FVM Installation Guide

Install on macOS and Linux

bash

curl -fsSL https://fvm.app/install.sh | bash

Note: The installer cannot modify your current shell PATH when run as a separate process (e.g., curl | bash). For CI or same-step usage, add:

bash

export PATH="$HOME/fvm/bin:$PATH"

bash

curl -fsSL https://fvm.app/install.sh | bash -s 3.2.1

For Docker, Podman, or CI environments:

bash

export FVM_ALLOW_ROOT=true
curl -fsSL https://fvm.app/install.sh | bash

For same-step usage, add:

bash

export PATH="$HOME/fvm/bin:$PATH"

For later steps, persist PATH using your CI's env file mechanism (e.g., $GITHUB_PATH on GitHub Actions, $BASH_ENV on CircleCI).

bash

curl -fsSL https://fvm.app/install.sh | bash -s -- --uninstall

bash

choco install fvm
