Make compatible with io.js

../node_modules/nan/nan.h:409:19: error: no type named 'ExternalAsciiStringResource' in 'v8::String'; did you mean 'ExternalStringResource'?

io.js ships a newer V8 version where String::ExternalAsciiStringResource
has been replaced with String::ExternalOneByteStringResource

via nodejs/nan#223 via nodejs/node#386

Whoops, I misread the logs. This is actually failing on nan.h. I'll keep this open incase the dependency needs a bump, but the semver here seem loose enough that it shouldn't be an issue.

[snostorm]

Okay, so nan v1.5 is out (and v1.4 is going to get a patch for io.js support as well) but them semver on pty.js is locking the project to v1.0.0 <= v0.1.1.

Updating this request to: can we get a semver bump on this dependency please?

nodejs/node#456

@snostorm would a semver bump be the only thing required to fix this issue?

[snostorm]

I think that was all that was needed. I'll need to re-test to be sure. If it was that simple ... not sure why I didn't just PR, sorry.

[snostorm]

I think this will depend on nodejs/nan#265 to land -- the latest nan+iojs I have seems to hit the issue, which builds when built against the fix living via https://github.com/touhou-gensokyo/nan.git#master --

But the npm test still fails after a "successful" compile

New pty.js released using nan v1.6.2. Hopefully this fixes something.

I'm still getting the error..

@chjj it builds with node-0.12 and iojs but the tests are all failing: timing out.

[dannydulai]

the example from the readme doesnt work with node-0.12.0

it doesnt launch the right program, and prints out that it is running node.

[javruben]

@chjj We'd love to have node-0.12 support. Is there anything we can do to help?

[hmalphettes]

There is also @Gottox rewrite of pty.js: https://github.com/Gottox/child_pty
I am no expert here; I only checked out child_pty and ran the tests under node-0.10 iojs and node-0.12.
Maybe @chjj and @Gottox could give us a hint as to what direction we should take?
