The following error is seen during the installation of the Node agent:
npm ERR! @email@example.com build: `node-gyp rebuild` npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the @firstname.lastname@example.org build script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above. npm WARN Local package.json exists, but node_modules missing, did you mean to install?
From versions 2.0.0 to 2.5.1 of the Node agent, you must have installed:
- A C++ compiler toolchain (e.g., Clang, GCC or MSVC) and a POSIX-compatible
- Python (which is needed for Node-gyp, Node's build tool, to function)
Notes: If you can build other modules with C++ bindings like node-sass and sqlite3, you probably meet all of the requirements for Contrast. The official Node Docker images come with all of the prerequisites installed.
To install the necessary compiler toolchain on Windows, run
npm install -g --production
windows-build-tools. If you're using a Node version older than 8.0, you must use
windows-build-tools version 3.0 (not 4.0, the newest version).
macOS ships with the
clang compiler suite. Use
clang --version to ensure that you have the compiler installed. If Clang is not already installed, run
$ xcode-select --install to install it.
Linux distributions often ship with a C++ compiler toolchain. You can verify that the compiler is installed with
c++ --version. If you don't have a C++ compiler installed, install the
g++ package available from most Linux package managers.
