Anaconda Error - Module 'Brotli' Has No Attribute 'Error'

I solved this issue by commenting lines 376 & 377 in the file

C:\ProgramData\Anaconda3\Lib\site-packages\urllib3\response.py

and then install brotli library by running either

pip install brotli

or

conda install brotli

After successful installation, uncomment above lines. Do whatever you want now. Error should not come.

I solved the issue by installing urllib3

Just open the terminal and type:

conda install -c anaconda urllib3

or you can also try:

conda install -c conda-forge brotlipy

I solved the issue by installing brotlipy

Just open the terminal and type:

conda install -c anaconda brotlipy

the commands below works for me somehow:

pip install -U urllib3
pip install -U brotlipy

Yet another variation on a fix: for me (Windows 10, minconda3), installing brotli via pip fixed the problem.

Since I could not use any of these conda commands (list, update, install), the solution had to come from pip! Even though the error message pointed to urllib3, I first reinstalled brotli with pip, then performed my initial conda list command flawlessly... so I did not update or modify urllib3 in any way, which is kind of strange!

I solved this problem by the following way

1- comment the lines 
2- conda install brotli
3- run anaconda like normal 

i kept the lines 376 and 377 commented

I faced the same issue, but I was able to fix it by simply installing brotli.

conda install brotli

Brotli v1.0.7 fixed the problem for me.

I did the following:

1. commented out the recommended lines above.
2. launched the anaconda navigator
3. searched for any packages with "brotli"
4. installed / updated all of those
5. uncommented out the lines

Navigator is back working but not sure of any other downstream issues yet.

I solved this issue by commenting lines 389 & 390 in the file

C:\Users\(user)\AppData\Roaming\Python\Python36\site-packages\urllib3\response.py

and then install brotli library by running

pip install brotli
