Hello everyone,

A few days ago I started programming julia and now I got stuck.  
My final goal is to plot with Julia, but for this I need Conda - and here comes my problem:  
When I execute Pkg.build(“Conda”) I get

```julia
ERROR: LoadError: ArgumentError: isdefined: too few arguments (expected 2)
Stacktrace:
 [1] top-level scope at none:0
 [2] include at .\boot.jl:317 [inlined]
 [3] include_relative(::Module, ::String) at .\loading.jl:1038

 [5] include(::String) at .\client.jl:388
 [6] top-level scope at none:0
in expression starting at C:\Users\benej\.julia\packages\Conda\a196m\deps\build.jl:7

```

Could anybody help me?  
Regards,

Ben

Hi Ben,

from the file path given in your error message I asume you are running Julia on Windows OS.

Which package do you want to use for plotting? I had a lot of trouble with the Python-related/-dependent packages as well, because I don’t have Python installed.

As I am using Juno (from JuliaPro) I found it easier to use PlotlyJS (Java Script-based plotting).  
Would that be an option for you as well?

Best

Moses

See [here](https://github.com/JuliaPy/Conda.jl/issues/112). Apparently this should be fixed in Conda v1.0.1 … try `Pkg.update()`.

Hello,

thank you for your messages.  
@crbinz: I use conda 4.5.4 and I think until now julia 1.0.0 is the most actual version.  
‘Pkg.update’ did not solve my problem… Do you have any other idea?

@Moses: I just want to have a possibility to make some easy plots.  
PlotlyJS seems to be a good alternative.  
Now on 'Pkg.build(“PlotlyJS”) I get

If you just started using Julia, use 0.7, not a prerelease of 1.0.

I meant that `Conda.jl v1.0.1` is the version that should fix this issue. Can you check the installed version of `Conda.jl` with `] status`?

I did not know about the prerelease status of Julia 1.0.0,  
after I switched to 0.7.0 it works fine.  
For the first, I will go on like this.  
Thank you guys!
