ERROR: LoadError: LoadError: UndefVarError: tostr_sizehint not defined

[goedman]

Above error (last line in src/depreciations.jl) fails DataFrames on Julia 1.4-DEV. After some testing on Julia 1.3 I don't think Julia 1.3 needs it. I don't have Julia 1.0 to 1.2 installed, but wonder if it is still needed.

This is causing me headaches too, thanks for reporting

[goedman]

Thank you! I'll close this issue after the fix is merged.

Seem to have the same issue (maybe related: JuliaLang/julia#33953 and #229)

Funny, I didn't expect so many people to use Julia 1.4. :-)

I only use it for CI and noticed the issue because https://travis-ci.org/gaelforget/IndividualDisplacements.jl failed with nightly

Thanks for the fix (will rerun my pkg CI once 0.7.4 is registered)

Guys, I'm fairly new to Julia, what exactly is the fix? Is there something I can copy & paste? And would I run it in Terminal?
I'm not sure what happened. Julia was working just fine, but all of a sudden I can't run "using CSV" without this "tostr_sizehint not defined" error.

What is the version of Julia, CSV, DataFrames, and CategoricalArays you are using?
(use versioninfo() and using Pkg; Pkg.status() to get this information)

Thank you!

Thank you for your help!

I've tried removing and re-adding the CSV.jl package, updating the package, uninstalling and reinstalling Julia, not sure what else to try.

[bkamins]

You have CSV version 0.3.1 installed - it is grossly outdated and unsupported. The current version is 0.7.7.
Similarly DataFrames.jl - you have version 0.13.1 and has not been supported for several years now. The current version is 0.21.7. Similarly with ECharts.jl.

Install current version of DataFrames.jl by writing add [email protected] and tell me what error you get.

All right, I got it.
After trying
Pkg.add(Pkg.PackageSpec(name="DataFrames", version="0.21.0"))
there appeared to be an issue with ECharts, obviously being outdated, so I used

Pkg.add(Pkg.PackageSpec(name="ECharts", version="0.4.0"))
Pkg.add(Pkg.PackageSpec(name="DataFrames", version="0.21.0")),

but I STILL got some error with ECharts, so I had to remove it first:
Pkg.rm("ECharts"); recursive=true
And finally, DataFrames updated, and now so are the rest of my packages :)
Thank you very much!

If you like ECharts.jl you need to do add ECharts#master or ask its maintainer to make a release (the package has not seen a release for almost a year now).
