install: "Cask 'dvc' is not installed." error

[jorgeorpinel]

Installed DVC 0.64.0 via pkg on MacOS:

$ dvc version
DVC version: 0.64.0
Python version: 3.6.5
Platform: Darwin-19.0.0-x86_64-i386-64bit
Binary: True
Cache: reflink - True, hardlink - True, symlink - True
Filesystem type (cache directory): ('apfs', '/dev/disk1s5')
Filesystem type (workspace): ('apfs', '/dev/disk1s5')

Cloned and changed into the cloned iterative/example-get-started project, and ran dvc pull twice. Second run:

$ dvc pull
Error: Cask 'dvc' is not installed.

Everything is up to date.                                                                                                                                     

I realize this may be a fixed bug but just double checking it's not related to the updater.

@jorgeorpinel I think it happens here https://github.com/iterative/dvc/blob/0.66.1/dvc/updater.py#L176 since we are not silencing the output.

For the record, we can remove cask detection now, as we've abandoned it.

So one would need to delete https://github.com/iterative/dvc/blob/0.66.3/dvc/updater.py#L126 and this code block https://github.com/iterative/dvc/blob/0.66.3/dvc/updater.py#L173

I would like to work on it .

[efiop]

@kss682 Sure, go ahead! 🙂

[jorgeorpinel]

Thanks guys. So to summarize, the outputmentioned in #2680 (comment) should be silenced and Cask detection should be removed, as mentioned in #2680 (comment)). Right?
