What's Wrong?

Claude is not able to run npm run test:run it says:

Found it — Node 18.19.1 but Vitest 4 requires Node 20+. The package.json even says "engines": { "node": ">=20 <=23" }.

nvm has Node 22.13.1 installed but the shell is using Node 18.19.1 (the system version). The default is set to 22, so why is node --version showing v18?

Let me check what's happening. The make test runs npm run test:run which uses the system Node (not the nvm-managed one). The current shell has Node 18 as the system default.

Actually wait, looking at the nvm output: ->     v22.13.1 * and system * - the -> indicates the current shell is using v22.13.1, and system * also has the asterisk.

But node --version is returning v18.19.1, which suggests the Bash tool isn't sourcing nvm's initialization script, so it's falling back to the system Node in the PATH. I should try sourcing nvm before running vitest to ensure it uses the correct version.

What Should Happen?

It must use the system Node version
