Question

Last night I ran a Windows update and this morning Anaconda Navigator hangs when I try to launch it. After googling I ran some updates in Anaconda prompt:

conda update
conda update anaconda-navigator

And then when I try to launch anaconda navigator from the prompt I get this error:

2019-03-01 09:23:00,212 - ERROR download_api._get_url:416
Expecting value: line 1 column 1 (char 0)

Traceback (most recent call last):
File "C:UsersxxxxAnaconda3libsite-packagesanaconda_navigatorwidgetsmain_window.py", line 539, in setup
self.post_setup(conda_data=conda_data)
File "C:UsersxxxxAnaconda3libsite-packagesanaconda_navigatorwidgetsmain_window.py", line 576, in post_setup

File "C:UsersxxxxAnaconda3libsite-packagesanaconda_navigatorapianaconda_api.py", line 888, in process_apps
versions=[vsdata.get( productVersion )],
AttributeError:  str  object has no attribute  get

I use Jupyter Notebook and Spyder and this is causing me a major headache. Thanks in advance!

Answer 1

There s another solution (not the best, but it works). Anaconda can t retrieve vscode version for any reason.

You need to replace line 888 in file "C:UsersxxxxAnaconda3libsite-packagesanaconda_navigatorapianaconda_api.py"

from versions=[vsdata.get( productVersion )], to versions=["1b8e8302e405050205e69b59abb3559592bb9e60"],

Answer 2

After lots of restarts and lots of googling I found a simple fix:

conda update navigator-updater

It works...for now

Answer 3

For me it worked only when I m connected to the internet. Offline, it fails to start.

Answer 4

As a ubuntu user it happened with me too, i used to remove anaconda-navigator and install it again through commands

-conda remove anaconda-navigator

-conda install anaconda-navigator

if it didn t work, check the troubleshooting page here https://docs.anaconda.com/free/navigator/troubleshooting/
