Hello,

I was trying to update an old package that I wrote in order to be able to register it and run `gen_package.jl` as described in the `Pkg` doc and suppressed my `REQUIRE` file. The problem is now that I have made further modification to the package but the `project.toml` won’t update itself and so the new dependencies are not taken in acount.

Do you know how I can manually update the `project.toml` file so that I’ll be able to register my package ?

If the code of `MyPackage` is in the path `~/.julia/dev/MyPackage`, type:

```julia
] activate ~/.julia/dev/MyPackage

```

(Use the path that is suitable to your case).

This should activate the enviornment of that package — you’ll see `(MyPackage) pkg>` in the prompt. And then, if the dependencies of the package are `Foo` and `Bar`, just add them (still in the package management mode):

```julia
add Foo
add Bar

```

This will populate the `Project.toml` with the suitable lines. Enter `activate` (with no argument) to go back to the default environment, when you are done.
