Can not install on Miktex 2.9.7364

[daviddhtn]

Please help, I cannot install webquiz on Miktex 2.9.7364, here are errors File: C:\Users...\AppData\Local\Programs\Python\Python37\lib\subprocess.py, line number: 487 Error Command 'kpsewhich -var-value TEXMFMAIN' returned non-zero exit status 1. in run: output=stdout, stderr=stderr) Traceback (most recent call last): File "webquiz.py", line 1124, in .format(metadata.repository), err) File "webquiz.py", line 808, in settings = WebQuizSettings() File "webquiz.py", line 237, in init TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFMAIN') File "C:\Program Files\MiKTeX 2.9\scripts\webquiz\scripts\webquiz_util.py", line 40, in kpsewhich return subprocess.check_output('kpsewhich ' + search, shell=True).decode('ascii').strip() File "C:\Users...\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 395, in check_output **kwargs).stdout File "C:\Users....\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 487, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command 'kpsewhich -var-value TEXMFMAIN' returned non-zero exit status 1.

The problem is the kpsewhich function in webquiz_util.py does not work in windows 10 Error in Line 40: subprocess.check_output('kpsewhich ' + search, shell=True).decode('ascii').strip() It should be modified like this subprocess.check_output(['kpsewhich','-var-value', search]).decode('ascii').strip() but some search term in webquiz.py must be edited

[AndrewMathas]

No, this is not the problem. The shell=True changes the syntax of the subprocess.check.output command. To confirm this I just checked this "by hand" on a windows 10 machine and it works fine:

subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True) kpsewhich: warning: running with administrator privileges b'C:/Program Files/MiKTeX 2.9\r\n'

According to your original error message the problem that you are actually having is with the command:

kpsewhich -var-value TEXMFMAIN

What happens when you run this in a terminal window? The expected output is something like the following:

kpsewhich -var-value TEXMFMAIN C:/Program Files/MiKTeX 2.9

Can you try installing with:

webquiz --debugging -i

and post the output around any error messages that you get.

Actually, I just test the simple code [code] import os import subprocess import webquiz_util TEXMFLOCAL='' try: TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFMAIN') except subprocess.CalledProcessError: pass

if TEXMFLOCAL == '': TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFLOCAL') print(TEXMFLOCAL) [/code] but it does not work, The error here [code] C:\Users...\Desktop\webquiz\scripts>python test.py The system cannot find the path specified. kpsewhich: security risk: running with elevated privileges The system cannot find the path specified. kpsewhich: security risk: running with elevated privileges Traceback (most recent call last): File "test.py", line 11, in TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFLOCAL') File "C:\Users...\Desktop\webquiz\scripts\webquiz_util.py", line 40, in kpsewhich return subprocess.check_output('kpsewhich ' + search,shell=True).decode('ascii').strip() File "C:\Users...\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 395, in check_output **kwargs).stdout File "C:\Users...\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 487, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command 'kpsewhich -var-value TEXMFLOCAL' returned non-zero exit status 1. [/code]

[AndrewMathas]

Since you are happy running python let's cut down to the actual problem. What does the following do:

import subprocess
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True)
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True).decode('ascii')
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True).decode('ascii').strip()

[AndrewMathas]

Btw, I notice that in the errors above sometimes you have a problem with TEXMFLOCAL and other times with TEXMFMAIN, which is a little strange.

[daviddhtn]

Hi AndrewAtLarge, That simple code does not work, C:\Users\NGOCTU\Desktop\webquiz\scripts>python test1.py The system cannot find the path specified. kpsewhich: security risk: running with elevated privileges Traceback (most recent call last): File "test1.py", line 2, in subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True) File "C:\Users\NGOCTU\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 395, in check_output **kwargs).stdout File "C:\Users\NGOCTU\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 487, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command 'kpsewhich -var-value TEXMFMAIN' returned non-zero exit status 1.

C:\Users\NGOCTU\Desktop\webquiz\scripts>python --version Python 3.7.2 "

Since you are happy running python let's cut down to the actual problem. What does the following do:

import subprocess
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True)
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True).decode('ascii')
subprocess.check_output('kpsewhich -var-value TEXMFMAIN', shell=True).decode('ascii').strip()

[daviddhtn]

I try to change the order of the search terms in webquiz.py so may be you can see the out put error at TEXMFMAIN or TEXMFLOCAL " TEXMFLOCAL='' try: TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFMAIN') except subprocess.CalledProcessError: pass if TEXMFLOCAL == '': TEXMFLOCAL = webquiz_util.kpsewhich('-var-value TEXMFLOCAL') self.system_rcfile = os.path.join(TEXMFLOCAL, 'tex', 'latex', 'webquiz', 'webquizrc') self.read_webquizrc(self.system_rcfile) "

Btw, I notice that in the errors above sometimes you have a problem with TEXMFLOCAL and other times with TEXMFMAIN, which is a little strange.

[AndrewMathas]

The problem is not with webquiz because the python code that I asked you to run simply executes:

kpsewhich -var-value TEXMFMAIN

from inside the python shell.

So I think that something must be wrong with your MikTeX configuration. What I do not understand, however, is why the kpsewhich command works for you when you run it from a terminal. As far as I can tell, python is finding the kpsewhich command BUT kpsewhich is not finding the TEXMFMAIN and TEXMFLOCAL environment variables.

[daviddhtn]

I don't know too, I think the problem may from the python version 3.7.2 64 bits. The Miktex run well.

I edit the code like below and It works well
import subprocess

import os

print(subprocess.check_output(['kpsewhich','-var-value','TEXMFMAIN']))

print(subprocess.check_output(['kpsewhich','-var-value','TEXMFMAIN']).decode('ascii'))

print(subprocess.check_output(['kpsewhich','-var-value','TEXMFMAIN']).decode('ascii').strip())

[AndrewMathas]

Strange. I don't understand this as both syntaxes for subprocess.check_output should work. Still, thanks for your detective work.

I can't attach a python file to this message. Can you try editting webquiz_util.py and replacing the kpsewhich function (line 34) with the following:

def kpsewhich(search):
    r'''
    Short-cut to access kpsewhich output.

    usage: kpsewhich('-var-value=TEXMFLOCAL')
    '''
    try:

        return subprocess.check_output(['kpsewhich']+search.split()).decode('ascii').strip()
    except subprocess.CalledProcessError as err:
        webquiz_error(True, f'Error with "kpsewhich {search}"', err=err)

[AndrewMathas]

I wonder, does the following python code return b'C:/Program Files/MiKTeX 2.9\r\n' ?

import subprocess
subprocess.check_output('kpsewhich -var-value=TEXMFMAIN', shell=True)

[daviddhtn]

It does not work, dear AndrewAtLarge

[AndrewMathas]

What you ran is slightly different to what I posted above: note the equals sign = between the -var-value and the TEXMFMAIN. I suspect that it won't work either, but I am curious.

Have you tried the changes above that I posted for the kpsewhich command in webquiz_util.py?

[daviddhtn]

It also does not work

    except subprocess.CalledProcessError as err:
        webquiz_error(True, f'Error with "kpsewhich {search}"', err=err)

and letting me know if this fixes the problem. Given this issue, I should change the other subprocessor calls that use shell-True as well.

It is late for me, so I will check tomorrow morning. It is funny that it works for me but I am grateful that you identified the problem. Thanks.

[daviddhtn]

Good morning AndrewAtLarge, I am sorry for replying late, I try to edit webquiz_util.py, install and then edit the line 41 in webquiz.py ini_file = os.path.join(webquiz_util.webquiz_file(''), '..', 'latex', 'webquiz.ini') to ini_file = os.path.join(webquiz_util.webquiz_file(''), '', 'latex', 'webquiz.ini') After finishing initialise, I test for a simple text file but receive this error. I am trying upgrade all packages of the Miktex and hope it works. Thanh you very much

I am very sorry for disturbing you again, I have installed on three computers (two with Texlive 2019 and another with MiKTeX 2.9.7380 64-bit, all are complete packages ) but can not compile a simple example

Here are error in compile and display web

[AndrewMathas]

You are getting the same error as before. This is what the The system cannot find the path specified. messages mean. I think that you cannot have replaced the definition of the kpsewhich function with the code that I posted above because if you had then the program would exit with an error rather than continuing. Please tell me what changes you made to my code as I honestly can't help if I don't know what you have done.

I am also confused as to why you said you changed the line

ini_file = os.path.join(webquiz_util.webquiz_file(''), '..', 'latex', 'webquiz.ini')

If webquiz is properly installed then this line of code never gets called. YOu only saw it because the kpsewhich command is still failing.

[daviddhtn]

Dear AndrewAtLarge Here is my experience, 1- For Windows 10 v.1903 (64bits) + and MiKTeX 2.9.7380 (64bits) + Python 3.7.2 (64bits) a- It does not work if webquiz is installed directly via miktex package manager

2. Uninstall webquiz package and install from the unzip file a- Cannot install with original file b- After editting line 34 in webquiz_util.py (as your suggestion), i can install ( webquiz.bat --tex-install) and initialize (webquiz -i), but cannot compile the tex file

   
   try:
       return subprocess.check_output(['kpsewhich']+search.split()).decode('ascii').strip()
   except subprocess.CalledProcessError as err:
       webquiz_error(True, f'Error with "kpsewhich {search}"', err=err)
   
   

   b1-Delete every folder related to webquiz, unzip the original webquiz.zip then copy to C:\Program Files\MiKTeX 2.9\scripts. It still cannot install (error as in case 2a) b2- Edit the webquiz_util.py as your suggestion, still error in
   

c- I try to edit some codes at %AppData%\Roaming\MiKTeX\2.9\scripts\webquiz Line 41 in webquiz.py in %AppData%\Roaming\MiKTeX\2.9\scripts\webquiz to ini_file = os.path.join(webquiz_util.webquiz_file(''), '', 'latex', 'webquiz.ini') Line 34 in webquiz_util.py as your suggestion Now, it got some error (may be not from your code but make4ht) 3- Test the output file I run local web server using XAMPP with PHP 7.4.4 It works well now, I'll post my experience in Texlive 2019 later, Thank you very much for your help,

[AndrewMathas]

David, in all of your output above you see many times The system cannot find the path specified These messages seem to be an error generated by the windows OS because it cannot find something in your system path. See for example https://superuser.com/questions/727316/error-in-command-line-the-system-cannot-find-the-path-specified. I wonder what command is missing from your path and what effect this is having.

I am unable to reproduce your errors and the syntax change for using subprocess.check_output does not make sense to me because all of the classes in the standard python libraries should work in the same way on all systems - and this code works for me on a windows machine.

This said, I don't use windows so the program is certainly not as well tested on this OS.
