pipx-in-pipx (formerly pipipxx)

1.0.1 · maintenance · verified Fri Apr 17

pipx-in-pipx (pronounced 'pipx in pipx') is a utility designed to bootstrap pipx itself using pipx. It allows for running or installing pipx into an isolated pipx environment, primarily for ensuring a consistent pipx setup or installing specific pipx versions. The current version is 1.0.1, released in October 2019, indicating a stable but less actively developed codebase.

Common errors

```
ModuleNotFoundError: No module named 'pipx_in_pipx'
```
cause You are trying to import or reference the internal module using the PyPI package name `pipx-in-pipx` instead of its actual internal module name.

fix Use the internal module name `pipipxx`. For command-line execution, `pipx run pipipxx`. For Python imports, `import pipipxx`.
```
`pipipxx`: command not found
```
cause After `pip install pipx-in-pipx`, the `pipipxx` command isn't automatically added to your system PATH unless you use `pipx install`.

fix The recommended way to run this tool is via `pipx run pipipxx [arguments]`. If you want a persistent command, use `pipx install pipx-in-pipx`, and then `pipipxx` should be available in your pipx-managed PATH.
```
pipx is not installed.
```
cause The `pipx-in-pipx` tool itself requires `pipx` to be available on your system to run, as its purpose is to bootstrap or manage `pipx` installations.

fix First, ensure `pipx` is installed on your system using `python3 -m pip install --user pipx` (if not already installed) before attempting to use `pipx-in-pipx`.

Warnings

breaking The PyPI package is named `pipx-in-pipx`, but the internal Python module is named `pipipxx`. Attempting to `import pipx_in_pipx` or refer to `pipx-in-pipx` in `pipx run` will result in a `ModuleNotFoundError` or incorrect execution.
Fix: When running via `pipx run`, use `pipx run pipipxx`. If you need to import, use `import pipipxx`. Refer to the GitHub README for correct usage patterns.
gotcha This library is primarily a command-line tool designed to be executed via `pipx run pipipxx` or `pipx install pipx-in-pipx`. While it's a Python package, it's not typically intended for programmatic import and direct use as a library within other Python scripts.
Fix: For its intended purpose, prefer executing it from the command line using `pipx run pipipxx [args]`.
gotcha The last release (1.0.1) was in October 2019. While the core concept remains valid, it might not fully leverage or be aware of the very latest features, best practices, or minor behavioral changes in `pipx` itself since that time.
Fix: Review the official `pipx` documentation for recent changes if encountering unexpected behavior, and consider if this tool is still the most current or necessary approach for very new `pipx` versions. It might be sufficient to simply `pip install pipx` and then `pipx install` other tools.

Install

pip install pipx-in-pipx Install into current environment

Imports

pipipxx
wrong:
```
import pipx_in_pipx
```
correct:
```
import pipipxx
```
Despite the PyPI package name `pipx-in-pipx`, the internal Python module is named `pipipxx`. This library is primarily designed to be run as a command-line tool via `pipx run pipipxx` rather than imported programmatically.

Quickstart

This command uses `pipx run` to execute the `pipipxx` module (which is `pipx-in-pipx`), which in turn installs a specific version of `pipx` (e.g., 1.2.0) into its own isolated pipx environment. This is the primary use case for managing pipx versions or ensuring a clean pipx setup.

pipx run pipipxx -- install --spec 'pipx==1.2.0'
