[SOLVED] mkdir command not found with Python 3 on Debian

Issue

I'm sure this is something simple, but I'm trying several settings and I just can't seem to get this to work.

I have the following code:

import subprocess

p = subprocess.Popen('mkdir -p /backups/my_folder', stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)

This is running in a flask application on nginx and python 3

When this executes I'm getting the following error:

/bin/sh: 1: mkdir: not found

I've tried with shell=False, I've tried with Popen(['mkdir', ...]), and I've tried subprocess.run like this question/answer

If I run with shell=False, I get the following error:

Error: [Errno 2] No such file or directory: 'mkdir -p /backups/my_folder': 'mkdir -p /backups/my_folder'

When I do /bin/mkdir, it works. But, there are other commands which call sub commands that fail (tar calling gz for instance)

What am I missing to get this to work?

Running:

Debian 9.8, Nginx 1.14.0, Python 3.6.8

EDIT

I need this to work for other commands as well. I know I can use os.makedirs, but I have several different commands I will be executing (rsync, ssh, tar, and more)

Solution

I found the problem.

I realized that my /etc/systemd/system/site.service uWSGI settings had a hard coded path:

Environment = /usr/local/bin

Once, I changed this to include /bin, all my subprocess commands executed just fine.
