Question

此脚本使用pythontex创建一个laTeX版本的ask.tex。 python代码包含subprocess，完整的python代码runme.py是

#Python 3.4.3
import sys
import os
import re
import subprocess
import shutil


subprocess.call(['pdflatex', 'Ask.tex'])
subprocess.call([sys.executable, 'pythontex.py', 'Ask.tex'])
subprocess.call(['pdflatex', 'Ask.tex'])

和LaTeX代码ask.tex是，

\documentclass{article}
\usepackage{ragged2e}
\usepackage[utf8]{inputenc}
\usepackage[letterpaper, top=0.5in, bottom=0.5in, left=1.55in, right=1.55in]{geometry}
\usepackage{multirow,array,varwidth,spreadtab,caption}
\usepackage[norule]{footmisc}
\usepackage{color, colortbl}
\usepackage{xcolor}
\usepackage{multicol}
\usepackage{pythontex}

mycursor.execute(query)

    print("{}".format(row[0]))
mycursor.close()
conn.close()

Pythontex需要3个步骤来编译文件，首先运行pdflatex，然后运行'pythontex file.py'，然后再次运行pdflatex。

我将runme.py和ask.tex放在pythontex的文件夹下，该文件夹包含pythotex.py文件。

在IDLE模式下运行runme.py后，可以执行pdflatex，并弹出cmd提示窗口并完成没有问题。 但问题是，我看不到pythontex.py正在运行，导致输出pdf文件没有变化。

感谢您对此问题的任何评论和帮助。非常感谢。

[更新] 我编写了python代码，

import sys
import os
import re
import subprocess
import shutil


subprocess.call(['pdflatex', 'Ask.tex'])
try:
    subprocess.call(['pythontex', 'Ask.tex'])
except:
    subprocess.call(['pythontex.py', 'Ask.tex'])
subprocess.call(['pdflatex', 'Ask.tex'])

同样，pdflatex可以被执行，但是，有一些错误，

Traceback (most recent call last):
  File "C:\Users\Cheng\Desktop\LaTeX Project\pythontex\runme2.py", line 10, in <module>
    subprocess.call(['pythontex', 'Ask.tex'])
  File "C:\Python34\lib\subprocess.py", line 537, in call
    with Popen(*popenargs, **kwargs) as p:
  File "C:\Python34\lib\subprocess.py", line 859, in __init__
    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\Cheng Zhang\Desktop\LaTeX Project\pythontex\runme2.py", line 12, in <module>
    subprocess.call(['pythontex.py', 'Ask.tex'])
  File "C:\Python34\lib\subprocess.py", line 537, in call
    with Popen(*popenargs, **kwargs) as p:

    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
OSError: [WinError 193] %1 is not a valid Win32 application

那是新问题。 核心问题，pythontex无法运行。

Answer 1

经过一番研究，我发现这种方式可以很好地解决问题。

#Python 3.4.3
import sys
import os
import re
import subprocess
import shutil


subprocess.call(['pdflatex', 'ask.tex'])
try:
    subprocess.call(['pythontex', 'ask.tex'], shell=True)
except:
    subprocess.call(['pythontex.py', 'ask.py'], shell=True)
subprocess.call(['pdflatex', 'ask.tex'])

关键部分是add shell=True，否则Python不会识别该语句。

子进程pythontex无法正常工作
