It looks like you need to inspect `node_installed.stderr` instead of
`stdout`. The string you are looking for seems to go there instead.
ok: [localhost] => {
"changed": false,
"foo": {
"_ansible_no_log": false,
"changed": true,
"cmd": ". /Users/matt/.nvm/nvm.sh && nvm install v0.12.2",
"delta": "0:00:04.243197",
"end": "2015-10-16 09:41:08.582763",
"rc": 0,
"start": "2015-10-16 09:41:04.339566",
"stderr": "v0.12.2 is already installed.",
"stdout": "Now using node v0.12.2 (npm v2.7.4)",
"stdout_lines": [
"Now using node v0.12.2 (npm v2.7.4)"
],
"warnings": []
}
}
