# tooling comparison

Taken from stackoverflow answer from nvm maintainer

The most-used version managers for node are without a doubt http://nvm.sh, https://www.npmjs.com/package/nave, and https://www.npmjs.com/package/n.

nvm is for modifying individual shell sessions to use the version you want. nave is for launching subshells with the version you want loaded. n is for switching a single system-wide version of node.

nvm uses a .nvmrc file, which like .ruby-version, contains the version-ish string X you'd normally couple with nvm use X or nvm install X. nvm use or nvm install by itself will locate the .nvmrc file, as will simply sourcing nvm upon opening a new shell.

It appears nave supports a .naverc file, but I'm not too familiar with its usage.

n doesn't appear to support any such config, but as it's system-wide, it doesn't really make as much sense to do so.

avn supports .node-version and attempts to provide automatic version switching by hooking into cd, after nvm decided that was too invasive a behavior to include.

Node.js version management: no subshells, no profile setup, no convoluted API, just simple.

# usage

Super easy but system wide.

List installed version

Output :

  0.8.14
ο 0.8.17
  0.9.6

Change the active version by selecting the line and hit space bar.

Install desired node version with n <version> ex n 10.2.1.

# issues

Possible issue with npm, any npm command will output this :

npm WARN lifecycle npm is using /home/&lt;HOME_DIR>/n/bin/node but there is no node binary in the current PATH. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.

Fixed by adding a .npmrc file in the project root dir containing :

scripts-prepend-node-path=true
