Change effective on 25 April 2014
The Node.js buildpack’s vendored
npm binaries are now prepended to the
PATH (instead of appended), giving them precedence over any locally-installed
npm binaries in your development environment. This change was made to improve the buildpack testing process and will have no impact on running apps.
For more information about node binaries and
PATH, see the Node.js Support article on Dev Center.
