nodenv-npm-migrate is a nodenv plugin
that provides a nodenv migrate command to migrate npm packages from one Node
version to another.
This plugin was forked from pyenv-pip-migrate.
Installing nodenv-npm-migrate as a nodenv plugin will give you access to the
nodenv migrate command.
$ git clone git@github.com:nodenv/nodenv-npm-migrate.git "$(nodenv root)/plugins/nodenv-npm-migrate"
This will install the latest development version of nodenv-npm-migrate into
the $(nodenv root)/plugins/nodenv-npm-migrate directory. From that directory, you
can check out a specific release tag. To update nodenv-npm-migrate, run git pull to download the latest changes.
Mac OS X users can install nodenv-npm-migrate with the
Homebrew package manager.
This will give you access to the nodenv-migrate command. If you have nodenv
installed, you will also be able to use the nodenv migrate command.
This is the recommended method of installation if you installed nodenv with Homebrew.
$ brew install nodenv/nodenv/nodenv-npm-migrate
Or, if you would like to install the latest development release:
$ brew install --HEAD nodenv/nodenv/nodenv-npm-migrate
nodenv-npm-migrate uses npm ls --global --depth=0 to dump all installed
packages in a Node version, and then tries to npm install them into another
version.
Let's say if you have following two versions in nodenv.
$ nodenv versions
* 0.12.0 (set by /home/jawshooah/.nodenv/version)
iojs-1.6.2
$ npm ls --global --depth=0
/home/jawshooah/.nodenv/versions/0.12.0/lib
├── csslint@0.10.0
├── eslint@0.17.1
├── git-guilt@0.0.7
├── grunt@0.4.5
├── grunt-cli@0.1.13
└── npm@2.7.4
To migrate installed packages from 0.12.0 to iojs-1.6.2, use nodenv migrate.
$ nodenv migrate 0.12.0 iojs-1.6.2
$ nodenv global iojs-1.6.2
$ npm ls --global --depth=0
/home/jawshooah/.nodenv/versions/iojs-1.6.2/lib
├── csslint@0.10.0
├── eslint@0.17.1
├── git-guilt@0.0.7
├── grunt@0.4.5
├── grunt-cli@0.1.13
└── npm@2.7.4
