anaconda navigator suddenly stops working

问题

Suddenly, my anaconda-navigator stops working! I tried to update it by typing in the terminal:

conda update conda
conda update anaconda-navigator 
anaconda-navigator

but nothing happened.

Then, I tried to install the following packages:

pip install chardet

and

conda install launcher 

I also tried to delete the following files:

rm -rf config.yaml

and

rm -Rf ~/.continuum ~/.anaconda

But nothing happened!

I still get the following error:

 Traceback (most recent call last):

    sys.modules['pip._vendor.requests.packages.' + mod] = sys.modules["pip._vendor." + mod]
KeyError: 'pip._vendor.chardet.constants'

What does this error mean? and what should I do to solve the problem?

Thanks in advance.

回答1:

I have solved this problem. To whomever is facing the same problem, after following the steps that I mentioned earlier in my question above, try to install the package:

pip install picage

since, as far as I understand, the error key that I get "pip._vendor.chardet.constants" is a subpackage from the main package (picage).

and then you can update your pip by typing (note that this step alone might solve the problem):

pip install --upgrade pip

At this point you can call your conda by typing:

anaconda-navigator

and hopefully it will open (it worked with me!).
