Add node-v48-win32-ia32?

[DonKarlssonSan]

Hi,

I'm trying to use canvas-prebuilt on Azure Functions but there is an error during installation:

node-pre-gyp ERR! install error

It's looking for canvas-prebuilt-v1.6.5-prerelease.1-node-v48-win32-ia32.tar.gz but that does not exist so it fails. I saw this comment in the readme:

I have some ideas on how to get these working with cross-compilation if people request it. I plan to add Linux/ARM

So I'm wondering if it is possible to add Windows x86/ia32 builds as well? (node-v48-win32-ia32)

The node version in Azure Functions is currently locked at 6.5.0.

I've tried switching my Azure Function to 64 bit but that made no difference. Somehow the npm scripts detects the platform arch as 32.

(Sorta off-topic: Is it easy for you to see the output of process.arch and require("os").arch() with a 64-bit function? Curious if that's a bug in Azure's deployment or in node-pre-gyp's detection.)

[DonKarlssonSan]

Aha! Conflicting info. Azure Functions seems to be the one to blame for reporting x86 to node-pre-gyp

D:\home>node test.js
ia32 ia32

D:\home>node --version
v6.5.0

D:\home>cat test.js
console.log(process.arch, require("os").arch());

System info

System up time: 1.21:10:02 OS version: Microsoft Windows NT 6.2.9200.0 64 bit system: True 64 bit process: True

Environment variables

REMOTEDEBUGGINGBITVERSION = vx64 REMOTEDEBUGGINGPORT = REMOTEDEBUGGINGVERSION = 11.0.611103.400 SCM_SKIP_SSL_VALIDATION = 0 SCM_USE_FUNCPACK = 0 ScmType = GitHub SITE_BITNESS = AMD64

If it's an option for you, you can pass --target_arch=x64 to npm install and that should override node-pre-gyp's choice. I probably won't get around to adding 32 bit support seeing as I still haven't done ARM and that has been a popular request 😕

[DonKarlssonSan]

Thanks! I will try that.

1. Switching Azure Function to x64 can't help because:

   $ node -p "process.arch"
   > ia32

2. --target_arch=x64 can't help too, because Node.js process arch is ia32 (i.e. they install x32 Node.js version on a x64 machine)
3. Some people says, that we can try Azure Functions on Linux to achieve this, but in my case it didn't help, because it has Node.js 6.11 :grin:

So, as for now, no way to install and use node-canvas on Azure Function App
