Clone only the latest branch:

git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.7.4

Alternately, you can clone the whole repo and checkout the latest branch:

git clone https://github.com/asdf-vm/asdf.git ~/.asdf
cd ~/.asdf
git checkout "$(git describe --abbrev=0 --tags)"

Install using the Homebrew package manager on macOS:

brew install asdf

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc

Installation via Git:

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bash_profile
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bash_profile

Installation via Homebrew:

?> If you have Homebrew's Bash completions configured, the second line below is unnecessary. See Configuring Completions in Bash in the Homebrew docs.

echo -e "\n. $(brew --prefix asdf)/asdf.sh" >> ~/.bash_profile
echo -e "\n. $(brew --prefix asdf)/etc/bash_completion.d/asdf.bash" >> ~/.bash_profile

If you are using a framework, such as oh-my-zsh, use these lines. (Be sure that if you make future changes to .zshrc these lines remain below the line where you source your framework.)

Installation via Git:

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.zshrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.zshrc

Installation via Homebrew:

?> If you have Homebrew's ZSH completions configured, the second line below is unnecessary. See Configuring Completions in ZSH in the Homebrew docs.

echo -e "\n. $(brew --prefix asdf)/asdf.sh" >> ~/.zshrc
echo -e "\n. $(brew --prefix asdf)/etc/bash_completion.d/asdf.bash" >> ~/.zshrc

If you are not using a framework, or if on starting your shell you get an error message like 'command not found: compinit', then add this line before the ones above.

autoload -Uz compinit && compinit

Installation via Git:

echo 'source ~/.asdf/asdf.fish' >> ~/.config/fish/config.fish
mkdir -p ~/.config/fish/completions; and cp ~/.asdf/completions/asdf.fish ~/.config/fish/completions

Installation via Homebrew:

?> Homebrew takes care of installing the completions for fish shell. Friendly!

echo "source "(brew --prefix asdf)"/asdf.fish" >> ~/.config/fish/config.fish

Restart your shell so that PATH changes take effect. (Opening a new terminal tab will usually do it.)

!> If you're having issues with it not detecting the shims you've installed it's most-likely due to the sourcing of above asdf.bash or asdf.fish not being at the BOTTOM of your ~/.bash_profile, ~/.zshrc, or ~/.config/fish/config.fish. It needs to be sourced AFTER you have set your $PATH.

?> For most plugins, it is good if you have installed the following packages OR their equivalent on your OS

Installation via Homebrew:

brew install \
  coreutils automake autoconf openssl \
  libyaml readline libxslt libtool unixodbc \
  unzip curl

Installation via Spack:

spack install \
  coreutils automake autoconf openssl \
  libyaml readline libxslt libtool unixodbc \
  unzip curl

sudo apt install \
  automake autoconf libreadline-dev \
  libncurses-dev libssl-dev libyaml-dev \
  libxslt-dev libffi-dev libtool unixodbc-dev \
  unzip curl

sudo dnf install \
  automake autoconf readline-devel \
  ncurses-devel openssl-devel libyaml-devel \
  libxslt-devel libffi-devel libtool unixODBC-devel \
  unzip curl

That's all! You are ready to use asdf 🎉

?> If you're migrating from other tools and want to use your existing .node-version or .ruby-version version files, look at the legacy_version_file flag in the configuration section.

asdf update

If you want the latest changes that aren't yet included in a stable release:

asdf update --head

brew upgrade asdf

Uninstalling asdf is as simple as:

1. In your .bashrc (or .bash_profile if you are on OSX) or .zshrc find the lines that source asdf.sh and the autocompletions. The lines should look something like this:

   . $HOME/.asdf/asdf.sh
   . $HOME/.asdf/completions/asdf.bash

   Remove these lines and save the file.

2. Run rm -rf ~/.asdf/ ~/.tool-versions to completely remove all the asdf files from your system.

3. (Optional) If you installed asdf using a package manager, you may want to use that package manager to uninstall the core asdf files.

That's it! 🎉
