Package under Windows with Anaconda Python fails

[DavidLP]

Although pdflatex is added to the path variable I cannot get this package to work under Windows 10. The traceback when running the example is:

(base) C:\Users\David\git\latex>python sample_test.py
Traceback (most recent call last):
  File "sample_test.py", line 3, in <module>
    r = build_pdf(open('sample.latex'))
  File "C:\Users\David\git\latex\latex\build.py", line 232, in build_pdf
    return builder.build_pdf(source, texinputs)
  File "<decorator-gen-1>", line 2, in build_pdf
  File "C:\Users\David\Miniconda2\lib\site-packages\data\decorators.py", line 82, in _
    return f(*bvals.args, **bvals.kwargs)
  File "C:\Users\David\git\latex\latex\build.py", line 113, in build_pdf
    raise_from(LatexBuildError(base_fn + '.log'), e)
  File "C:\Users\David\Miniconda2\lib\site-packages\future-0.16.0-py2.7.egg\future\utils\__init__.py", line 454, in raise_from
    raise e
latex.exc.LatexBuildError: None

My environment:

• Windows 10
• Anaconda Python 2.7.15
• pdfTeX, Version 3.14159265-2.6-1.40.19 (MiKTeX 2.9.6800 64-bit)

To augment this with a minimal example:

python -c "import latex; latex.build_pdf(r'\documentclass{article}\begin{document}Hello\end{document}')"
Traceback (most recent call last):
  File "C:\Users\dahanna\AppData\Local\Continuum\anaconda3\envs\cleanEnvToInstallCorText\lib\site-packages\latex\b
uild.py", line 111, in build_pdf
    stderr=open(os.devnull, 'w'), )
  File "C:\Users\dahanna\AppData\Local\Continuum\anaconda3\envs\cleanEnvToInstallCorText\lib\subprocess.py", line
347, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['latexmk', '-pdf', '-pdflatex=pdflatex -interaction=batchmode -halt-on-er
ror -no-shell-escape -file-line-error %O %S', 'C:\\Users\\dahanna\\AppData\\Local\\Temp\\tmpj2ugc6le\\tmp_7anpuy3.
latex']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\dahanna\AppData\Local\Continuum\anaconda3\envs\cleanEnvToInstallCorText\lib\site-packages\latex\b

  File "<string>", line 1, in <module>
latex.exc.LatexBuildError: None

This is likely related to #7 (comment)

Using the error-capture from #27 yields:

b"Latexmk: This is Latexmk, John Collins, 18 June 2019, version: 4.65.\nLatexmk: Filename 'C:\\Users\\dahanna\\App
Data\\Local\\Temp\\tmpboep692o\\tmpdyaq0rmd.latex' contains character not allowed for TeX file.\nLatexmk: Stopping
 because of bad filename(s).\n"

I think we're running into the same latexmk problem as atom-latex: thomasjo/atom-latex#480

For me, #28 resolved the error.
