With newly installed (upgraded) Lyx 2.3.0, whenever I try to add a Biblatex bibliography, I am getting this error box:
Lyx: package not available The cite engine biblatex requires a package that is not available ... or a converter that you have not installed... Missing prerequisites: biblatex.sty ... Background: I've just updated to Lyx 2.3.0 via the Windows installer (for which, many thanks). A key reason for me to upgrade is the native Biblatex support. With Lyx 2.2, I got Biblatex working fine via the tricks described in the Lyx Wiki--- so my system is/was basically OK I reckon. But I can't get biblatex biblios going with Lyx 2.3.0. More details below. Any thoughts? - This is Windows 10 64 bit, Miktex 2.9. - Documents without biblios seem to work fine (ie produce PDFs) and Miktex has been happily installing packages on-the-fly at Lyx's request. - kpsewhich biblatex.sty (in a command window) finds the file, no problem. - the biblatex.sty file lives underneath one of the "TEXMF root directories" that Miktex knows about (I am out-of-my-depth on that stuff, but I - This happens both with a brand-new document (Article/Standard class, no modules, no local layout, a few lines of text) when I try to add a biblio, and also with a 2.2-format document when following the instructions in "How to transition from using Biblatex in LyX 2.2 and earlier to native support in LyX 2.3" on the Lyx Wiki. - Happens whether I set Document->Settings->Biblio->Citation_style->Style_format to "biblatex" or to "biblatex( natbib)", though the name of the cite-engine in the error box changes. - The exact same issue has occurred on my two machines where I've just upgraded to Lyx 2.3. In one case, I did a complete Miktex reinstall *after* installing Lyx 2.3, but in the other I used my previous Miktex. Since I already had working Miktex 2.9 with Lyx 2.2, I used the Installer "LyX-230-Installer-6.exe", not the Bundle (then, on one machine, I re-installed Miktex directly). - Tools->Tex_Information->Latex_styles does show "biblatex.sty". There are lots of entries in the "Biblatex citation styles" and "Biblatex bibliography styles", too. - FWIW: in Tools->Preferences, I have TEXINPUTS set to "." and PATH_prefix set to "$LyXDir\bin;$LyXDir\Python;$LyXDir\Python\Lib;$LyXDir\Perl\bin;$LyXDir\imagemagick;C:\miktex\miktex_2.9\miktex\bin\x64;C:\Rtools\Rtools34\mingw-64\bin;C:\Rtools\Rtools34\bin;C:\R\R-3.3.3\bin\i386;C:\PROGRA~1\Git\bin". The same issue happens whether I remove or include the miktex folder there. Mark Bravington CSIRO Marine Lab Hobart Australia
