Loading error when installing with `make sdist` about declarativewidgets HOT 8 CLOSED

Made some updates to README. Please make sure that you are installing and running on a Python3 environment.

I just went through the same exercise of having a Python 2.7 env where I was running Jupyter and pip installing packages and it was failing... The actual failure could be seen in loading the extension on IPython 3.2.1 running using python 2.7.

[W 15:35:57.201 NotebookApp] Error loading server extension urth.widgets.urth_import
    Traceback (most recent call last):
      File "/usr/local/lib/python2.7/dist-packages/IPython/html/notebookapp.py", line 998, in init_server_extensions

One more thing... make sure that you are using Chrome. Until issue #21 is fixed, its the only browser that will work. I mention since your error is loading web components-lite.min.js and that tells me that you are not using Chrome.

So I switched to Chrome and IPython 3.2 (running on python 3.5) and got a little further :) Now, I get the following errors:

GET http://localhost:8888/urth_components/urth-core-bind/urth-core-bind.html 404 (Not Found)

I can see all those files in ~/.ipython/nbextensions/urth_widgets/urth_components/. I have tried to symlink .ipython/nbextensions/urth_widgets/urth_components/ to .ipython/nbextensions/urth_components/ but that did not help.

Did you hit that problem too?

Ah! Don't do any symlink. The extension adds a route for '/urth_components' and it serves elements.

The extended link element on the notebook will trigger installation using bower.

You are probably missing 'bower'. Try that and I'll revise the README.

I have installed bower. Bower does appear to be initialized properly, but the urth_components still fail to load unfortunately...

Bower root is:  /urth_components
main.js?v=20151016101012:10 Custom JS loaded
init.js?v=20151016101012:52 GET http://localhost:8888/urth_components/urth-core-bind/urth-core-bind.html 404 (Not Found)

init.js?v=20151016101012:52 GET http://localhost:8888/urth_components/urth-core-import/urth-core-import.html 404 (Not Found)

One more thing: So far, I have been installing the widget extension using pip: pip install urth-widgets-nbexts-0.1.dev0.tar.gz. However, today I tried python3 setup.py install and I got an install time error. I am not sure whether the two problems are related.

...
running install_scripts
Installing notebook extension
removing /Users/tbh/.ipython/nbextensions/urth_widgets
copying urth_widgets -> /Users/tbh/.ipython/nbextensions/urth_widgets
error: [Errno 2] No such file or directory: 'urth_widgets'

Thanks for helping me. I feel like we are close :)

Try installing with pip3 both Jupyter and the extension. Please attach your server logs. Hoping the is something there that can help.

@thibaudh Any update here?

from declarativewidgets.

Victory! After reinstalling ipython using pip3 install "ipython[notebook]==3.2.2", then installing the dashboard and the declarative widgets withpip3 install dist/...`, it finally works. Thanks for your help!

So there seems to be a subtle difference between installing extensions with pip and using ./setup.py install. The setup.py way has never worked for me.

One more question: how high on your priority lists are:

• Crossbrowser support (Firefox and Safary)?
• Python 2.7 support?

These might be blockers for us.

Thanks,
Thibaud

Great!!!

Safari and Firefox should be working on master.

About Python 2.7... We moved to Python 3 because, AFAIK, it is the Python platform of Jupyter going forward. If you want to open an issue on Python 2.7, go ahead and we'll move the conversation there.
