Inko's version manager
Inko has its own version manager called ivm. Using ivm you can install and manage multiple versions of Inko; whether you are using Linux, macOS, or Windows. ivm is written in Rust and does not come with system dependencies of its own.
ivm works on Linux, macOS, and Windows. It probably also works on the various BSDs, but we haven't tested this. For all platforms a 64-bits architecture is required.
Both ivm and Inko require that you have Rust and cargo installed. We recommend that you install Rust and cargo using rustup. Once installed, you can install ivm by running the following:
cargo install ivm
This will install the
ivm executable in
your home directory (
%USERPROFILE% on Windows). You need to add this to your
shell's PATH if not done already. You also need to add the directory containing
Inko executables to your path:
set -x PATH $HOME/.cargo/bin $HOME/.local/share/ivm/bin $PATH
setx PATH "%USERPROFILE%\.cargo\bin;%LocalAppData%\ivm\bin;%PATH%"
When using Windows, you need to restart your terminal after running the
setx command, as it doesn't affect your current terminal.
You can then install ivm by running the following command:
cargo install ivm
To test if the installation was successful, run the following:
This should print a message like "ivm version XXX" where "XXX" is the current version of ivm.
To update ivm, run the following:
cargo install ivm --force
To install a version (e.g. 0.8.1):
ivm install 0.8.1 # This will install version 0.8.1 ivm install latest # This will install the latest available version
Make sure to set a default version after installing Inko, otherwise you have
ivm run VERSION inko ... to use Inko.
To uninstall a version:
ivm uninstall 0.8.1 # This will uninstall version 0.8.1 ivm uninstall latest # This will uninstall the latest _installed_ version
To list all installed versions:
To list all available versions:
To change the default Inko version:
ivm default 0.8.1
To remove any temporary data:
To run a command with a specific Inko version:
ivm run 0.8.1 inko --version # This will run `inko --version` using Inko 0.8.1 ivm run latest inko
To remove all data of ivm (except the ivm executable itself):

Setting a default version
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
of the default version. By setting a default version you can just use
instead of the much more verbose
ivm run VERSION inko ....
For this to work the
bin directory must be in your path, as covered in the
installation instructions. If you aren't sure where that directory is located,
run the following:
ivm show bin
This will print the path to the
bin directory, which you can then add to your
