I am sorry to hear that it didn't work for you. I'm not sure exactly what happened from the log. Did you download or clone the GitHub repository? Try running npm install from the extensions-api folder where you either cloned or downloaded and extracted the zip file. This folder will have the package.json file. After you run the install script, run npm start.

See this issue. It might be an npm windows installer bug if you updated from 4 to 6 using an msi: https://github.com/npm/npm/issues/11383

@radhakrishna10281 did @geordielad's suggestion help resolve the issue? Will close this if it's been resolved.

I followed the instructions, and just see the Learn more link under Extensions in the Dashboard Pane of Tableau near (0000.17.1128.0318) 64-bit

The npm server is runing because when I navigate to http://127.0.0.1:8765/ I see the index.html file content.

Do you need to copy anything other than the .trex files into the ~\Tableau Repository\Extensions directory?

I noticed the .trex files on the master had extension-version="0.6.0" - but after I changed that to extension-version="0.7.0" it didn't fix anything. I read the Create a Tableau Extension and Tableau Extension Manifest documentation, and this didn't give any clues.

It's not what @geordielad suggests from my read, that issue was related to upgrading from node v4. to v6. using MSI installer, both @radhakrishna10281 and I have node v6. I have 6.10.3.

@datocrats-org - sounds like your npm server was running correctly. You are looking at the index.html landing page. The Extension samples are running in the folders under Samples and Tutorial and should appear when you drag them on to the dashboard, provided the .trex files are in the Tableau Repository( Beta)\Extensions folder.
I don't want to make you run around... but you might want to switch to the latest Tableau Developer Preview release (https://prerelease.tableau.com) and download or clone the latest version of master. In the latest 0.8 release, you no longer have to place the .trex files in the Tableau Repository( Beta)\Extensions directory. You can browse for them.
Also, you might try looking at the log files to see if the .trex files are getting parsed correctly. See Using Log files..

Closing this as it's been over a year and we've officially released extensions since then. If you are still seeing this issue with our current release please re-open!
