Re: run error Lilypond-book on Windows 10

[Archer Endrich]

Thank you Knute and David!  I have downloaded and installed MiKTeX and 
rerun my batch file (without the .py added to lilypond-book).

It appears to have called lilypond-book successfully and also pdflatex.  
However, it still reports an error in lilypond-book.ly which is 
preventing compilation.

Here is the output:

C:\P3L\lpbk>ALMdurasnumber.bat

C:\P3L\lpbk>lilypond-book --output=out --pdf ALMdurasnumber.lytex
  File "C:\Lilypond2221\usr\bin\lilypond-book.py", line 376
    except subprocess.CalledProcessError as e:
                                          ^
SyntaxError: invalid syntax

C:\P3L\lpbk>cd out

C:\P3L\lpbk\out>pdflatex ALMdurasnumber.tex
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (MiKTeX 21.6)
entering extended mode
! I can't find file `ALMdurasnumber.tex'.
<*> ALMdurasnumber.tex

Please type another input file name:

So it all seems to be working except for the reported error.

Regarding paths, I had renamed my lilypond directory with a version 
number, and updated my Windows path accordingly,  Lilypond itself has 
been running fine, so, as far as I can tell, the paths are OK (and it 
was happy without the .py extension in the batch file).

Perhaps someone could check out line 376 for me.  Thanks again.
