iftex.sty missing #140

Closed JonDoyle closed 4 years ago

JonDoyle commented 4 years ago

After updating my packages, it appears that the file iftex.sty loaded by ifluatex.sty has disappeared.

In my installation files, iftex.sty does not appear under tex/generic/iftex, nor under tex/latex/iftex.

Every attempt to recompile my file, in which none of the packaging information has changed, instigates an attempt to download the package. Across numerous attempts, the result is the same, no matter what mirror is used. The MiKTeX log file refers to some other program having use of the file, but this happens even when compilation takes place after rebooting my machine and with no prior invocations.

My MWE, trial.tex attached, does nothing but load the package.

Duplicate of #138

So the obvious workaround is: make sure that package iftex is installed.

JonDoyle commented 4 years ago

The problem does not seem to be that the iftex package is not installed. It was installed (and had been for years) at the time the error occurred, and as my error report stated, when I checked the iftex directory, iftex.sty was not in it (though some others were there).

Just to be sure, I ran the package installer via the MiKTeX console only to discover it listed iftex as uninstalled. I (re)installed it, observed that it put the missing files back in the iftex directory. I then reran pdflatex, but the error reoccurred, invoking the on-the-fly package installer. But when I check the iftex directory after this, only two of the files placed there by the installer are still there, and iftex.sty is one of the missing ones.

So something is going wrong somewhere. I am only doing ordinary things, with nothing changing in my installation (regularly updated). Unless there is some Windows 10 change that might be causing this.

Thank you for any help you can offer.

As in my original report, this happens even after a reboot with nothing but Emacs running, so I have no idea what other process might be causing the Windows API error.

@JonDoyle Sometimes a simple update does not refresh the package database that is used for on-the-fly installation. This is especially true on an Admin-&-User system.

Just to be sure that no command is hogging the files you may want to reboot your machine before you go through with the following. Don't start any other TeX-related software before or while going through these steps - only use the MikTeX Console.

Update MikTeX via the MikTeX Console in Admin mode and in User mode. Then open the Console in Admin mode and run Tasks > Update package database, repeat this step in User mode as well.

Cross your fingers and hope that this works. If it does not, remove iftex and all other older if...tex packages in both Admin and User mode (if installed) and re-install only iftex in either Admin or User mode (but not in both).

JonDoyle commented 4 years ago

Thanks very much, I'll try this.

Hi @JonDoyle, Could you please outline the steps you performed that made it work?

JonDoyle commented 3 years ago

It has been over a year since I had this trouble, so my memory might be slightly off. But as best I recall following the steps recommended by moewew as follows worked.

I run an Admin+User installation, and sometimes for that one apparently needs to refresh the package database for both the Admin and the user accounts.

  1. Open MikTeX console in Admin mode, then run Tasks > Update package database.
  2. Close the console and open it in User mode, then run Tasks > Update package database. *** I am not sure if doing these steps in this order worked. Try the reverse order if it does not. If neither works, try doing it AUA, or UAU. I'm pretty sure I did not need to run both modes twice.

Hope it works for you.
