    Build Status

    node-build-prerelease is an nodenv plugin (or more precisely, a node-build plugin) that provides build definitions for nodejs prereleases (primarily release candidates).


    Installing with Homebrew (for OS X users)

    Mac OS X users can install node-build-prerelease with the Homebrew. Installing via Homebrew will make node-build aware of nodejs prereleases automatically.

    This is the recommended method of installation if you installed nodenv or node-build with Homebrew.

    brew install nodenv/nodenv/node-build-prerelease

    There is the added delay between when a new version of node-build-prerelease is released, and when the homebrew formula is updated to point to it. Typically this additional delay is only a matter of days and is well worth the simplicity of using homebrew to manage nodenv plugins.

    (And if you really want to be on the bleeding edge of node-build, you can skip waiting on node-build/node-build-prerelease to update and scrape new node releases yourself with node-build-update-defs.)

    Installing via git-clone

    Installing node-build-prerelease as a nodenv plugin will make node-build aware of the prerelease build definitions automatically.

    git clone https://github.com/nodenv/node-build-prerelease.git $(nodenv root)/plugins/node-build-prerelease

    This will install the latest development version of node-build-prerelease into the $(nodenv root)/plugins/node-build-prerelease directory. From that directory, you can also check out a specific release tag. To update node-build-prerelease, run git pull to download the latest changes or use nodenv-update.

    Installing via npm

    Installing via npm is possible, though not really recommended. Keep in mind that there is the risk you are installing a nodenv plugin into a node that is itself managed by nodenv.

    npm install -g @nodenv/node-build-prerelease

    After installing, node-build will need to be made aware of the new build definitions. see setting node_build_definitions

    Installing manually

    For precise control over the installation, you can install it manually.

    git clone https://github.com/nodenv/node-build-prerelease.git
    cd node-build-prerelease

    This will install node-build-prerelease into /usr/local. If you do not have write permission to /usr/local, you will need to run sudo ./install.sh instead. You can install to a different prefix by setting the PREFIX environment variable. (Be aware, if you install to a prefix other than that which node-build is installed, you will need to manually set NODE_BUILD_DEFINITIONS.)

    To update node-build-prerelease after it has been installed, run git pull in your cloned copy of the repository, then re-run the install script. After installing, node-build will need to be made aware of the new build definitions. see setting node_build_definitions


    If installed via Homebrew, as a nodenv plugin, or manually using the same PREFIX as node-build, then node-build should automatically be aware of the new prerelease build definitions. Verify by running nodenv install --list to see if it includes the release candidate builds. (e.g. 8.0.0-rc.2)

    Otherwise, node-build will need to be made aware of the new build definitions manually.


    NODE_BUILD_DEFINITIONS is a colon-separated list of paths that include build definitions.

    This is done by adding /path/to/node-build-prerelease/share/node-build to the NODE_BUILD_DEFINITIONS variable. You can add node-build-prerelease's share path to it in your .bashrc:

    export NODE_BUILD_DEFINITIONS=$NODE_BUILD_DEFINITIONS:/path/to/node-build-prerelease/share/node-build

    Or add it only when necessary:

    NODE_BUILD_DEFINITIONS=$NODE_BUILD_DEFINITIONS:/path/to/node-build-prerelease/share/node-build nodenv install --list

    Either way, you'll need to know the exact location of where node-build-prerelease was installed. If installed globally via a nodenv-managed npm, it would look something like: $(nodenv prefix)/lib/node_modules/@nodenv/node-build-prerelease/share/node-build. If installed manually to PREFIX=/some/path, it would look something like: /some/path/share/node-build.

    Passing build definition directly

    Both nodenv install and node-build accept a path to a custom definition file in place of a version name.

    nodenv install /path/to/node-build-prerelease/share/node-build/8.0.0-rc.2


    node-build /path/to/node-build-prerelease/share/node-build/8.0.0-rc.2 /dest/path/8.0.0-rc.2




    npm i @nodenv/node-build-prerelease
