系统:ubuntu17

装了python2.7.13, 之后陆续装了python3.5.3, python3.6.1

本来默认的python版本是2.7, 改为3.6后, 就出现gnome-terminal用不了的问题:

$ gnome-terminal
Traceback (most recent call last):

$ sudo cp _gi_cairo.cpython-35m-x86_64-linux-gnu.so _gi_cairo.cpython-36m-x86_64-linux-gnu.so

OK, 问题解决

d04381ec "HighContrast" is not a possible requested theme. So `_UpdateBackgroundForMica()` would force the settings UI to be light or dark. To fix this, we just check if we're in high contrast mode and, if so, we don't bother setting the requested theme. 8 天前
e83434ff Turns out that having the styles for the KeyChordText and ParsedCommandLineText be empty for high contrast mode caused the issue. Since we're already using theme resources for the colors, we automatically adjust properly to whatever the high contrast theme is (Thanks XAML!). Bonus points: - we didn't need the theme dictionaries anymore, so I just moved them to the ResourceDictionary directly - ParsedCommandLineTextBlockStyle isn't used. So I removed it altogether. Validated command palette with multiple high contrast themes. See PR thread for demo. Closes #17914 8 天前
