Hello All,

I am running **Julia 1.7.1** on **MacOS Monterey 12.1** , I to use CSV by running the command `using CSV` and I got this:

Probably just an old version, what’s the output of `] st` in the environment you’re trying this in?

This should be solved, see Issue [#965](https://github.com/JuliaData/CSV.jl/issues/965). Try `] add CSV@v0.10.2` to get the latest version.

Hi,

I have the same issue with Julia 1.6 on Windows 10 but neither updating nor installing the latest version `CSV v0.10.2` fixes the issue. I have `Parsers v2.2.2`.

This doesn’t look like the same issue though, does it? The error message doesn’t mention parsers at all.

Are you running this in a fresh Julia session in the REPL? Can you show the output of `]st` and `versioninfo()`?

Ah, `Parsers` was mentioned in [here](https://github.com/JuliaData/CSV.jl/issues/965) as a possible solution.

Again that issue is about errors which explicitly show Parsers erroring during precompilation, which your error did not. Your issue was likely unrelated, but glad to see it worked out now.

Just to be sure I just tried a fresh install of CSV 0.10.2 on both Julia 1.7.2 and 1.6.5 (Windows 10), both worked flawlessly, installing Parsers 2.2.2 as a dependency.

As an aside, there isn’t really any reason to use Julia 1.6.2, the current release is 1.7.2.

The same issue, Julia 1.7.1 - Win10 as running Julia in the Atom’s REPL (also with package updates and restarts). However `using CSV` from a command line REPL solved the problem, and CSV now available in Atom too.

I have the same issue with Windows 10, Julia 1.72 and VSCode. Opening a command line REPL and running `using CSV` solves the problem. It’s happened twice so far, yesterday and today, after running `]update` in VSCode.

Same thing here on Windows 10 and Julia 1.72, as well as for my colleague that was on Julia 1.6.1 and Win10.

In our case multiple `using CSV` (like 5 times) until worked fixed the problem. That is rather odd

I can add my own experience with this issue (same output as reported by @Eben60) - I eventually got the precompile to work, but only after trying to precompile ~6 times in an external PowerShell, then opening a new PowerShell inside VS Code and doing precompile again.

I’m using Windows 10 and current Julia, CSV versions
