Debug

Known issues

breakingVersion 2.x broke compatibility: the `run()` method changed from returning a tuple to an object; use `.run()` with explicit capture.

fix

Upgrade to >=3.0.0 and ensure you access stdout/stderr as returned tuple.

affects: < 3.0.0

gotchaThe `run()` method blocks until process finishes; do not use with long-running processes if you need real-time output.

fix

Use `start()` and iterate over `stdout_lines()` for streaming.

affects: all

gotchaRunning on non-POSIX or unsupported platforms may raise ImportError because of Rust binary dependency.

fix

Ensure you are on a supported platform (Linux x86_64, macOS x86_64/arm64, Windows x86_64).

affects: all

AttributeError: 'RunningProcess' object has no attribute 'run'

The class does not have a `run` method in older versions.

fix

Upgrade to version >=3.0.0: `pip install --upgrade running-process`.

OSError: [WinError 1920] The file cannot be accessed by the system

Windows antivirus or permission issue blocking the Rust binary.
