Permission Denied in assetic with less

Question

I'm getting odd permission issues when trying to use assetic with LESS. When I try to view the output page, I get:

/*
[exception] 500 | Internal Server Error | Assetic\Exception\FilterException
[message] An error occurred while running:
'' '/tmp/assetic_lessdbtWog'

Error Output:
sh: 1: : Permission denied


Input:
@import "../../../bundles/orkestraapplication/css/src/less/application.less";

@images-path: "../../../bundles/orkestraapplication/img";

.table-striped > tbody > tr.admin-appointment > td  {
  background-color: #FFEBBD;
}

The thing is, I'm unable to figure out what file's permissions it thinks are wrong. I've even tried a

chmod 777 * -R 

on the entire app folder, and that doesn't help.

It turns out that this issue is related to how Assetic uses node. Assetic does less compilation using node. It will concatenate the path to node with the path to a temp file that has the less to be compiled. If you don't have a node path set up, it will wind up just executing the temp file, which is unlikely to have execution permissions, thus the error.
