When i type Pkg.add("IJulia")
it returns: SystemError: opening file "C:\Users\justi\.julia\registries\General\Registry.toml": No such file or directory

Thanks for contributing to the Julia project!

Can you try to delete C:\Users\justi\.julia\registries\General and try again?

[justintong97]

it works， thanks for solving my problem 获取 Outlook for iOS<https://aka.ms/o0ukef>

Perhaps we can detect this ourselves and re-download General if this is the case?

Can you try to delete C:\Users\justi\.julia\registries\General and try again?

when you say delete how do you mean facing the same issue over here when tried to add the general after removing it since DataFrames was having issues with versioning

I see this error too from time to time on Windows computers (last time on a Windows computer with julia 1.5.1 from a student). Removing C:\Users\<name>\.julia\registries\General always resolved the problem, but it would be nice to know the root cause of it. Unfortunately, this issue is very difficult to reproduce.

Here are other reports:
https://discourse.julialang.org/t/unable-to-install-ijulia/47160/2
JuliaLang/julia#37521

Is there any information that would be helpful to collect the next time this issue shows up? Maybe Linux and Mac handle better transient network issues when doing a git checkout than Windows?

[fredrikekre]

it would be nice to know the root cause of it.

Windows or some program on your computer deletes it.

[fredrikekre]

Here is another example where Windows deleted folders even: #2017 (comment), and here are a bunch more https://discourse.julialang.org/search?q=Registry.toml%22%3A%20No%20such%20file%20or%20directory

[StefanKarpinski]

It's absolutely bananas that Windows just deletes stuff, but that seems to be what happens.

[Alexander-Barth]

Yesterday, I had the first time seen this error (/Users/admin/.julia/registries/General/Registry.toml": No such file or directory while installing the first julia package; julia 1.5.1, I think) on a student's Mac. I thought that this problem was Windows specific.

I had a look at the code, and it is really strange:

• At line 1004 the file is there (as the error message is not printed),

  Pkg.jl/src/Types.jl

  Line 1004 in f1430b5

  if !isfile(joinpath(tmp, "Registry.toml"))

• At line 1007, Registry.toml is missing

  Pkg.jl/src/Types.jl

  Line 1007 in f1430b5

  registry = read_registry(joinpath(tmp, "Registry.toml"); cache=false) # don't cache this tmp registry

[fredrikekre]

The error is from a later stage after the registry has been copied to the correct place.

Hi, such things seem to happen also outside of Julia...

https://techcommunity.microsoft.com/t5/storage-at-microsoft/windows-10-and-storage-sense/ba-p/428270

There seems to be a thing like StorageSense which may be involved. Also some people report about
deactivating AV software like avast. No clear picture though.

Disclaimer: I am not a windows user, just do it occasionally in a VM - for the odd .docx and for testing Julia packges, so all of this was just googled.
