when i did go from Node 16.2 to 1.6.6 it did do the update to that version
(this is with npm just included, not an extra npm install)

but then weird npm-cli errors came up
when i then really just first delete the "node" dir and let the plugin install node again everything was fine

if i look into:

https://github.com/eirslett/frontend-maven-plugin/blob/master/frontend-plugin-core/src/main/java/com/github/eirslett/maven/plugins/frontend/lib/NodeInstaller.java

i also don't really see a full delete first..

NpmInstaller i do see that that it first does delete stuff.
But not when npm is provided by node i think it is this code:

https://github.com/eirslett/frontend-maven-plugin/blob/master/frontend-plugin-core/src/main/java/com/github/eirslett/maven/plugins/frontend/lib/NodeInstaller.java#L189

are we needing there 1 line of code that deletes first if it is there the full target dir?
