事实证明,这个问题与使用过的样板有关。一种解决方法是不提取 TypeScript 文件,而是暂时将其保存在 .vue 文件中。
我在一个简单的 Vue 测试项目中遇到了这个错误:
ERROR Failed to compile with 1 errors
error in ./src/App.ts
Syntax Error: Unexpected token (11:7)
基本上就是你运行时得到的默认项目:
vue init Toilal/vue-webpack-template my-project
失败的具体代码:
@Component
export default class HelloWorld extends Vue {
@Prop({ default: 'default ToDo' })
todo: string; // unexpected token
name = "test9"; // fine
}
其他一切似乎都运行良好,我没有看到有人抱怨 ':' 在我寻找答案时是一个意外的标记。大约 2 年前,一个人遇到了这个问题,并通过使用新的 npm 版本解决了这个问题,但我显然是在一个从未有过的版本上。
这些是我的 package.json 中的依赖部分,因为我猜我的问题是一些奇怪的库组合?
