How to generate LESS source maps without npm

Question

I am now compiling LESS with lessc(version 1.7.0) ok, but when I add --source-map, I get

SyntaxError: Cannot find module 'source-map' in /home/me/my.css

I suspect this may be because I did not install LESS with npm. How can I get the source maps?

---

Requirement (sorry): this should be the full version in VCS, and not used npmfor installation.

If you are not downloading the entire package, make sure you have the LESS libraries . When checking your repo, you can see the source maps listed there, so you may need these files.
