node-sass: Post-install build.js fails

I’m attempting to install node-sass as a dependency of an advanced ng2/electron seed inside a Docker container running behind a corporate firewall controlled by a Jenkins CI instance.

• NPM version (npm -v): 3.10.8

• Node version (node -v): v6.9.1

• Node Process (node -p process.versions): { http_parser: ‘2.7.0’, node: ‘6.9.1’, v8: ‘5.1.281.84’, uv: ‘1.9.1’, zlib: ‘1.2.8’, ares: ‘1.10.1-DEV’, icu: ‘57.1’, modules: ‘48’, openssl: ‘1.0.2j’ }

• Node Platform (node -p process.platform): linux

• Node architecture (node -p process.arch): x64

• node-sass version (node -p "require('node-sass').info"):

• npm node-sass versions (npm ls node-sass): not applicable, attempting to install v4.1.1

This is the relevant part of the respective Dockerfile, it is build from node:6.9.1 which is itself based on Debian Jessie.

ENV SKIP_SASS_BINARY_DOWNLOAD_FOR_CI=1 ENV SASS_BINARY_PATH=/usr/base/binaries/ ENV SASS_BINARY_NAME=linux-x64-48 COPY ./ /usr/base

The correct copy process of the binary has been confirmed.

The installation process fails during the postinstall call to build.js:

node-sass@4.1.1 postinstall /usr/base/node_modules/node-sass node scripts/build.js

Binary found at /usr/base/binaries/

Testing binary

Binary has a problem: { Error: Cannot find module ‘/usr/base/binaries/’ at Function.Module._resolveFilename (module.js:469:15) at Function.Module._load (module.js:417:25) at Module.require (module.js:497:17) at require (internal/module.js:20:19) at module.exports (/usr/base/node_modules/node-sass/lib/binding.js:19:10) at Object.<anonymous> (/usr/base/node_modules/node-sass/lib/index.js:14:35) at Module._compile (module.js:570:32) at Object.Module._extensions…js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) code: ‘MODULE_NOT_FOUND’ }

Building the binary locally

Building: /usr/local/bin/node /usr/base/node_modules/node-gyp/bin/node-gyp.js rebuild --verbose --libsass_ext= --libsass_cflags= --libsass_ldflags= --libsass_library=

The following local compilation via node-gyp fails, again because the following GET is blocked by a firewall:

GET https://nodejs.org/download/release/v6.9.1/node-v6.9.1-headers.tar.gz

While this isn’t really the problem, I’m also open to workarounds based on supplying cached node header files to node-gyp.

Any ideas?
