Please take a look at the versions in the screenshot you posted above. It's not that you don't have those packages, it's that you have the wrong versions of them.

So please correct that by installing the right versions.

Thanks for the tip. The task was not necessarily trivial though. I had to downgrade first parso and then jedi (in that order). Then I had to create a pinned file (as described in the documentation) and freeze the packages:

parso ==0.5.2
jedi ==0.15.2  

Finally, I had to install spyder. Let this serve others with the same problem.

[ccordoba12]

Yeah, that's not simple matter if you constantly run conda update --all. But if you avoid that (which I think you should) and only update the packages you need, then things will be much simpler.

im facing problem in spyder and anaconda both. nothing is installing and any component is not worling in my anaconda . please help

[ccordoba12]

Hey @mahimakaushik-oss, you need to remove the following directory to fix your problem:

C:\Users\Mahima Kaushik\AppData\Roaming\Python

[mahimakaushik-oss]

thanks a lot. your suggestion solved my problem. a big thanks for you :). i tried it for 5 hrs but failed but your suggestion solved my problem. thank you again

[mahimakaushik-oss]

@ccordoba12 but still my anaconda is not installing others files like dash , plotly . its showing something like " multiple error encountered". what to do for that?

[ccordoba12]

I'd recommend you to remove and reinstall Anaconda. Please see the second part of our video for that.
