Description

The cactus build command fails when the repository is cloned into a directory path containing spaces (e.g., /Users/name/Programming Projects/cactus).

Error

/bin/sh: /Users/name/Programming: No such file or directory
Build failed

Root Cause

The run_command() function in python/src/cli.py passes string paths directly to subprocess.run() with shell=True, causing the shell to interpret spaces as argument separators.

Environment

• macOS (also likely affects Linux/Windows)
• Any path with spaces in the directory name

Steps to Reproduce

1. Clone the cactus repo into a path with spaces:

   cd "/Users/name/Programming Projects"
   git clone https://github.com/cactus-compute/cactus

2. Run setup and build:

   cd cactus && source ./setup && cd ..
   cactus build --python

3. Observe the error

Suggested Fix

Use shell=False with a list argument instead of shell=True with a string. This avoids shell interpretation entirely and handles paths with spaces correctly.
