Thank you, I"ve added to `MANIFEST.in`.

Ah I didn't read the logs enough, the [failure on master](https://github.com/encode/django-rest-framework/runs/7723994188?check_suite_focus=true) was due to the missing source map: ``` dist run-test: commands[0] | ./runtests.py --no-pkgroot --staticfiles Post-processing 'rest_framework/css/bootstrap-theme.min.css' failed! ......

You can also add source map files, even empty ones, to your project's static folder. Use the right file names: `rest_framework/static/rest_framework/css/bootstrap-theme.min.css.map` and `rest_framework/static/rest_framework/css/bootstrap.min.css.map`
