使用vue-cli3构建后，自定义color，引用theme和colors报错

[tkgkn]

package.json 如下

{
  "name": "atool",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "dev": "yarn serve"
  },
  "dependencies": {
    "core-js": "^2.6.5",
    "muse-ui": "^3.0.2",
    "vue": "^2.6.10",
    "vue-class-component": "^7.0.2",
    "vue-property-decorator": "^8.1.0",
    "vue-router": "^3.0.3",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^3.8.0",
    "@vue/cli-plugin-eslint": "^3.8.0",
    "@vue/cli-plugin-typescript": "^3.8.0",
    "@vue/cli-service": "^3.8.0",
    "@vue/eslint-config-prettier": "^4.0.1",
    "@vue/eslint-config-typescript": "^4.0.0",
    "babel-eslint": "^10.0.1",
    "babel-plugin-import": "^1.12.0",
    "eslint": "^5.16.0",
    "eslint-plugin-vue": "^5.0.0",
    "less": "^3.0.4",
    "less-loader": "^4.1.0",
    "typescript": "^3.4.3",
    "vue-template-compiler": "^2.6.10"
  }
}

但是看muse-ui的types中，index.d.ts已经声明了模块啊。是不是ts版本问题？
