Your GitHub issue on this topic:
Is a duplicate of these:
This seems to be a hot topic.
I forked the repository and started to code a patch for you, which seems to center around this segment:
https://github.com/SublimeLinter/SublimeLinter/blob/4ef4b2ca08e0224b8af59bf3406c4927432efb94/sublimelinter/modules/base_linter.py#L380
But then, it dawned on me... environment variables. Since this seems to be a prevalent issue with many unsolved requests, it seems that you ought to set the PATH
environment variable, and place the location you are looking to be found first, earlier in that variable.
Don't know your Windows version, and the process to set an environment variable will be different for your version, so you ought to experiment with that, and then use that method as the standard for all your environments ( as it seems implied you have more than one to maintain ).
Update: Ruby seems to allow relative paths, but JavaScript does not, because of this section:
https://github.com/SublimeLinter/SublimeLinter/blob/4ef4b2ca08e0224b8af59bf3406c4927432efb94/sublimelinter/modules/base_linter.py#L380
Which hinges on: JAVASCRIPT_ENGINE_WRAPPERS_PATH
So the answer is, unless that code is adapted, no. Relative paths cannot be used for JS.
