Status: RESOLVED WORKSFORME

(Testing :: web-platform-tests, defect)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

I got the following error when I do ./mach wpt-update to add new expected failures.

$ ./mach wpt-update ../new_results.json
ERROR: Cannot install html5lib==1.0.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested html5lib==1.0.1
    The user requested (constraint) html5lib==1.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

I think this should have been fixed by Bug 1723237
