I built the system image but it failed consistency check when I restart Julia, even though it said “System image successfully built”. MacOS. Anyone had success before and is there any advice? thanks

```julia
$ /Applications/Julia-0.7.app/Contents/Resources/julia/bin/julia 
ERROR: System image file failed consistency check: maybe opened the wrong version?

```

There is [an issue](https://github.com/JuliaLang/julia/issues/27201) on this, with a fix in progress. But apparently what the developers would like us to do now is

```julia
using PackageCompiler
build_sysimg(...)

```

Mmm… couldn’t get PackageCompiler to work though:

```julia

 - If you have PackageCompiler checked out for development and have
   added Sys as a dependency but haven't updated your primary

 - Otherwise you may need to report an issue with PackageCompiler.

That’s nasty, and I don’t know how to fix it. (`Sys` is in `Base`, so that should not happen.)

Meanwhile, what looks to be a fixed version of the old script (from [the PR I alluded to above](https://github.com/JuliaLang/julia/pull/27629)) is  
[here](https://github.com/JuliaLang/julia/raw/5b1ec9c2c8534353cd9e74503f7e748d3b42089d/contrib/build_sysimg.jl)

That works, thanks!

P.S. …although the new sys img is making my program 10x slower than 0.6… investigation to be continued…

I could load PackageCompiler (master branch) with no problem on 0.7.
