Problem

Multiple commands are needed to do a one-shot install without leaving behind an extra copy in the cache folder. This came up in context of docker container setup.

See: #809

Solution

Add --cleanup which will delete cached version after install.

% n install --cleanup 20.0.0
  installing : node-v20.0.0
       mkdir : /usr/local/n/versions/node/20.0.0
       fetch : https://nodejs.org/dist/v20.0.0/node-v20.0.0-darwin-arm64.tar.xz
     copying : node/20.0.0
   installed : v20.0.0 (with npm 9.6.4)
     cleanup : removing cached node/20.0.0
