I think the issue is that the previous CSV.jl release probably has a dependency version like “Parsers \>= 0.2” or something, and then when Parsers.jl made a breaking release to `0.3.0`, it breaks CSV.jl. I think if you do something like `] pin Parsers 0.2.22`, it should fix it for now.

Indeed, `] pin Parsers@0.2.22` worked for me (I also had to remove `JSON2` which insisted on `Parser@0.3` and then `] up`)

You could also do `] pin JSON2@0.2.4` if you still need JSON2. Hopefully we can get all these dependency issues figured out soon to avoid these situations.
