Hi,

I already know how to use Julia, I’m just checking out 1.0 for the first time and I’m wondering if I found a bug. I did this:

Press Enter to start Julia.  
Starting Julia…  
\_  
\_ \_ _(_)\_ | Documentation: [https://docs.julialang.org](https://docs.julialang.org)

julia\> using Plots  
ERROR: ArgumentError: Package Plots not found in current path:

- Run `Pkg.add("Plots")` to install the Plots package.  
[…]

I know about Pkg3, but here it doesn’t say anything about Pkg3, so I tried running the command it says to run.

julia\> Pkg.add(“Plots”)  
ERROR: UndefVarError: Pkg not defined  
[…]

I don’t need help with plots specifically. I was able to add this package by pressing ] and so on. I’m talking about what it says in the error messages.

Is this a bug or am I a moron?

Thanks,

S

You need `import Pkg`. A PR is open to clarify this [https://github.com/JuliaLang/julia/pull/28555](https://github.com/JuliaLang/julia/pull/28555). It will likely be in 1.0.1.

Sounds good. 🙂
