Install script Django - Missing command python

Submitted by DzintarsSeglins on Tue, 01/19/2021 - 03:14 Pro Licensee

I buy Virtulamin 6.14 Pro version for running Django.

Tried to install on virtual serveris with Available Scripts -> Django 1.9.7 and I get this error message.

This script cannot be installed, as this virtual server does not meet its requirements : The python command is not installed, Could not work out Python version : sh: 1: --version: not found , Missing command python

Tried to google this problem but at the moment without any luck.

Status: 
Fixed (pending)
Virtualmin version: 
6.14
Webmin version: 
1.962

Hi,

The simple work-around would be is to go to Virtualmin Configuration and set default Python command to python3 in Advanced Options.

Next Virtualmin release will have it working the right way out of the box.

Thanks for reporting.

When I start to install script then get this error:

Reading package lists...
Building dependency tree...
Reading state information...
Package python-mysqldb is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python-mysqldb' has no installation candidate

I fix with

sudo apt-get install python3-mysqldb

but then:

Now installing Django version 1.9.7 ..

Okay, there were few bugs. It will be fixed for the next release, meanwhile run:

curl https://raw.githubusercontent.com/virtualmin/virtualmin-gpl/master/scripts-lib.pl -o /usr/share/webmin/virtual-server/scripts-lib.pl

.. and you would need to update Django install script and make sure that you're installing latest 3.1.5 which actually works:

curl https://raw.githubusercontent.com/virtualmin/virtualmin-gpl/master/scripts/django.pl -o /usr/share/webmin/virtual-server/scripts/django.pl

Restart Webmin afterwards and enjoy your ride. :--)

/etc/webmin/restart

I ran into the same problem and after following the above directions I encountered another problem:

FIELD_TYPE.JSON: 'JSONField', AttributeError: module 'MySQLdb.constants.FIELD_TYPE' has no attribute 'JSON'

It doesn't seem as Virtualmin issue to me.

I won't ask why you're still using Django 1.9 but I noticed that in your posts you have:

"Now installing Django version 1.9.7"

"python/Django-1.9.7-py3.8.egg"

"python/Django-3.1.7-py3.7.egg"

You can't mix and match Django ~ python versions. I recommend using "virtualenv" to compartmentalise your packages.

FWIW you shouldnt be putting your Django app inside "public_html". One bad config and Apache will be returning your whole file directory to the browser.
