I have created a package using [PkgTemplates](https://github.com/invenia/PkgTemplates.jl), and everything is great. Now I want to use this package on another machine. I have copied the files. How do I add the path of the directory such that `Pkg` knows about it when I do `add MyPackage`?

You just need to supply the path to the package when you call add.

```julia
add /home/Packages/MyPackage

```

for example.

That needs to be a git repository according to the docs.

Better to `] dev path/to/package`

Even better, OP, would be to put the package on github. Then you can add the git url and keep updated across machines.

If he used PkgTemplates it should be a git repo I believe. But yes, might as well put it on Github, even if you just make it a private repo.

It does not work for me. It seems like the package is added, but after doing `using MyPackage` it cannot recognize any of the function…

So `using MyPackage` works without error but not executing any of the functions?

Please post the error messages. Are you sure your `MyPackage` is `export`ing the functions? Can you call `MyPackage.foo`?

Yes. On my 1st machine everything works great.  
On the other machine it doesn’t. the error message is just

```julia
julia> MyPackage.foo
ERROR: UndefVarError: foo not defined

```

what does your `src/MyPackage.jl` code look like?

BTW, I would upload this to git to solve the problem, but I am not sure how to do that. I tried to create a new repository on GitHub, and then to push. But I think that the `PkgTemplates` already set the remote, and therefore I can’t do it now.  
Do you know how to make it work?

I’m not sure if PkgTemplate would have set the remote or not. You can do

```julia
git remote -v

```

from the command line or a Git shell to see what your remotes are set as.

My typical workflow

- create package locally, get it partially working
- create repo on Github website. just leave it empty when you create it.
- set `origin` on my local repo to be the newly created remote repo. I use the `ssh` version because I have previously setup ssh keys. `git remote add origin git@github.com:username/reponame.git`
- `git push -u origin master` to push everything to remote (assumes you have master checked out)

This is what I did. But I get get permission denied error:

Then you have set the repo as private and you have not properly set up ssh access from that computer. Once you set up ssh keys with Github it should work fine.

Thanks. I will try.

But anyway, there is not way to simply let `Pkg` know about a local package?

I do not understand what the `PkgTemplates` did so that I can simply do `add MyPackage` in the first machine. Can’t I do it in the second machine?

My intuition is that it’s overkill to get set up on git just to fix this problem. I think there must be some step you missed in getting set up. Can you try and give an MWE (or, list your steps) for how you got set up?

I have generated my package using a template with `PkgTemplates`, and everything is working great.

On my 1st machine I have been using this packages successfully from day one.

Now, I want to use the package on my other machine (I have dropbox connecting them, so the same folder is simply on my other machine as well).

When I do `add MyPackage` on the other machine, it looks fine. things are happening:

```julia

but as you can see, I can’t access the functions in the package.

Does it work if you do `dev` instead of `add`?

I tried `dev` and it might help.  
I did not see any change. But then I exited julia, and started it again. Now `using MyPackage` works just fine!!!
