Version

3.0.0-rc.3

Reproduction link

https://unpkg.com/@vue/cli@3.0.0-rc.3/lib/util/

Steps to reproduce

• npm install -g @vue/cli
• browse to global @vue/cli npm folder (on Windows \Users\{username}\AppData\Roaming\npm\node_modules\@vue\cli\lib\util)
• open the .version file, it contains 3.0.0-beta.15

What is expected?

I assume the file should contain 3.0.0-rc.3 (or whatever happens to be the latest version). And that when creating a new app, the package devDependencies should be from the latest version. However, they are using the value from the .version file, e.g. 3.0.0-beta.15.

What is actually happening?

Looking at the @vue/cli/lib/util/getVersions.js file (https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli/lib/util/getVersions.js), the code appears to use that file as a version cache if the file hasn't been modified within the past 7 days.

I suspect perhaps the version number in the .version file was a result of a bad package? If not, then the getVersions.js code should compare the cached version against the latest version. I'll be submitting a PR with a change to check the cached version.
