为组件动态添加样式报错{ expected css(css-lcurlyexpected)？

{

"owner": "\_generated\_diagnostic\_collection\_name\_\#1",

"code": "css-lcurlyexpected",

"severity": 8,

"message": "{ expected",

"source": "css",

"startLineNumber": 3,

"startColumn": 77,

"endLineNumber": 3,

"endColumn": 90

}

当我参考网上办法往style=’‘前面加个：时

:style=’‘,这样确实可以正常编译,但是样式却失效了!

求解决这个报错的办法!!
