Failed to parse schemas: no valid YANG model found! #9

Closed Matt-Texier closed 5 years ago

Matt-Texier commented 5 years ago

Hi,

I am running ANX against Cisco IOS-XR router.

When I launch exploration, the whole router's models seems to uploaded by anx server but once done and all model uploaded it finally fails showing a red restangle that mention: 

Failed to parse schemas: no valid YANG model found!

Here is the trailing logs of the application:

Am I missing something ? Should I install manually some yang models somewhere ?

Thanks for your help, Matthieu.

Try creating an empty directory "yangcache" in the "anx" base directory or one directory above your working directory when launching anx. I think it tries to write / read to that directory but it doesnt exist. Alternatively you can try disabling caching in the login screen.

Success, I had to create a yangcache directory under my home directory.

Thanks for your help, Matt.
