manim TextMobject not work with exception "Latex error converting to dvi

Question

My computer is Windows 10 64bit, and I install python 3.7.3 32bit, and MikTex 2.9 32bit, manim master from git at around june 2019 (one or two weeks ago) and other dependencies, finally I can run SquareToCircle successfully.

However when I add a makeText class to example_scenes.py and run as below:

class makeText(Scene):
    def construct(self):
        first_line = TextMobject("Manim is fun")
        second_line = TextMobject("and useful")

        second_line.next_to(first_line, DOWN)

        self.wait(1)
        self.play(Write(first_line), Write(second_line))

Issue below command in windows command line window:

c:\software\manim>python -m manim example_scenes.py makeText -pl

Exception pops:

Media will be written to ./media\. You can change this behavior with the --media_dir flag.

    "See log output above or the log file: %s" % log_file)
Exception: Latex error converting to dvi. See log output above or the log file: ./media\Tex\6b85ca5665e2f414.log

Actuall I cannot find 6b85ca5665e2f414.log but a 6b85ca5665e2f414.tex and a 6b85ca5665e2f414.pdf.

Anyone can help me please, thanks!

===============================================

update (June 28, 2019): Did some debug and found below code caused the exception (line 61 of tex_file_writing.py):

exit_code = os.system(" ".join(commands))

the exit_code is 1, and the commands begin with "latex...."

I followed this, and it works, not sure why the fix was not merged into the master.
