I think this is a version issue. The watershed app was written under Tethys 1...

Hi there,

 

I haven’t ran into this before, but I have a few suggestions that may work:

 

Solution 1: Try deleting the symbolic link for the app at “/home/jetli/tethys/src/tethys_apps/tethysapp/watershed_delin” and then attempt the installation again.

 

Solution 2: It seems for some reason that it is already looking for the app even though you haven’t installed it yet?  Try running tethys uninstall (insert app name) and then trying the install again maybe? (I feel like the uninstall will have an error, but it’s worth a try.) 

 

If these don’t work, what happens when you run “tethys manage start”(tms)?  Do any apps show up on the webpage?  Or does it just error out?

 

Thanks,

Dustin Brown

Agree with Dr.Ames. I think it's a version issue. The tethys_watershed_delin app (https://github.com/danames/tethys_watershed_delin.git) is developed based on Tethys 1.4. It is not updated to work with Tethys 2.
