You're using dmd 2.066 which removed the module.
That went unnoticed with vibe.d because it wasn't previously possible to deprecate importing a module.
We've fixed this since then and will add std.metastrings back in 2.066.1.

The import is already removed in vibe.d's master and
you can use "vibe-d": ">=0.7.21-rc.2" in the meantime.

Thank you, it works...
