npm_config_prefix default shouldn't be a relative path

[louim]

Hello!
#28 added a default npm_config_prefix of ~/.npm-global, and this path is added to the global path (for all users). So for all other user except the ansible_ssh_user, this path will not resolve because it will be expanded as their home folder.

I think a better default would be something like: /usr/local/lib/npm, so the path will resolve for all users.

What do you think?

@louim yeah I agree that's a saner default for this role.

I was using the context of a VM provisioned with a single non admin user whereas this role can be used elsewhere in a multi user environment.

Just need to override this variable in the default config of Drupal VM to avoid introducing a regression geerlingguy/drupal-vm#629

I was just trying to get something similar working, with the latest version of Drupal VM. Here's the config I was trying to use in the config.yml:

# `nodejs` must be in installed_extras for this to work. Valid examples: "0.10",
# "0.12", "4.x", "5.x".
nodejs_version: "4.x"

nodejs_npm_global_packages: 
  - name: gulp
  - name: browser-sync
  - name: avn
  - name: avn-nvm

nodejs_install_npm_user: "vagrant"
npm_config_prefix: "~/.npm-global"
npm_config_unsafe_perm: "true"

I have also tried it without that last variable, and with the alternate option of npm_config_prefix: "/usr/local/lib/npm"

The install for global packages just keeps failing. I will try to attach npm-debug.log as well, if that will be of any use.
npm-debug.log.txt

@sarahjean are you sure you are running the latest version of the role? The log make it look like it is trying to write to /usr/lib/node_modules/avn-nvm.

[sarahjean]

Not the latest, do I need to be on 3.1.0 for this? The latest tagged version of drupal-vm is running this

- src: geerlingguy.nodejs
  version: 3.0.0

[louim]

Yep: 3.0.0...3.1.0

[sarahjean]

@lulm, Ok, bumped the version and it worked beautifully.

[geerlingguy]

Fixed via #31

[geerlingguy]

This will be in 3.2.0 (and I'll have Drupal VM use that role version for it's 3.1.1 release).
