I am new to Lighttable, how could I fix it ?

Answer 1

Reinstall the plugin and check where it is being installed would be the quickest route. The other alternative is to embed the plugin into the project which would take you a bit of extra time.

Here would be the two quickest suggestions:

1. Pull the plugin out. Then do git clean -fdx and be sure the plugin is gone. Then reinstall from scratch.

2. Find where the plugin is located. By default, clojure and groovy typically are located at LightTable/deploy/plugins. If it is, then this is easy, do a git pull on the directory because the .jar may not be in the same location as the plugin itself.

Try number 1 first. It is simpler and faster to accomplish.
