How to install pytube3 in Anaconda?

In a quest to install pytube3 in Anaconda, searched for that package but couldn't find it

Then, went to Anaconda Prompt and ran

conda install pytube3

None of this worked...

The easiest is to open Spyder and run the following in your kernel

pip install pytube3

Then, Restart kernel and you'll be able to use it just fine.

Now, if you run

pip show pytube3

you'll see something like this

If then you try to download a file and get an error

  File "C:\Users\tiago\Anaconda3\lib\site-packages\pytube\extract.py", line 301, in <listcomp>
    parse_qs(formats[i]["cipher"]) for i, data in enumerate(formats)

KeyError: 'cipher'

then this answer will help you.
