I am trying to run some open code from github

The package is not a registered one, so it is suggested to add the package from the local path. I have downloaded the package to my C disk, but cannot add it successfully,

```julia
(harmonic_oscillator_1d) pkg> add C:\Users\jmzhang\Downloads\FermiFCI.jl-master\src\FermiFCI
ERROR: `C:\Users\jmzhang\Downloads\FermiFCI.jl-master\src\FermiFCI` appears to be a local path, but directory does not exist

```

what is the problem?

You don’t need to clone it, you can do

```julia
]add https://github.com/rammelmueller/FermiFCI.jl

```

Looking at your original error you have

```julia
add C:\Users\jmzhang\Downloads\FermiFCI.jl-master\src\FermiFCI

```

but maybe you meant

```julia
add C:\Users\jmzhang\Downloads\FermiFCI.jl-master\

```

Can you `git clone`?

Otherwise you will need to dev the package.

You can follow these steps:

1. clone the repo in the shell, not downloading the zip on the GitHub website.

```sh
git clone https://github.com/rammelmueller/FermiFCI.jl

```

1. add the package in the Julia REPL.

```julia
(jl_NFHhDT) pkg> dev /path/to/FermiFCI.jl

```

Then you can use the package directly.
