Errors installing pty.js (node) on OS X - node.js

Question

I have run into an unusal problem when trying to install pty.js using node:
If I run npm install pty.js I receive this error:
> node-gyp rebuild

../src/unix/pty.cc:533:10: error: use of undeclared identifier 'forkpty'
return forkpty(amaster, name, (termios *)termp, (winsize *)winp);
^

I have node-gyp installed am running OS X with xcode + commandlines installed.
I am not sure where the problem is occurring? Could be dependencies.

Answer 1

I had the same issue with a different node package devtools-terminal.
The problem is that a header file is configured incorrectly for OSX as explained here.
This is the work around I use:
mkdir /tmp/pty.js
git clone https://github.com/chjj/pty.js.git /tmp/pty.js
vi /tmp/pty.js/src/unix/pty.cc
replace line 39: #include <util.h> with #include "/usr/include/util.h"
npm install -g /tmp/pty.js
and now npm install -g devtools-terminal should work.
This way you fix the issue in pty.js and use your local copy as the dependency for the package you with to install.
Good luck!
