Node 12.0 support

[nschonni]

Node 12.0 was released today https://nodejs.org/en/blog/release/v12.0.0/

[shiftkey]

As a workaround, there is a documented method to use whatever versions of Node you want. This helped me upgrade a couple of projects earlier in the week:

https://github.com/atom/fs-admin/blob/master/appveyor.yml

environment:
  matrix:
  - nodejs_version: "8"
  - nodejs_version: "10"
  - nodejs_version: "11"
  - nodejs_version: "12"

platform:
  - x86
  - x64

install:
  # https://www.appveyor.com/docs/lang/nodejs-iojs/#installing-any-version-of-nodejs-or-iojs
  - ps: Update-NodeJsInstallation (Get-NodeJsLatestBuild $env:nodejs_version) $env:PLATFORM
  - npm install

Thanks @shiftkey the workaround did work. I'll leave this open till the images get updated though

@nschonni yes, please do not close :)

@lyaFinkelshteyn, is there a PS way to essentially do this in the install step?

try {
  Install-Product node $env:nodejs_version $env:platform
} catch(err) {
  Update-NodeJsInstallation (Get-NodeJsLatestBuild $env:nodejs_version) $env:platform
} 

As Node-12 is still unavailable, Update-NodeJsInstallation is the only way to get it.
But since we also test against available versions, being unable to use Install-Product for them just adds further delay.

environment:
  matrix:
    - nodejs_version: '12'
    - nodejs_version: '10'
    - nodejs_version: '8'
    - nodejs_version: '6'

@IlyaFinkelshteyn ping!

[IlyaFinkelshteyn]

Node.JS 12 is available on AppVeyor environment!

@plroebuck sorry, missed your message. This YAML would work for you (though you do not need it now, but may help later):

environment:
  matrix:
    - nodejs_version: '12'
    - nodejs_version: '10'
    - nodejs_version: '8'
    - nodejs_version: '6'

platform:
  - x86
  - x64

install:
  - ps: |
      try {
      Install-Product node $env:nodejs_version $env:platform
      } catch {
      echo "Unable to install node $env:nodejs_version, trying update..."
      Update-NodeJsInstallation (Get-NodeJsLatestBuild $env:nodejs_version) $env:platform
      }
