Node-sass: Post-install build.js fails

[TekSiDoT]

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:

[email protected] 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.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?

By setting ENV SKIP_SASS_BINARY_DOWNLOAD_FOR_CI=1 you're forcing a local compilation. In order for node-gyp to compile locally it needs the headers for your version of node. By blocking that download the binary cannot be compiled so the build step will fail.

[TekSiDoT]

Is using SKIP_SASS_BINARY_DOWNLOAD_FOR_CI and supplying a pre-downloaded version via SASS_BINARY_PATHinstead not an intended workflow?

[xzyfer]

No it is not. SKIP_SASS_BINARY_DOWNLOAD_FOR_CI is an an internal, undocumented flag scheduled for removal. SASS_BINARY_PATH is all you need.

[TekSiDoT]

great, thank you for the clarification, I'll be able to confirm on Tuesday.

[TekSiDoT]

Unfortunately, the problem remains unchanged even after removing the SKIP_SASS_BINARY_DOWNLOAD_FOR_CI ENV flag

[xzyfer]

I expect the current problem to be different. We cannot help without a full install log.

[TekSiDoT]

I have created a gist containing the complete install log along with the used Dockerfiles, thanks for your efforts.

[xzyfer]

Sorry for the delay, I've started looking into this, it does appear to be bug.

[TekSiDoT]

No worries, I appreciate you investing time in this, looking forward to your results.

Any updates?

Electron isn't a supported environment for node-sass

[TekSiDoT]

@nschonni This is not about running node-sass in Electron but about a bug handling a flag concerning the offline use of node-sass during a build process. This same could be reported using any number of projects (among others: @angular/cli).

[xzyfer]

Sorry this is a legitimate issue I just haven't had the time to get around to yet.

[TekSiDoT]

Thanks for your time!

[nschonni]

The headers is the target option from node-gyp https://github.com/nodejs/node-gyp#command-options
When supplying the sass-binary-path, it assumes that is the full path including the binding.node https://github.com/sass/node-sass/blob/a14fbe5b3bf374c6d4192b7e2079e3812712fa92/test/runtime.js#L86
