Then execute:\n\n```sh\ncurl -fsSL https://fnm.vercel.app/install | bash\n```\n\n#### Upgrade\n\nOn macOS, it is as simple as `brew upgrade fnm`.\n\nOn other operating systems, upgrading `fnm` is almost the same as installing it. To prevent duplication in your shell config file, pass `--skip-shell` to the install command:\n\n```sh\ncurl -fsSL https://fnm.vercel.app/install | bash -s -- --skip-shell\n```\n\n#### Parameters\n\n`--install-dir`\n\nSet a custom directory for fnm to be installed. The default is `$XDG_DATA_HOME/fnm` (if `$XDG_DATA_HOME` is not defined it falls back to `$HOME/.local/share/fnm` on linux and `$HOME/Library/Application Support/fnm` on MacOS).\n\n\u003e **Note:** On macOS, this option is only meaningful when using `--force-install` since Homebrew is the default installation method.\n\n`--skip-shell`\n\nSkip appending shell specific loader to shell config file, based on the current user shell, defined in `$SHELL`. e.g. for Bash, `$HOME/.bashrc`. `$HOME/.zshrc` for Zsh. For Fish - `$HOME/.config/fish/conf.d/fnm.fish`\n\n`--force-install`\n\nmacOS",

  "why_use_this": "fnm is a drop-in replacement for nvm that starts instantly and manages multiple Node.js versions with minimal overhead. Built in Rust for speed and distributed as a single binary, it reads standard .node-version/.nvmrc files and works across macOS, Windows, and Linux without shell-specific complications."
