Issue running Polymer Started Kit 1.0.0

[tjsavage]

I downloaded polymer-starter-kit-dependencies-checked-in-1.0.0.zip and tried gulp serve. I got an "Unhandled rejection Error". I bypassed this by adding an error handler for the "images" gulp task and printed the error to console. The error I see is below:

Error in plugin 'gulp-cache'
Message:
spawn ENOENT
Details:
code: ENOENT
errno: ENOENT
syscall: spawn
fileName: /Users/abishek/work/dev/onroad/onroad-polymer/app/images/touch/apple-touch-icon.png

Though the server started up after handling the error, wondering what needs to be done here to fix this nicely.

Someone else ran into this yesterday and worked around it by deleting the images directory.

Could you try commenting out the caching lines in the 'images' task of your gulpfile?

//.pipe($.cache($.imagemin({ progressive: true, interlaced: true })))

and see if that solves the issue?

If not it may be worth also trying the non-checked in deps version.

I get a similar unhandled error event. If I comment out the image caching in gulpfile.js, it completes the build but then throws:

events.js:72
throw er; // Unhandled 'error' event
^
Error: spawn EACCES
at errnoException (child_process.js:1011:11)

[addyosmani]

@nafem are you using the version with checked in deps or without?

[nafem]

With checked in deps. Running Ubuntu 14.04
I have also tried without deps but get the following error when running npm install

npm WARN package.json [email protected] No repository field....

But this is probably a different issue

[addyosmani]

@nafem it looks like you have an older version of Node and npm. Could you upgrade to the latest Node and try again? https://nodejs.org/

[fones]

After upgrading node to last version problem still occurs (macosx)
When comment out this line
.pipe($.cache($.imagemin({ progressive: true, interlaced: true })))
it works!

[koenhendriks]

I'm running Linux Mint 17 with latest NodeJs (v0.12.4) and npm (2.10.1)

I tried this with the checked in dependencies version 1.0.1 and i still have this issue.

Here is the log:

if i comment out .pipe($.cache($.imagemin({ progressive: true, interlaced: true }))) i get a new error:

[addyosmani]

@koenhendriks does this issue happen with the non-checked in deps version too?

[koenhendriks]

@addyosmani just tested, I don't get any errors with the non-checked in deps.

[addyosmani]

Thanks for confirming. I think we may be out of luck with the checked-in dependencies version. When we would generate the zip for it on a *nix machine, Windows users would run into issues with similar errors and when generating on Windows, the opposite appears to happen.

To minimize confusion, I'm considering deprecating the checked-in deps version as an option for now.

@fones you mentioned you were on Mac. Did you have any issues with the non-checked in deps version?

[fones]

@addyosmani I've tried only without deps. I've checked out master branch at commit 6078e4e7b6 and only issue with .pipe($.cache($.imagemin({ progressive: true, interlaced: true }))) occurs.

[addyosmani]

Hey folks. If you're still running into this issue, I just wanted to mention we've updated our README to be a little more specific with Node versions. We currently recommend Node 0.12.x and above. To check/update accordingly, please see https://github.com/PolymerElements/polymer-starter-kit#prerequisites-for-everyone

[arthurvr]

Is anyone still having this issue on latest Node using the latest PSK?

[cyberabis]

With the latest kit, this is solved for me.

[addyosmani]

Thanks @cyberabis. Would be great to get a few more confirmations and we can then close this.

[koenhendriks]

Worked for me to!
