  File "C:\Anaconda3\lib\site-packages\gtts\lang.py", line 41, in tts_langs
    raise RuntimeError("Unable to get language list: %s" % str(e))

RuntimeError: Unable to get language list: 'NoneType' object is not subscriptable

gTTS version

language

python 3.6.5

After search

I investigated in gTTS lang module.I thought it failes to get imformation from Google.Perhaps,it may not be the problem on the client side.

Added

After researching the lang.py module,I found out the source of error was from its _fetch_langs() function & it seems to have failed to execute soup.find(src=re.compile(JS_FILE))['src'].

Solution

gTTS 2.0.3 is already released.

I reinstalled gTTS module by following John D. and I updated lang.py.

I rewrote my original code from

gtts.lang.tts_langs()

to

gtts.tts.tts_langs()

I could solve the problem.

This is not the mirrored answer for my question,but I'm very satisfied. It seems that gtts module can be updated in the future and is under development now. I have no reason for persisting to gTTS 2.0.1
