Hi,  
To install a local package I usually use `] add` or `] dev` + the path to the package folder. Is there a way yo install a package at a specific version?

Something like : `] add c:/MyPackage@0.0.2`

If I want to install at a specific commit it seems the following is working:

`] add c:/MyPackage#12345gd2`

(By the way the progress bar is totally messed up when I use the above command in Windows)

Thank you

I guess you can install at the commit that corresponds to the version release tag, but manually finding that can be extra work.

This is about dependencies of a project, but have a read of [6. Compatibility · Pkg.jl](https://pkgdocs.julialang.org/v1/compatibility/)  
Among other useful information, it has this statement:

> There is currently no way to give compatibility from the Pkg REPL mode so for now, one has to manually edit the project file.

It seems `add` of a local directory with a version number is explicitly disallowed: `add /path/to/package @1.0` returns  
`ERROR: version specification invalid when tracking a repository: `1.0` specified for package `/path/to/package` `

For one-off usage, you can get the commit corresponding to a tag wtih `git rev-list -n 1 v0.0.2` ([source](https://stackoverflow.com/a/1862542/8127)) on the command line and add with that commit hash.

If you have need to do this regularly with a package, a [local registry](https://github.com/GunnarFarneback/LocalRegistry.jl) might make this easier.

If you have a git tag corresponding to your version you can add with `path#tag`.
