#### Post date: [March 9, 2024, 4:42am UTC](https://discourse.julialang.org/t/using-a-local-package/111387/1 "2024-03-09T04:42:00Z")
I downloaded a [package](https://github.com/yomichi/SpinMonteCarlo.jl) from github, so I have all the source codes.
To run an example code, I have to install the package first using pkg as suggested by the author. However, that failed.
Is it possible to run the code using the local files?
The first line of the example code is
```julia
using SpinMonteCarlo
```
I have copied the example code to the same directory as the file SpinMonteCarlo.jl. But I still got the error:
```julia
ERROR: LoadError: ArgumentError: Package SpinMonteCarlo not found in current path.
- Run `import Pkg; Pkg.add("SpinMonteCarlo")` to install the SpinMonteCarlo package.
```
How to fix the problem?

Did you try:
```julia
mkdir Spin
cd Spin
julia --project="."
```
and then in Julia
```julia
]
add SpinMonteCarlo
```
Does this work? I get one warning, but no error.
Quit Julia, restart it with
```julia
julia --project
```
and try again
```julia
using SpinMonteCarlo
```
Does this work? If not, what is the error message?

Since you were asking how to install a package that you already cloned from Github, the relevant parameter for `Pkg.develop` would have been `path`. I would strongly recommend that you start to read documentation and do some basic investigation before asking here.
I do not believe you are installing into a clean environment. In a clean environment, the `SpinMonteCarlo` package installs without problems. Did you try the instructions in [Using a local package - #3 by ufechner7](https://discourse.julialang.org/t/using-a-local-package/111387/3)?

Now I can add the package, but I still cannot use it.

Yes.
```julia
$:~/SpinMonteCarlo.jl> julia
(@v1.10) pkg> activate --temp
(jl_xYmywU) pkg> dev .
julia> include("example/simple.jl")
```
Or if you prefer the more explicit version, from a folder `Spin` that contains a clone of `SpinMonteCarlo.jl`:
```julia
$:~/Spin> julia --project=.
julia> using Pkg
julia> Pkg.develop(path="SpinMonteCarlo.jl")
julia> include("SpinMonteCarlo.jl/example/simple.jl")
```
