check_latex can't find pg.sty

[dlglin]

When I run check_latex I get "! LaTeX Error: File `pg.sty' not found."

A bit of digging shows that the value of $ce->{pg}{directories}{assetsTex} is "/assets/tex", which is not correct.

I believe that the problem is that $pg_dir is defined in webwork2.mojolicious.yml (or the .dist version), but when a WW CE is invoked from the command line the mojolicious config is not loaded, so $pg_dir is never set, which means that any paths that are built from that will be incorrect.

If I'm right this means that check_latex won't work for anyone in 2.19. Can someone confirm whether it works for them?

I confirm on the two 2.19 servers that I checked, that I get the same error about pg.sty.

When I check this on my production servers (PCC and RS) check_latex fails. But just now I was testing Glenn's PR to address this. And I found that on my devleopment server, on the develop branch, check_latex runs with success. (On the develop branch, not just with Glenn's fix.)

You probably have the PG_ROOT environment variable set. If you have set to the PG directory, then the script will still succeed, because it finds the PG directory that way rather than the new way of getting it from the configuration file.

By the way, when @dlglin first posted this issue and I tested it, I saw the same thing. Then I unset PG_ROOT and tried again. Then I saw the failure.

This was fixed by #2545 and hotfix #2546.
