System cannot identify installed Python packages

Any package installed through pip3 is declared to be 'successfully installed' but cannot be identified despite the path being included in the the $PATH environment variable.

So far have attempted the following:

• reinstalled Python
• Reset $PATH and manually added pip3 packages directory, found using pip3 list -v
• installing packages within a venv.

The issue is demonstrated below in the project directory antons_pizza on macOS Ventura 13.4 with zsh shell.

➜ echo $PATH                            
/usr/local/lib/python3.11/site-packages:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages:/Library/Frameworks/Python.framework/Versions/3.11/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin

➜  antons_pizza pip3 show django

• First of all make sure that it has executable permissions:

ls -l /usr/local/lib/python3.11/site-packages

• Now, the problem is when you execute some program with sudo it does not load a login shell environment before executing the command, so the default PATH from /etc/sudoers is used, and we get a command not found error.

• Solution:

1. open the sudoers file and add uncomment the secure_path variable and add your path in it.

sudo visudo

2. Find this line and uncomment it and add your path to it.

Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

3. Then re-login, and now try to call Django with sudo.

> You can also use this temporary solution:

sudo -E env "PATH=$PATH" your_command

Answered in the comments by @FlyingTeller, alas it was a simple typo.

I was trying to run django admin when the command is in fact django-admin.
