Confusing error when updating packages in Julia 0.5.0

When attempting to update the installed packages on my Windows 10 laptop with Julia 0.5.0 installed, the following error appeared with regard to Rmath:

================================[ BUILD ERRORS ]================================


WARNING: Rmath had build errors.

 - packages with build errors remain installed in C:\users\caitling\emacs251\.ju
lia\v0.5
 - build the package(s) and all dependencies with `Pkg.build("Rmath")`
 - build a single package by running its `deps/build.jl` script

================================================================================

I am also confused by the inability of Julia to locate 'Gadfly.jl' despite the fact that it is installed as the above output would indicate.

Thank you.

Solution

It could be due to the path to your package directory being case sensitive. I had the same problem after specifying a local package directory until I realised, thanks to this discussion, that I had the wrong capitalisation in the specified path.

I'm pretty sure C:\\users should be C:\\Users but check the rest of your path which is currently:

C:\users\caitling\emacs251\.julia\

you can then check if this is the problem by

ENV["JULIA_PKGDIR"] ="C:\\Users\\caitling\\emacs251\\.julia"
Pkg.build("Rmath")
