Error when running app #1

Closed azilnik closed 9 years ago

azilnik commented 9 years ago

I have Node installed. I am trying to run this app on a URL, to see if it works. I keep getting an error with the trim() function.

.../turnstile.js:19 exits: line.shift().trim() ^ TypeError: Cannot call method 'trim' of undefined at parseLine (/Users/ari.zilnik/Hadoop/hdfs-testing/node_modules/mta-turnstiles/lib/streams/turnstile.js:19:27) at /Users/ari.zilnik/Hadoop/hdfs-testing/node_modules/mta-turnstiles/lib/streams/turnstile.js:49:5 at Array.forEach (native) at TurnstileStream._transform (/Users/ari.zilnik/Hadoop/hdfs-testing/node_modules/mta-turnstiles/lib/streams/turnstile.js:48:14) at TurnstileStream.Transform._read (_stream_transform.js:179:10) at TurnstileStream.Transform._write (_stream_transform.js:167:12) at doWrite (_stream_writable.js:225:10) at writeOrBuffer (_stream_writable.js:215:5) at TurnstileStream.Writable.write (_stream_writable.js:182:11) at Request.ondata (stream.js:51:26)

Hi! I just merged a PR which may fix this issue. Can you give it another shot?

Same here.

      exits: line.shift().trim()

I just updated the package on npm. Looks like it is fixed now.

If not, can you give me the command you are running this with?

Works like a charm. Thanks!
