[Fixed] Errors with STDIN

[arnaudlimbourg]

Hello,

I tried to report that problem earlier but as the code example was not correct due to copy paste errors I have redone the whole process to reproduce the error.

$ mkvirtualenv uglifybug
$ npm install uglify-js
$ npm list
  /Users/arnaud/.virtualenvs/uglifybug/lib

Running the following command does output any error

$ /usr/bin/env uglifyjs jquery-1.8.3.js

This will hopefully help and make the issue clearer.

I may be doing something wrong but I get this result consistently.

This has been reported before. I can't reproduce it on Linux though; the previous report also looked like it was on a Mac — perhaps there's a bug in /usr/bin/env on OSX, it seems to mess with stdin somehow. UglifyJS reads the standard input from /dev/stdin.

Sorry but I don't have a Mac, therefore I've no idea how to investigate.

[arnaudlimbourg]

@mishoo it is indeed on a mac, I somehow forgot to specify that. I will try to have a deeper look.

I just ran into this problem too. I'm also on a Mac.

I also struggle with this problem on OSX, do you when a new version containing commit f83aca6 will be released to npm?
Thanks!

This error does not appear anymore.
