Can't authenticate?

[jona-sassenhagen]

I've installed via pip. Opening a new notebook, I get the cite toolbar items. When I click it, a new tab opens at http://localhost:8888/cite2c/zotero_oauth and I get a popup Opened a new tab to authenticate with Zotero. Once you have done this, please click OK.. However, the new tab (cite2c/zotero_oauth) is a 404, and I can't see how I can authenticate anything. What am I doing wrong? Thanks!

Have you started a new notebook server since you installed it? It adds a handler for /cite2c/zotero_oauth, but unfortunately the notebook server won't use the new handler until you restart it.

Thanks, that did it. I could make a PR to the README.md making this explicit?

[takluyver]

That would be good, thanks!

I am having the same issue, I installed the extension, restart the notebook but I am still getting this.

I am using a mac and the latest version of jupyter

if this can help here is the log I am getting after restarting my jupyter posterior to the extension installation

The No module named 'cite2c' error looks like it's not installed correctly - Jupyter can't find the Python module.

It's been some years since I touched cite2c, though, so it's quite possible that even without that, changes in Zotero or in Jupyter may mean it no longer works.
