ezgmail.init() error - Cannot access token.json: No such file or directory

[piyapawar]

Hello,

Following is the code which I am running in Colab. I have downloaded the credentials.json file as well. The ezgmail.init() doesnt open the gmail window. Can you please help.

CODE import ezgmail, os os.chdir(r'/content/sample_data') ezgmail.init()

ERROR /usr/local/lib/python3.6/dist-packages/oauth2client/_helpers.py:255: UserWarning: Cannot access token.json: No such file or directory.

If you create a token using the gmail api quickstart app then try to run it, you get a slightly different error which may be of use

`import os, ezgmail

os.chdir(r'/Users/ellieleep/Documents/GitHub/automatetheboringwithpython/Chapter 18')

ezgmail.init()

I had this same KeyError: '_module' error. I had run the Google gmail api quickstart (https://developers.google.com/gmail/api/quickstart/python) prior to discovering and installing ezgmail.

@ellieleep 's comment above + the docs mentioning that a token.json file is created, made me try deleting the token.json file that had been created after running quickstart.py. After that, I reran:

import ezgmail
ezgmail.init()

And everything worked.

Hope this helps someone.

So... I just went through this rigamarole as well with Google Cloud Platform - create a project, get API, build credentials, etc., etc. In the end, I was able to generate the credentials.json file and the subsequent token.json.

However, now I am getting a KeyError: '_module' error when calling ezgmail.init(). I have the prerequisite modules and files already. All solutions say to delete the token.json file and rerun the authorization process, but this does not work - at least for me.

Here is the traceback:

  File "<stdin>", line 1, in <module>
  File "c:\Installs\Python\lib\site-packages\ezgmail\__init__.py", line 471, in init
     creds = store.get()
  File "c:\Installs\Python\lib\site-packages\oauth2client\client.py", line 407, in get
     return self.locked_get()
  File "c:\Installs\Python\lib\site-packages\oauth2client\file.py", line 54, in locked_get
     credentials = client.Credentials.new_from_json(content)
  File "c:\Installs\Python\lib\site-packages\oauth2client\client.py", line 302, in new_from_json
     module_name = data['_module']
KeyError: '_module'

*** UPDATE ***

I changed a line in the ezgmail/init.py file (line 471) from:

  creds = store.get()

to:

 creds = None

and saved the file. Immediately upon running

 import ezgmail

apparently a new token.json file is written. I then reverted the ezgmail/init.py file (line 471) back to...

 creds = store.get()

... and now I can run ezgmail.init() with no issues!

This represents my limited knowledge of python and I am only just beginning, so please bear with my explanation above.
