@nodenv/node-build - npm

node-build is a command-line tool that simplifies installation of any Node version from source or precompiled binary on Unix-like systems.

It is available as a plugin for nodenv as the nodenv install command, or as a standalone program as the node-build command.

Upgrade with:

Clone as nodenv plugin using git

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

Upgrade with:

git -C "$(nodenv root)"/plugins/node-build pull

Install manually as a standalone program

First, download a tarball from https://github.com/nodenv/node-build/releases/latest. Then:

tar -xzf node-build-*.tar.gz
PREFIX=/usr/local ./node-build-*/install.sh

# As a nodenv plugin
$ nodenv install --list                    # lists all available versions of Node
$ nodenv install 10.13.0                   # installs Node 10.13.0 to ~/.nodenv/versions

# As a standalone program
$ node-build --definitions                 # lists all available versions of Node
$ node-build 10.13.0 ~/local/node-10.13.0  # installs Node 10.13.0 to ~/local/node-10.13.0

Warning node-build mostly does not verify that system dependencies are present before downloading and attempting to compile Node from source. Please ensure that all requisite libraries such as build tools and development headers are already present on your system.

Firstly, if a precompiled binary exists for your platform, node-build downloads and installs it. Otherwise it will build node from source. Basically, what node-build does when installing a Node version is this:

Downloads an official tarball of Node source code;
Extracts the archive into a temporary directory on your system;
Executes ./configure --prefix=/path/to/destination in the source code;
Runs make install to compile Node;
Verifies that the installed Node is functional.

By default, node-build will attempt to match one of the precompiled binaries to your platform. If there is a binary for your platform, it will install it instead of compiling from source. To force compilation, pass the -c or --compile flag.

To install a version of Node that is not recognized by node-build, you can specify the path to a custom build definition file in place of a Node version number.

Check out default build definitions as examples on how to write definition files.

Generating Latest-Release Build Definitions

Additionally, check out the node-build-update-defs plugin. It generates the standard build definitions for releases available from nodejs.org. This allows you to install node versions as soon as they are available from nodejs.org, without waiting for node-build itself to provide them. Once installed:

nodenv update-version-defs

Custom Build Configuration

The build process may be configured through the following environment variables:

Variable Function TMPDIR Where temporary files are stored. NODE_BUILD_BUILD_PATH Where sources are downloaded and built. (Default: a timestamped subdirectory of TMPDIR) NODE_BUILD_CACHE_PATH Where to cache downloaded package files. (Default: ~/.nodenv/cache if invoked as nodenv plugin) NODE_BUILD_HTTP_CLIENT One of aria2c, curl, or wget to use for downloading. (Default: first one found in PATH) NODE_BUILD_ARIA2_OPTS Additional options to pass to aria2c for downloading. NODE_BUILD_CURL_OPTS Additional options to pass to curl for downloading. NODE_BUILD_WGET_OPTS Additional options to pass to wget for downloading. NODE_BUILD_MIRROR_CMD A command to construct the package mirror URL. NODE_BUILD_MIRROR_URL Custom mirror URL root. NODE_BUILD_MIRROR_PACKAGE_URL Custom complete mirror URL (e.g. http://mirror.example.com/package-1.0.0.tar.gz). NODE_BUILD_SKIP_MIRROR Bypass the download mirror and fetch all package files from their original URLs. NODE_BUILD_ROOT Custom build definition directory. (Default: share/node-build) NODE_BUILD_TARBALL_OVERRIDE Override the URL to fetch the node tarball from, optionally followed by #checksum. NODE_BUILD_DEFINITIONS Additional paths to search for build definitions. (Colon-separated list) CC Path to the C compiler. NODE_CFLAGS Additional CFLAGS options (e.g., to override -O3). CONFIGURE_OPTS Additional ./configure options. MAKE Custom make command (e.g., gmake). MAKE_OPTS / MAKEOPTS Additional make options. MAKE_INSTALL_OPTS Additional make install options. NODE_CONFIGURE_OPTS Additional ./configure options (applies only to Node source). NODE_MAKE_OPTS Additional make options (applies only to Node source). NODE_MAKE_INSTALL_OPTS Additional make install options (applies only to Node source).

Both nodenv install and node-build commands support the -p/--patch flag to apply a patch to the Node source code before building. Patches are read from standard input:

# applying a single patch
$ nodenv install --patch 11.1.0 < /path/to/node.patch

# applying a patch from HTTP
$ nodenv install --patch 11.1.0 < <(curl -sSL http://git.io/node.patch)

# applying multiple patches
$ cat fix1.patch fix2.patch | nodenv install --patch 11.1.0

All Node definition files bundled with node-build include checksums for packages, meaning that all externally downloaded packages are automatically checked for integrity after fetching.

See the next section for more information on how to author checksums.

To speed up downloads, node-build can fetch package files from a mirror. To benefit from this, the packages must specify their checksum:

 # example:
 install_package "node-v12.0.0" "https://nodejs.org/dist/v12.0.0/node-v12.0.0.tar.gz#<SHA2>"

node-build will first try to fetch this package from $NODE_BUILD_MIRROR_URL/<SHA2> (note: this is the complete URL), where <SHA2> is the checksum for the file. It will fall back to downloading the package from the original location if:

the package was not found on the mirror;
the mirror is down;
the download is corrupt, i.e. the file's checksum doesn't match;
no tool is available to calculate the checksum; or
NODE_BUILD_SKIP_MIRROR is enabled.

You may specify a custom mirror by setting NODE_BUILD_MIRROR_URL.

If a mirror site doesn't conform to the above URL format, you can specify the complete URL by setting NODE_BUILD_MIRROR_PACKAGE_URL. It behaves the same as NODE_BUILD_MIRROR_URL except being a complete URL.

For more control over the construction of the mirror url, you can specify a command by setting NODE_BUILD_MIRROR_CMD. node-build will invoke NODE_BUILD_MIRROR_CMD with two arguments: package_url and checksum. The provided command should print the desired mirror's complete package URL to STDOUT.

Keeping the build directory after installation

Both node-build and nodenv install accept the -k or --keep flag, which tells node-build to keep the downloaded source after installation. This can be useful if you need to use gdb and memprof with Node.

Source code will be kept in a parallel directory tree $(nodenv root)/sources when using --keep with the nodenv install command. You should specify the location of the source code with the NODE_BUILD_BUILD_PATH environment variable when using --keep with node-build.

Retry installation without v/node-/node-v prefix

The nodenv-install plugin can attempt a retry if the installation failed due to a missing definition file. If the given node version name begins with 'v', 'node', or 'node-v', the retry will drop the prefix and try again. For instance, if nodenv install node-v11.0.0 fails because a definition file does not exist by the name "node-v11.0.0", it will retry as "11.0.0". For this retry to be attempted, the environment variable NODENV_PREFIX_RETRY must be non-empty.

Please see the node-build wiki for solutions to common problems. Also, check out the ruby-build wiki.

If you can't find an answer on the wiki, open an issue on the issue tracker. Be sure to include the full build log for build failures.
