cannot be compiled under ‘--isolatedModules‘

'YHLogin.vue' cannot be compiled under '--isolatedModules' because it is considered a global script file. Add an import,export, or an empty 'export {}' statement to make it a module.

如上异常出自下方的 code 定义变量的时候抛出.大致理解为TS未能导出/导入的文件视为旧脚本的文件并非模块;

const handleOpen = (key: string, keyPath: string[]) => {
  console.log(key, keyPath);
};

解决办法

根据提示将 ts 配置文件 tsconfig.json 中添加或修改 isolatedModules 的值为 false 即可.

{"extends":"@vue/tsconfig/tsconfig.web.json","include":["env.d.ts","src/**/*","src/**/*.vue"],"compilerOptions":{"baseUrl":".","paths":{"@/*":["./src/*"]},"isolatedModules":false,// 添加或修改该属性即可},"references":[{"path":"./tsconfig.config.json"}]}
