How to add a package in Julia

While adding a new package I get the following error on Julia.

julia> Pkg.add("IJulia")
 Resolving package versions...
ERROR: SystemError: opening file C:\Users\ARPAN\.juliapro\JuliaPro_v1.0.3.1\registries\JuliaPro\C\Co
lor\Versions.toml: No such file or directory

Can anyone help?

This path looks to be missing \ in the middle. Should be ...\ARPAN\.juliapro\....

One option is to set the environment variable JULIA_DEPOT_PATH (executed at the command line):

set JULIA_DEPOT_PATH=C:\Users\ARPAN\.juliapro\JuliaPro_v1.0.3.1

julia

And now once Julia is started install the packages. You can check that the above path is correct by running versioninfo() from Julia.

The question is why it did not work in the first place. Most likely you have wrongly set one of JULIA_* environment variables. For a complete list see https://docs.julialang.org/en/v1/manual/environment-variables/index.html.
