我的电脑是 Windows 10 64bit，我在 2019 年 6 月左右（一两周前）从 git 安装了 python 3.7.3 32bit，MikTex 2.9 32bit，manim master 和其他依赖项，终于可以成功运行 SquareToCircle。
但是，当我将 makeText 类添加到 example_scenes.py 并运行如下：
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))
在 windows 命令行窗口中发出以下命令：
c:\software\manim>python -m manim example_scenes.py makeText -pl
异常弹出：
Media will be written to ./media\. You can change this behavior with the --media_dir flag.
Traceback (most recent call last):

"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
实际上，我找不到 6b85ca5665e2f414.log，但找不到 6b85ca5665e2f414.tex 和 6b85ca5665e2f414.pdf。
任何人都可以帮助我，谢谢！
===============================================
更新（2019 年 6 月 28 日）：做了一些调试，发现下面的代码导致了异常（tex_file_writing.py 的第 61 行）：
exit_code = os.system(" ".join(commands))
exit_code 为 1，命令以“latex....”开头
