Using Inko's version manager

Inko has its own version manager: ivm. Using ivm you can install and manage multiple versions of Inko. ivm is written in Rust.


ivm itself only requires Rust 1.68 or newer, but to build Inko itself you'll need to also meet the requirements listed in the installation guide.


Arch Linux

ivm can be installed using the AUR using an AUR wrapper of your choice. For example, using yay:

yay -S ivm

Or manually:

git clone
cd ivm
makepkg -si

From source

Clone the repository:

git clone
cd ivm
cargo build --release

The resulting executable is found in target/release/ivm.



If a package is available for your platform, we recommend installing ivm through your platform's package manager instead. Once ivm is available on enough platforms, we may stop publishing it to

ivm is available on, and you can install it as follows:

cargo install ivm

This installs the ivm executable in $HOME/.cargo/bin, where $HOME is your home directory. You need to add this to your shell's PATH if not done already:

export PATH="$HOME/.cargo/bin:$PATH"
fish_add_path --path $HOME/.cargo/bin

For more information, refer to this rustup documentation page.

To update ivm, run the following:

cargo install ivm --force

Setting up your PATH

Once ivm is installed, you need to add its bin path to your PATH variable. This is needed to ensure that executables such as inko are available. To add the path, run ivm show bin, then add the path it prints out to your PATH variable. For example:

$ ivm show bin

Assuming you're using Bash as your shell, you'd add the following to your .bashrc:

export PATH="$HOME/.local/share/ivm/bin:$PATH"


To install a version (e.g. 0.10.0):

ivm install 0.10.0    # This will install version 0.10.0
ivm install latest    # This will install the latest available version


Make sure to set a default version after installing Inko, otherwise you have to use ivm run VERSION inko ... to use Inko.

To remove a version:

ivm remove 0.10.0    # This will remove version 0.10.0
ivm remove latest    # This will remove the latest _installed_ version

To list all installed versions:

ivm list

To list all available versions:

ivm known

To change the default Inko version:

ivm default 0.10.0

To remove any temporary data:

ivm clean

To run a command with a specific Inko version:

ivm run 0.10.0 inko --version # This will run `inko --version` using Inko 0.10.0
ivm run latest inko

To remove all data of ivm (except the ivm executable itself):

ivm implode

For more information, run ivm --help.

Setting a default version

The default command is used to set a default Inko version to use. When set, ivm will create a symbolic link in its bin/ directory to the inko executable of the default version. By setting a default version you can just use inko ... instead of the much more verbose ivm run VERSION inko ....

Packaging ivm

If you are building a package of ivm (e.g. for Debian), you can use the provided Makefile instead of cargo build:

make install

This process can be customised by setting the following Make variables:

  • DESTDIR: the directory to install files into when running make install.
  • PREFIX: the path prefix to use for all files, defaults to /usr. When combined with DESTDIR, the value of DESTDIR prefixes this value.
