nvs rm <version>
nvs remove <version>
Removes a node version that was previously added via an ADD command. Any symlinks or PATH entries (in the calling shell environment only) pointing to that version are also removed.
A version string consists of a semantic version number, optionally preceded by a remote name, optionally followed by a processor architecture or bitness ("x86", "x64", "32", "64"), separated by slashes. Examples: "4.6.0", "6/x86", "node/6.7/x64"
A remote name is one of the keys from the remotes mapping in $NVS_HOME/settings.json.
