Troubleshooting¶
Disallowed MIME type error on Windows¶
Apparently Windows system-wide MIME type configuration sometimes won’t load up JavaScript modules in certain browsers. The errors would be something like Loading module from “http://127.0.0.1:8000/static/js/unicorn.js” was blocked because of a disallowed MIME type (“text/plain”)
or Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain".
One suggested solution is to add the following to the bottom of the settings file:
# settings.py
if DEBUG:
import mimetypes
mimetypes.add_type("application/javascript", ".js", True)
See this Windows MIME type detection pitfalls article, this StackOverflow answer, or issue #201 for more details.
