‘’‘julia  
using BenchmarkTools  
@benchmark sort(data) setup=(data=rand(10))

When I ran these code in Vs-code, errors as below:  
BenchmarkTools.Trial: 10000 samples with 1000 evaluations.  
ERROR: MethodError: no method matching median(::Vector{Float64})

Closest candidates are:  
median(::AbstractVector{T} where T\<:Real, ::AbstractWeights)  
@ StatsBase C:\Users\zzzz.julia\packages\StatsBase\XgjIN\src\weights.jl:782  
median(::BenchmarkTools.Trial)  
@ BenchmarkTools C:\Users\zzzz.julia\packages\BenchmarkTools\QAv7m\src\trials.jl:129  
median(::Distributions.Kolmogorov)  
@ Distributions C:\Users\zzzz.julia\packages\Distributions\km0AH\src\univariate\continuous\kolmogorov.jl:27  
…  
Is there any issue in my BenchmarkTools package? Its version is 1.4.0

Works fine for me - have you somehow managed to shadow `median`? The method `median(::Vector{Float64})` does exist unless you’ve somehow shadowed it.

Maybe, my friend also could run it successfully. How to confirm if I shadowed `median(::Vector{Float64})` , and if it is true, how to fix it?

Do you have `median =... ` somewhere in your code?

No, only below two lines of code:  
using BenchmarkTools  
@benchmark sort(data) setup=(data=rand(10))

Try restarting the REPL (either click the bin icon on your REPL and start a new one, or you can use the restart repl command (ctrl-shift-p then searching restart repl might work)). Then run those two lines.

If it still doesn’t work please provide the complete error.
