# Package Manager Reference

|
## Homebrew
|
|
|
|
### Update workflow
|
|
```bash
|
|
brew update # Update Homebrew itself and formulae list
|
|
brew outdated # List outdated formulae
|
|
brew outdated --cask # List outdated casks
|
|
brew upgrade # Upgrade all outdated formulae
|
|
brew upgrade <name> # Upgrade specific formula
|
|
brew upgrade --cask # Upgrade all casks
|
|
brew cleanup --prune=0 # Remove all cached downloads
|
|
brew autoremove # Remove orphaned dependencies
|
|
brew doctor # Diagnose issues
|
|
```
|
|
|
|
### Safety notes
|
|
- `brew upgrade` is generally safe but can break projects pinned to specific versions
|
|
- Always check `brew doctor` warnings — some are cosmetic, some indicate real issues
|
|
- `brew autoremove` only removes packages not depended on by anything
|
|
|
|
## npm / nvm
|
|
|
|
### Update workflow
|
|
```bash
|
|
nvm ls # List installed Node versions
|
|
nvm install --lts # Install latest LTS
|
|
npm outdated -g # Check global packages
|
|
npm update -g # Update all global packages
|
|
npm cache clean --force # Clear npm cache
|
|
```
|
|
|
|
### Safety notes
|
|
- Global npm packages are version-independent from project dependencies
|
|
- Updating global packages won't affect project-level node_modules
|
|
|
|
## Python / pyenv
|
|
|
|
### Update workflow
|
|
```bash
|
|
pyenv versions # List installed versions
|
|
pyenv install --list # Available versions
|
|
pip list --outdated # Outdated packages in current env
|
|
pip install --upgrade <pkg> # Upgrade specific package
|
|
pip cache purge # Clear pip cache
|
|
```
|
|
|
|
### Safety notes
|
|
- Only audit pyenv-managed environments (not system Python)
|
|
- pip upgrades can break dependency chains — suggest `--dry-run` first
|
|
- Virtual environments in project directories are not scanned (out of scope v1)
