Mojo Build Package Skill

Build compiled Mojo packages for distribution and reuse.

When to Use

  • Creating distributable libraries
  • Packaging phase of development
  • Preparing for package installation
  • Building modular components

Quick Reference

# Build single package
mojo package src/tensor -o packages/tensor.mojopkg

# Build and test
./scripts/build_package.sh tensor --test

# Build all packages
./scripts/build_all_packages.sh

Workflow

  1. Verify structure - Check __init__.mojo exists
  2. Build package - Run mojo package or script
  3. Test imports - Verify package can be imported
  4. Verify exports - Check __all__ in __init__.mojo

Mojo-Specific Notes

  • Every package needs __init__.mojo entry point
  • Export public API in __all__ list
  • Packages compile to .mojopkg binary format
  • No circular dependencies allowed

Error Handling

Error Cause Solution
Missing __init__.mojo No package entry point Add __init__.mojo to package dir
Circular dependency Modules depend on each other Refactor to break cycle
Export not found Missing from __all__ Add name to __all__ list
Build failed Syntax errors in module Fix syntax before building
