Demo

The following demo shows:

• how to use mise exec to run a command with a specific version of a tool
• how you can use mise to install and many other tools such as jq, terraform, or go.
• how to use mise to manage multiple versions of node on the same system.

Transcript

mise exec <tool> -- <command> allows you to run any tools with mise

mise exec node@22 -- node -v
# mise node@22.14.0 ✓ installed
# v22.14.0

node is only available in the mise environment, not globally

node -v
# bash: node: command not found

---

Here is another example where we run terraform with mise exec

mise exec terraform -- terraform -v
# mise terraform@1.11.3 ✓ installed
# Terraform v1.11.3

---

mise exec is great for running one-off commands, however it can be convenient to activate mise. When activated, mise will automatically update your PATH to include the tools you have installed, making them available directly.

We will start by installing node@lts and make it the global default

mise use --global node@lts
# v22.14.0

node -v
# v22.14.0

which node
# /root/.local/share/mise/installs/node/22.14.0/bin/node

Note that we get back the path to the real node here, not a shim.

---

We can also install other tools with mise. For example, we will install terraform, jq, and go

mise use -g terraform jq go
# mise jq@1.7.1 ✓ installed
# mise terraform@1.11.3 ✓ installed
# mise go@1.24.1 ✓ installed
# mise ~/.config/mise/config.toml tools: go@1.24.1, jq@1.7.1, terraform@1.11.3

terraform -v
# Terraform v1.11.3

jq --version
# jq-1.7

go version
# go version go1.24.1 linux/amd64

mise ls
# Tool       Version  Source                      Requested
# go         1.24.1   ~/.config/mise/config.toml  latest
# jq         1.7.1    ~/.config/mise/config.toml  latest
# node       22.14.0  ~/.config/mise/config.toml  lts
# terraform  1.11.3   ~/.config/mise/config.toml  latest

---

Let's enter a project directory where we will set up node@23

cd myproj
mise use node@23 pnpm@10
# mise node@23.10.0 ✓ installed
# mise pnpm@10.7.0 ✓ installed

node -v
# v23.10.0
pnpm -v
# 10.7.0

As expected, node -v is now v23.x

cat mise.toml
# [tools]
# node = "23"
# pnpm = "10"

We will leave this directory. The node version will revert to the global LTS version

cd ..
node -v
# v22.14.0
