博主，IView UI自定义主题如何使用

[thanktiger]

博主，这是我的webpack配置
我在我的工程src下建立一个themes文件夹，里面有index.js ，index.less， purple.less， red.less
目前来说不太明白您的参数里面该如何修改，谢谢。

@thanktiger 建议是试一下 方法二
如果觉得麻烦的话 建议直接使用 webpack-multiple-themes-compile

[hiyangguo]

@thanktiger lessContent 改成你的内容。比如:

@import "../../index.less"

[thanktiger]

博主，改了lessContent的路径，保证是正确的，但是会报failed @import "../src/themes/index.less"

[hiyangguo]

@thanktiger 那应该是你的相对路径写错了
