clean-css not found if lessc is executed from a sub directory

[srittau]

Since upgrading less from 2.7.3 to 3.0.1, --clean-css does not work anymore when less is executed from a sub directory:

srittau@moby:~$ mkdir clean-css-test && cd clean-css-test/
srittau@moby:~/clean-css-test$ npm install less less-plugin-clean-css
[...]

srittau@moby:~/clean-css-test$ ./node_modules/less/bin/lessc --clean-css foo.less 
srittau@moby:~/clean-css-test$ mkdir subdir && cd subdir
srittau@moby:~/clean-css-test/subdir$ ../node_modules/less/bin/lessc --clean-css foo.less 
Unable to load plugin clean-css please make sure that it is installed under or at the same level as less

Closing in favour of less/less.js#3181.

thanks, but 3.0.1 still can't work, do you have resolved?

@phxuecan 3.0.1 is what has this bug (please read the initial post carefully).
