vue项目怎么查看node版本?

如果项目使用的 yarn 和 typescript，可以查看yarn.lock 里的@types/node@ 的 version:

package-lock.json:

"@types/node": {
      "version": "12.12.7",
      "resolved": "https://registry.npm.taobao.org/@types/node/download/@types/node-12.12.7.tgz?cache=0&other_urls=https%3A%2F%2Fregistry.npm.taobao.org%2F%40types%2Fnode%2Fdownload%2F%40types%2Fnode-12.12.7.tgz",
      "integrity": "sha1-AeTqck2eO9UNkMEf1ZgLoxfY+hE=",
      "dev": true
    },
