Hi, I am doing some work quite unrelated to the reading of CSV-files, however I am very much impacted by the issue described in csv-jl-fails-precompling #67195 . Since my preferred package (GeoArrays.jl, which has a dependancy to CSV.jl) worked earlier this summer, I tried reverting back to Julia 1…

Impossible to say without knowing more details but you can try it from the Julia REPL after starting Julia with julia --startup-file=no.

[image] CSV.jl fails precompling, TypeError: in Type{...} expression, expected UnionAll, got Type{Parsers.Options} This can usually be fixed by pinning Parsers.jl to v1.2.1 for the time being. A new CSV.jl release compatible with Parsers.jl 2.0 is coming soon, hopefully in the next week or so. …

Hi Sukera, Thanks for your speedy response. Unfortunatly the work-around in question doesn’t work for me, the problem persists even though I have the following in the manifest file: [[Parsers]] deps = [“Dates”] git-tree-sha1 = “bfd7d8c7fd87f04543810d9cbd3995972236ba1b” pinned = true uuid = “69…

I did. In a clean environment in directory .../testenv, in pkg mode: (@v1.7) pkg> activate . (testenv) pkg> add Parsers (testenv) pkg> pin Parsers@1.1.2 (testenv) pkg> add CSV@0.8.0 Reverting to REPL mode: using CSV [ Info: Precompiling CSV [336ed68f-0bac-5ca0-87d4-7b16caf5d00b] ERROR: LoadError:…

The versions mentioned in the linked post are Parser@v1.2.1 CSV@v0.8.5 whereas you have Parsers@1.1.2 and CSV@0.8.0. Can you try with the versions above instead?

For me this configuration works: (testenv) pkg> st Status `~/tmp/testenv/Project.toml` [336ed68f] CSV v0.8.5 [69de0a69] Parsers v1.1.2 julia> using CSV [ Info: Precompiling CSV [336ed68f-0bac-5ca0-87d4-7b16caf5d00b] and also with CSV@0.8.0 with Julia 1.6.1 (and on Ubuntu). The setting m…

Interesting. Maybe @quinnj knows more about why that particular combination doesn’t work?

There is no version 1.2.1 (I suspect that was a typo for 1.1.2), but @mike_k seems to have it working with an earlier version of Julia than I’m using. I guess I’ll just have to wait.

sorry for my impreciseness,… yes, there is no version 1.2.1 (this is what I have meant)

Thanks so much for your efforts, however neither the combination Parsers v1.1.2 + CSV v0.8.0 nor Parsers v1.1.2 + CSV v0.8.5 work for me. So I am also in waiting mode. In the mean time: Is some kind of time-capsule functionality (as hinted at in the original post) feasible? Or can we (and by th…

Reverting back to avoid precompile errors?

Did you try removing the CSV package and to re-add it to a specific version, e.g., as described here?
