Julia1.0 how to add the package ?

It’s not too clear what you’re asking. What have you tried already?

when i add Plots, there was an error：

(v1.0) pkg> add Plots
ERROR: The following package names could not be resolved:
 * Plots (not found in project, manifest or registry)
Please specify by known `name=uuid`.

What should I do?

Try

(v1.0) pkg> activate

(v1.0) pkg> add Plots

I don't know why it's the same mistake：

(v1.0) pkg> add Plots
ERROR: The following package names could not be resolved:
 * Plots (not found in project, manifest or registry)
Please specify by known `name=uuid`.

You probably don’t have the registry for some reason. Can you remove ~/.julia/registries and try again?

I have successfully installed Plots, but when i using Plots, there was an error:

 Is there any way you can solve this problem ?

Looks like Plots.jl hasn’t been tagged for 0.7/1.0 yet.

A workaround seems to be to add the master branch instead:

(v1.0) pkg> add Plots#master

(v1.0) pkg> add  https://github.com/JuliaPlots/Plots.jl#340cd0a1fe8bdddfb078e9fbd93d8cf4995cb134
