following is a clip in the file of "shaka-player.compiled.debug.map",

you see that the paths are all the absolute paths.
is there any way to change to use the relative path?

the reason i want to use the relative path is that when i debugged in chrome using source map
i got the following error

Source map http://localhost:8000/shaka-player.compiled.debug.map points to the files missing from the workspace: [http://localhost:8000/d:/venus/shaka-player/third_party/closure/goog/base.js, http://localhost:8000/d:/venus/shaka-player/lib/polyfill/patchedmediakeys_v01b.js, http://localhost:8000/d:/venus/shaka-player/lib/abr/ewma.js, …]

if map file uses the relative path, the issue will gone.

What version are you using and on what platform? Have you tried with a clean version on master? This is a duplicate of #323 and should have been fixed in 58ac690.

my platform is :
OS: windows 10
