Trust, Then Verify
An install is not done until you prove it works. The fastest proof is asking Mojo to report its own version. ✅
The Version Command
Inside your activated project, run mojo with the --version flag. A clean version string means the compiler is reachable.
mojo --versionReading the Output
The output names the language and a version number like 24.x. That number tells you exactly which release you are on.
mojo 24.4.0 (abc123)Why Versions Matter
Mojo is young and evolving fast. Knowing your version helps you match tutorials and report issues that actually apply to you.
Check Without the Shell
Not in a magic shell? Run it through the project manager instead, so the right toolchain answers with magic run.
magic run mojo --versionCheck the CLI Too
You can also confirm the manager itself. Asking magic for its version separates a CLI problem from a Mojo problem.
magic --versionWhen mojo Is Not Found
A not-found error usually means you are outside the project. Run magic shell first, or prefix the command with magic run.
Keeping Mojo Updated
New releases land often. Refresh your project's packages with magic update to move to the latest compatible Mojo.
magic updateSee What Is Installed
Curious about every dependency? magic list shows the packages and exact versions your project currently pins.
magic listNote It for Later
Jot down your version when following a guide. If something behaves oddly, that version number is the first clue to share.
Try a Nightly Build
Want the newest features early? Modular offers a nightly channel, though those builds change fast and can be less stable.
Quick Check
Recall the flag that makes Mojo print which release you have installed.
Recap
You verified the install with mojo --version, learned to read the number, and can refresh it with magic update. Confirmed! 🎯
