#2297 kpsewhich: on-the-fly installation crashes

kpsewhich (1)

I have set the on-the-fly to "ask me first". If I query with kpsewhich a package which is not installed on my system, eg. bg.sty from the backammon package with

 kpsewhich bg.sty

then the on-the-fly-installation dialog pops up and asks me if I want to install the package. That's a problem if kpsewhich is used in scripts to get the location of files. Imho kspewhich should not by default start the on-the-fly installation.

(I know that kpsewhich is not the official tool to find files, but it makes life easier if you have to write scripts meant for texlive and miktex).

    It should be possible to disable the auto-installer as follows:


    In the future I will add a MiKTeX specific option to disable the auto installer.

    I added the environment variable to my settings and it works fine. Thank you.

    Actually, for me the on-the-fly installation is quite nice. But if it's set to install without request ("Install missing packages on-the-fly: Yes"), there's an error message after an automatic installation:

    "Standalone path lookup and variable expansion for Kpathsea funktioniert nicht mehr"

    I will not change the MiKTeX program invariant:

    files will always be found if the installer is not disabled

    I will fix the application crash reported by mrpiggi.
