Thanks for your report.

Until it's fixed, you can use Node 6 and it should compile fine.

[Danp2]

Tested with Node 6.1.0 and Node 6.9.2 with same results. It's something other than Node.js

[julien-f]

Probably a dependency update, you should use yarn to install them instead of npm, so you will have the same exact deps than us.

[Danp2]

Thanks for the hint on yarn. Will definitely take a look at it.

I also have this issue on debian jessie. But by using version 5.5.0 of xo-web i got a successful build.

[Danp2]

@julien-f Built fine with yarn. ;-)

[Fohdeesha]

same problem on debian, also fixed by using yarn
