I was looking for a solution for the nvm prefix problem a found this question(before finding the solution). Here is my shell "dialog". I hope, it can be usefull for somebody. I was able to set to prefix with the help of this post: https://github.com/npm/npm/issues/6592

When I tried npm config delete prefix or nvm use --delete-prefix before using npm --prefix="" set prefix "", I got only: npm ERR! not ok code 0

Note that you will have to repeat the same procedure with every node version, the prefix is set back to (in my case) /usr/local after installation.

    $ nvm install 0.10

    nvm is not compatible with the npm config "prefix" option: currently set to "/usr/local"
    Run `npm config delete prefix` or `nvm use --delete-prefix v0.10.44` to unset it.
    $ npm --prefix="" set prefix ""
    $ nvm use 0.10.44
    nvm is not compatible with the npm config "prefix" option: currently set to "/home/john"
    Run `npm config delete prefix` or `nvm use --delete-prefix v0.10.44` to unset it.
    $ nvm use --delete-prefix v0.10.44
    Now using node v0.10.44 (npm v1.3.10)
    $ nvm ls
    v0.10.44
             v4.4.3
    ->       system
    default -> 4.4.3 (-> v4.4.3)
    node -> stable (-> v4.4.3) (default)
    stable -> 4.4 (-> v4.4.3) (default)
    iojs -> N/A (default)
    $ npm config get prefix
    /usr/local
