perhaps conider using pad-left instead. it's not having issues on npm and it's orders of magnitude faster because it uses repeat-string

[michaelficarra]

It's a bad idea to use ^ and 0.x together.

[taion]

I'd amend @michaelficarra's point to say that using ^0.0.9 makes no sense, since that only matches 0.0.9 exactly.

It'd make the most sense to use a version that actually has correct semver semantics, or else switch to the faster pad-left entirely, per @doowb.
