I tried to build kibana using the instructions from [https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md](https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md). At the last step: grunt dev, I get the following error: Running "dev" task Running "less:src" (less) task FileError: 'lesshat.less' wasn't found in /opt/JS/kibana/kibana/src/kibana/components/agg\_table/agg\_table.less on line 1, column 1: 1 @import (reference) "lesshat.less"; 2 @import (reference) "../../styles/theme/\_variables.less"; Warning: Error compiling /opt/JS/kibana/kibana/src/kibana/components/agg\_table/agg\_table.less Use --force to continue. Aborted due to warnings. Any idea what went wrong? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
