Trying to create Package get error

If you have Base checked out for development and have  
│ added xxx as a dependency but haven’t updated your primary  
│ environment’s manifest file, try `Pkg.resolve()`.  
│ - Otherwise you may need to report an issue with Base  
└ Loading xxx into Base from project dependency, future warnings for Base are suppressed.

How to resolve this  
Pkg.resolve() didnt help

This is a very strange error. For other packages it often means that you have added a new package dependency to a package that you have `develop`ed (because it is yours and you are developing it, or because you are making a patch for that package), and now a package that makes use of your `dev`ed package is lost because the dependencies of the package changed within the same version.

In your case, how do you ended up the `Base` library checked out for development? Are you contributing to Julia?

No not contributing to Julia  
Was trying to create Package using PackageCompiler which was giving error so had tried out update; precompile and that’s when the error occured

The utility of PackageCompiler is not for creating a package (at least to my knowledge), but to compile the dependencies of a script so you either: (i) get a binary, or (ii) you can use the REPL to execute workflows similar to the script with less startup time. Can you tell us more about what are you trying to achieve?

Was trying to create exe.  
Used create\_app(“.”, “./dummy”)  
and that shows some dependencies error  
and hence tried precompile after reading in forums and got this error

The error on create app was as follows  
Stacktrace:

with couple of warnings as  
xxx has a build script, this might indicate that it is not relocatable  
xxx has a dependency on Requires.jl, code in `@require` will not be run

but that information didnt help much in knowing where exactly the error is occuring in creating package

This may be a problem in itself, but seems unrelated to the problem in the stacktrace.

The stacktrace seem to show an error in the copying of the files to create the bundle. I am not sure this is related with the message in your original post, about the Base dependencies, and that message was a warning not an error so it may be a red herring.

Not sure, why the create\_app gives error in creating bundle, create\_app error shows the error  
Trying to create .exe out of the julia files

Just encountered the same problem when I tried to generate a pkg from a bunch of scripts I had lying around.  
What I did was to copy all scripts into a `src/` folder, added a pkg file `src/MyPkg.jl` with all the includes, as well as a `Project.toml` file with all the dependencies (including `name, uuid, authors, version`).  
Starting with `julia --project` and running `using MyPkg` gave me the above error.

It took me a while to realize the problem: I had forgotten to wrap everything inside `src/MyPkg.jl` into a `module`, e.g. it should look like

```julia
module MyPkg

# includes go here

end # module

```

Restarting and `using MyPkg` then worked (maybe do a `resolve`/`instantiate` before).

Moral of the story:  
Although, I thought generating the pkg structure by hand isn’t so difficult, it took me a few minutes to get it right. I guess this just proves that one should always use `Pkg.generate()` when making a fresh package.
