Pkg.update() seems to have broken my Plots install



Given the trouble i was having with pyplot i decided to try and intall GR
it did this:

INFO: Precompiling module GR.
WARNING: Module Compat with uuid 3037559065285 is missing from the cache.
This may mean module Compat does not support precompilation but is imported by a module that does.

so i did and now GR is downloading the same linux pre-complied binary it did the first time i tried to add it.

Alll of this seems to have started after I did a Pkg.update.
Should I just kill the package directory and start over ?
No matter what the language, package handling seems to be very fragile.


This is a known issue due to precompilation that can come up. A quick fix is to delete your ~/.julia/lib folder (contains the precompilation caches).


Usually just restarting Julia fixes this.


restarting julia definitely didn’t fix it.
i deleted everything in .julia and started over.
edit: that did the trick.


I ran into this issue this week. My special wrinkle: I have JULIA_PKGDIR set to point to a non-default location (a network share, in fact). Deleting the lib/v0.6 directories in both the usual place and under the directory specifed by JULIA_PKGDIR and restarting was insufficient to fix things for me. The extra tweak I made that got things to work was to prepend the <my_pkgdir>/lib/v0.6 path to Base.LOAD_CACHE_PATH and then rebuild the failing packages.
