1、在安装好[email protected] 以后,首先安装sass-loader
- npm i sass-loader node-sass -D
2、安装element-theme
- npm i element-theme -D
3、安装theme-chalk
- npm i element-theme-chalk -D
- # or from github
- npm i https://github.com/ElementUI/theme-chalk -D
4、初始化变量文件
- et -i // 默认的文件是element-variables.scss,也可以自定义文件名 et --init [file path]
安装成功以后,在项目里会自动生成一个element-variables.scss 文件,如下图:
里面定义的是所有的颜色变量
当然,这一步也有可能失败,命令行提示找不到et 这个命令。这个时候需要按照步骤一,重新装一下sass-loader
5、修改变量
直接编辑 element-variables.scss 文件,例如修改主题色为红色
6、编译主题
保存文件后,到命令行里执行 et 编译主题,如果你想启用 watch 模式,实时编译主题,增加 -w 参数;如果你在初始化时指定了自定义变量文件,则需要增加 -c 参数,并带上你的变量文件名
此时,项目中会自动生成一个theme文件夹,里面是编译后所有的字体文件和样式文件
7、引入自定义主题
默认情况下编译的主题目录是放在 ./theme 下,你可以通过 -o 参数指定打包目录。像引入默认主题一样,在代码里直接引用 theme/index.css 文件即可。
- import '../theme/index.css'
- import ElementUI from 'element-ui'
- import Vue from 'vue'
- Vue.use(ElementUI)
启动项目,会发现原来默认的蓝色会变成红色
官网提供的这种方法仅适用于一次性的更改全局主题颜色,如果想实现官网2.0版本右上角,使用 ColorPicker 颜色选择器 动态换肤。那么建议参考vue-element-admin,作者的 《手摸手,带你用vue撸后台》系列文章非常精彩
