Errors installing pty.js (node) on OS X

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

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:

1. mkdir /tmp/pty.js
2. git clone https://github.com/chjj/pty.js.git /tmp/pty.js
3. vi /tmp/pty.js/src/unix/pty.cc
4. replace line 39: #include <util.h> with #include "/usr/include/util.h"
5. npm install -g /tmp/pty.js
6. 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!
