issue under Julia v1.8.3

[StefanPofahl]

Here is my Julia Version:

Julia Version 1.8.3
Commit 0434deb161 (2022-11-14 20:14 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: 8 × Intel(R) Core(TM) i7-10510U CPU @ 1.80GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-13.0.1 (ORCJIT, skylake)
  Threads: 1 on 8 virtual cores

the package status is:

 pkg> st JLD2
Status `C:\Users\stefanpofahl\.julia\environments\v1.8\Project.toml`
⌃ [033835bb] JLD2 v0.4.3
Info Packages marked with ⌃ have new versions available and may be upgradable.

Now my short test:

using JLD2
a_vec = [1,2,3]
JLD2.jldsave("filename.jld", true; a_vec)

the response is:

ERROR: UndefVarError: jldsave not defined
Stacktrace:
 [1] getproperty(x::Module, f::Symbol)
   @ Base .\Base.jl:31
 [2] top-level scope
   @ REPL[4]:1

Hi @StefanPofahl, the latest release is v0.4.28 which means your version is from before jldsave was implemented. Please try to do a package update.

[StefanPofahl]

remove and add is not sufficient ...

[JonasIsensee]

In that case you probably have other packages installed or specific version requirements for dependencies of JLD2.

I recommend checking for FileIO.jl

[StefanPofahl]

(@v1.8) pkg> st FileIO

I have removed both packages and have re-installed JLD2:

there seems to be something quite wrong with julia installation.

I would recommend to rename your .julia folder (delete in the end but for now just rename) and start fresh.

[StefanPofahl]

After having removed the package via pkg> rm JLD2 I have removed the folders in: C:\Users\[...]\.julia\packages\JLD2 and specified the the version of package JLD2 in the following form:

Pkg.add(name="JLD2", version="0.4.28")

This worked as well. Really strange to me .... Thanks for your support!!!
