问题
I add some code to mixins.less:
img { &:extend(.img-responsive); }
See also: Images not responsive by default in Twitter Bootstrap 3? and https://stackoverflow.com/a/15573240/1596547
When i run grunt dist from the command line i got:
Running "recess:bootstrap" (recess) task
>> Parser error in less/mixins.less
>> 549. img {
>> 550. &:extend(.img-responsive);
>> 551. }
Warning: Use --force to continue.
Aborted due to warnings.
But when i compile it with Lessc: lessc bootstrap.less i don't find an error. (lessc 1.4.2 (LESS Compiler) [JavaScript]
)
&:extend needs Less 1.4.0. So grunt / recess use a different compiler?
update
running install grunt-contrib-less --save-dev gives:
grunt-contrib-less@0.7.0 node_modules/grunt-contrib-less
├── grunt-lib-contrib@0.6.1 (zlib-browserify@0.0.1)
└── less@1.4.2 (mime@1.2.11, mkdirp@0.3.5, ycssmin@1.0.1, request@2.27.0)
so i expect less v1.4.2 but still got this error
回答1:
It depends on the version of grunt-contrib-less you have.
Run:
npm update grunt-contrib-less
