[abdonrd]

With the last release (v0.11.0), polymer build doesn't work:

I have another error on Windows 7:

My current config is here. Note that I use my own boilerplate and index.html is inside src.

I am on a mac with node 4.4.5 and i get this error: It's looking for a package.json

I got the same error as abdonrd, but a slightly different stack trace (Windows 7):

Hello, init works fine with the app-drawer, but here are the errors I get with a build on Win 10 / Node 6 / Polymer cli 0.11.0

[FredKSchott]

Hey everyone, taking a look now.

[abdonrd]

Thanks @FredKSchott! 😃

[FredKSchott]

@JGSolutions I think your issue is separate from what most people are running into here. Can you create a separate issue with --verbose output included, as well as steps to reproduce from a blank directory?

If anyone else is able to reproduce the no resolver found for ... build bug on Mac, please comment here. Otherwise, I'm going to assume this is a Windows issue since I am not able to reproduce on any templates on both Node v4.4.5 & v6.1.0

[abdonrd]

@FredKSchott my terminal is in Mac: https://github.com/Polymer/polymer-cli/issues/222#issue-157318862 😅

[FredKSchott]

@abdonrd ah interesting! Can you post your node version, the full polymer build --verbose output, and steps to reproduce in an empty directory? (ex: is it as simple as polymer init application && polymer build?) This would all be super helpful for finding the bug on my machine.

[abdonrd]

@FredKSchott sure!

Node version: v6.1.0.

Give me a few minutes and I public the output.

[abdonrd]

@FredKSchott I reinstall the polymer-cli, because I had downgraded to the v0.8.0.
And... it works now. Magic! 😮

[FredKSchott]

@abdonrd great! I'd love for us to get https://github.com/yeoman/update-notifier integrated into the CLI, so that these kinds of outdated issues are easier to spot.

Going back to the assumption that this is a Windows-only issue unless anyone else can reproduce.

[abdonrd]

But I had the actual version (v0.11.0) when I had this problem... 😕
Then, I downgrade to the v0.8.0 because it works.

[FredKSchott]

@abdonrd are you saying that you can reproduce this problem on v0.8.0, but everything is working fine on v0.11.0?

[abdonrd]

@FredKSchott no, haha!

When I created the issue, I had the version v0.11.0: https://github.com/Polymer/polymer-cli/issues/222#issue-157318862

Then I downgrade to the v0.8.0 because it works.

Now I uninstall the v0.8.0 and install the v0.11.0 to follow your steps, and it works.

[FredKSchott]

huh, that's so strange... Lets chalk it up to npm weirdness and move on unless other users report it as well. Thanks for investigating!

[abdonrd]

@FredKSchott yay! I found the issue (in my project, not in the application template). Output:

[edited]

[FredKSchott]

I can reproduce on Windows in Nove v4.4.5 /w the shop template. Looking into it...

@abdonrd can you reproduce on mac with any of the default templates? I'll need steps to reproduce on my machine to help you specifically. If not, hopefully fixing this on windows fixes it for you as well.

[abdonrd]

@FredKSchott I haven't problems with application, shop and app-drawer-template.

If you want to try, I have my project here in GitHub: https://github.com/GDGSpain/gdg.es

[abdonrd]

@FredKSchott maybe is related... In my project I have a gulpfile.js.
And when I do polymer build, the gulpfile.js is executed. 😕
I has replaced the gulpfile.js code with the console.log().

[Joe-torian]

Even i am facing the same issue. i am on a windows 10 running polymer-(v-0.11.0) , node.js- (v5.11.0)

[craftyc0der]

I too am seeing this error with Windows 7. I used npm to install polymer cli this morning.

[Joe-torian]

i have reinstalled node, and polymer but the issue still remains . i guess i have to install the previous version of polymer like "abdonrd".

[Tecm0]

Having a problem. It seems like it is trying to find the bower_components inside the src folder, even though that's not where it's located.

[FredKSchott]

Okay, I think I was finally able to find and fix the issue. I'll go into more detail in the PR, but the tl;dr was that the code is currently making incorrect assumptions about Node's ability to convert between Windows, Posix, and URL paths. This was causing polymer-cli to search for bad paths, like src/bower_components/polymer/polymer.html that @Tecm0 spotted.

PR incoming, and thanks again for your patience everyone while we tracked this down.

[abdonrd]

Thanks @FredKSchott! :)

[FredKSchott]

This has been fixed in v0.11.1, which was just pushed out to npm. Please update and confirm that build now works as expected for you, and create a new issue if it does not.

[ketile]

Can confirm that polymer build with v0.11.1 works on my Windows 7 machine. Thanks a lot.

Sorry @FredKSchott... But with the new version v0.11.1 I still have the same problem. :(

[Joe-torian]

thanks @FredKSchott . its solver for me and i am on a windows-10 machine .

[uribevincent]

I updated npm and polymer-cli but the issue is still here...

[Tecm0]

That update fixed the issue for me. Thanks!

[FredKSchott]

@abdonrd looking at building on your project now
@uribevincent can you create a new issue with your environment info, polymer build --verbose output, and steps to reproduce?

[FredKSchott]

@abdonrd Your problem is that your import hrefs are absolute paths (/bower_compontents/xxx.html& /src/yyy.html). Try changing these to relative paths (../bower_components/xxx.html & yyy.html) in your src/ directory files and see if that helps.

That is the path format that polymer build expects, so that it can properly remap them for you when bundling.

[abdonrd]

@FredKSchott wow! 😮 Thanks! Now it works!
I thought I had to have absolute paths in the src directory.
Maybe it would be nice to document it.

@FredKSchott still having issues with that, this time with remote CDN libraries (socket.io and googleCharts):

I have the import on:

<script type="text/javascript" src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
<link rel="import" href="gtm-shared-styles.html">

<dom-module id="gtm-consumption-data">

[justinfagnani]

@edoardo849 this is a separate issue. Opening a new one.

[srveda]

I had the Promise rejection: Error: no resolver found

But when I changed
<link rel="import" href="/src/component1.html">
to
<link rel="import" href="../src/component1.html">
the build was complete with no errors.
