pipx fails to run script with dependencies.

[planetmarshall]

Describe the bug

According to the docs, the following script should run:

# test.py

# Requirements:
# requests
#
# The list of requirements is terminated by a blank line or an empty comment line.

import sys
import requests
project = sys.argv[1]
pipx_data = requests.get(f"https://pypi.org/pypi/{project}/json").json()
print(pipx_data["info"]["version"])

How to reproduce

brew install pipx
pipx ensurepath
pipx run test.py

Expected behavior

ths script should install the requirements and output the pipx version (eg. 1.4.3)

Actual Behaviour

output is

File "/Users/andrew/projects/pipx-test/test.py", line 9, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

Notes

• pipx version 1.4.3
• Macos Ventura 13.6.2 (arm64)
• Python 3.12 (homebrew)

This runs normally in my Debian installation. Could you post the output of pipx run with --verbose?

[planetmarshall]

In the tests the syntax for this feature is different - it's

# test.py

# /// script
# dependencies = ["requests"]
# ///

import sys
import requests
project = sys.argv[1]
pipx_data = requests.get(f"https://pypi.org/pypi/{project}/json").json()
print(pipx_data["info"]["version"])

Which works - maybe it's the docs that need updating?

Right, I forgot – When implementing support for inline script metadata, we also removed support for the old requirement specification. A pull request to update the section would be welcome.
