potential issue with 0.12.6dev5 building on windows

Hello,

I have cloned the master at 0.12.6dev5-5-g32eba5c0d.

When I try to build on windows using the instructions on the developer guide I get the following error.

C:\Users\xxx\Desktop\GitHub\bokeh\bokehjs>gulp build
C:\Users\xxx\Desktop\GitHub\bokeh\bokehjs\gulpfile.js:2
const {TSError} = require("ts-node")
      ^
SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:373:25)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)
    at Function.Module._load (module.js:300:12)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at Liftoff.handleArguments (C:\ProgramData\Anaconda3\Library\bi
s\gulp\bin\gulp.js:116:3)
    at Liftoff.<anonymous> (C:\ProgramData\Anaconda3\Library\bin\no
lp\node_modules\liftoff\index.js:198:16)
    at module.exports (C:\ProgramData\Anaconda3\Library\bin\node_mo
de_modules\flagged-respawn\index.js:17:3)

The build is successful when I change the following line in gulpfile.js
const {TSError} = require("ts-node")
to
const TSError = require("ts-node")

I understand this is a dev build and do not want to litter github with unnecessary comments. If you think it is appropriate I will raise it there.

to

const TSError = require(“ts-node”)

the build is successful, because there are no errors from typescript compiler, so this import doesn’t matter. The likely reason for this syntax not being supported is old version of node.js. bokehjs requires version >= 6.6.0 and < 7.0 (though 7.x may work, but there are known performance regressions).
