错误提示：

Error building Player: UnityException: Bundle Identifier has not been set up correctly
Please set the Bundle Identifier in the Player Settings. The value must follow the convention 'com.YourCompanyName.YourProductName' and can contain alphanumeric characters and underscore.
Each segment must not start with a numeric character or underscore.

根据提示我们知道需要设置Bundle Identifier。

打开File=>build settings => player settings=>属性面板找到Bundle Identifier  设置下名称，格式为：com.YourCompanyName.YourProductName

设置好重新发布即可
