Local download directory

[zxiiro]

When running nodeenv -p it always redownloads the node package. I was wondering if there was a way to cache node locally and pass a parameter so that nodeenv -p will downloaded from a local repo instead?

Checked this against current master, both halves of the request are covered.

"nodeenv -p always redownloads node" - no longer the case since #403: a repeated -p with the same version prints Node.js X is already installed, skipping (use --force to reinstall) and downloads nothing.

"a parameter to install from a local repo" - this works today through --mirror, which takes a full URL (#252), including file://:

$ nodeenv --node=22.14.0 --mirror=file:///srv/node-mirror env-22

The directory only has to repeat the nodejs.org layout: packages in v<version>/, plus an index.json next to them if you want latest, lts or a version range to resolve. It can be set once in ~/.nodeenvrc as mirror = file:///srv/node-mirror.

That was undocumented, so #405 adds it to the README with a test. This issue closes when that lands.

What still does not exist is an automatic shared cache between environments: each environment downloads into its own <env>/src, which is now removed after the install by default (#404). If that is what you need, it is worth a separate issue for a --cache-dir-style option.

The shared cache part is now tracked separately in #406.
