typescript中使用类并且声明成员变量后，在UC浏览器中运行会报 Unexpected token = 错误

处理方式

lib中的esnext改成ES2015，增加target:ES2015

{"extends": "@vue/tsconfig/tsconfig.json","compilerOptions": {"target": "ES2015","sourceMap": true,"baseUrl": ".","paths": {"@/*": ["./src/*"]},"lib": ["ES2015", "dom"],"types": ["@dcloudio/types"]},"include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"]
}
