Precompiling PlotUtils fails - LoadError, premature end of input

[ChantalJuntao]

I tried to precompile Plots, and got this error in PlotUtils (fully updated and built). I'm running Julia 1.1.1 on Ubuntu 16.04

using PlotUtils

Thanks for moving the issue over here!
It's weird, because I cannot reproduce the issue neither on the latest PlotUtils release nor on master.
Also, the lines that your error message refers to have not changed since commit 6fc51d9 2 years ago and I have never seen this issue before. Are you sure that everything is installed correctly and that you did not edit any file in PlotUtils?

[ChantalJuntao]

pkg status shows I'm using
[995b91a9] PlotUtils v0.5.8
[91a5bcdd] Plots v0.25.1

I don't think I've ever edited them before. Either way, shouldn't updating the package remove any edits I didn't commit?

I also just saw this error on a CI run. Not sure what's causing it, will try to dig deeper...

For what it's worth, it works on my machine.

@daschw, a rerun of the same Gitlab CI job shows no error, so I assume it was a temporary glitch from somewhere.

A solution could be to rm -rf ~/.julia/packages/PlotUtils (or wherever the PlotUtils package lives) and then ]instantiate. @ChantalJuntao, please tell us if this works for you!

This is an upstream error in Julia, confirmed by @KristofferC. First reported at JuliaLang/Pkg.jl#795 and PR to fix it at JuliaLang/julia#30989.

Thanks a lot for the detective work @asinghvi17 !
