typescript decorator报错

Question

TypeScript decorator reports “Unable to resolve signature of class decorator when called as an expression”

同样的两段代码，同样的vue-property-decorator，编译器报错。不清楚是我哪里有问题？

  "dependencies": {
    "vue": "^2.5.2",
    "vue-class-component": "^6.0.0",
    "vue-property-decorator": "^6.0.0",
    "vue-router": "^3.0.1"
  },
  "devDependencies": {
    "css-loader": "^0.28.1",
    "ts-loader": "^2.0.3",
    "typescript": "^2.3.2",
    "vue-loader": "^12.0.3",
    "vue-template-compiler": "^2.5.2",
    "webpack": "^2.5.0"
  }

Answer 1

是不是两段代码导入的Component并不是同一个，注意到你的两个import语句其实是不同的。

Answer 2

跟 Component 本身没关系，是引入了其他非ts兼容的组件导致的。
