Installing QML.jl

@jtravs To my surprise, the new test binaries to prepare for the release worked on my wife’s PC (win10, 64 bit Julia 0.5), following the Readme:


Feel free to test, apart from the GLVisualize example everything should be as in the planned release. A good place to start is example/gui.jl

When I try to update (I even removed it to try again). Don’t understand the complain.

julia> Pkg.clone("")

ERROR: fixed packages introduce conflicting requirements for CxxWrap:

Did you run Pkg.update() first? It requires a CxxWrap from 2 days ago.

Yes, ofc. I even removed/reinstalled it.

@barche Excellent. It now works as you say, and has perfect HiDPI rendering. Very happy indeed. Thanks for getting this up and running!

Unfortunately the packaging system is still very fragile. One problem somewhere propagates to a point where I fear the only solution it nuke all and start over. GLVisualize doesn’t want to work now either. And when I try to remove it … it installs its dependencies.

julia> Pkg.rm("GLVisualize")
INFO: Cloning cache of GLAbstraction from

Hmm, it seems your package metadata is somehow out of sync or out of date, CxxWrap 0.1.8 is definitely in there:

To nuke it and start over, just copy the REQUIRE file from .julia/v0.5 somewhere else, remove .julia, put back the REQUIRE file, and do Pkg.update(). This will re-install the same packages.

This is actually something I recommend to do from time to time!

Yes, but it would be better not having to do it. And for that it would help if Pkg.rm() REALLY removed the package instead of hiding it under .trash & .cache

help me, I have a problem, I don’t know what is this error? how to fix it? (sorry for any mistakes, I’m not good at english!)pic1

Do you have a way to slove it now? I have the same problem as you
