The latest version of the WeChat web developer tool requires an APPID and a test number will be provided. However, if the tabBar is configured like yours, the homepage and logs will not be displayed. Do I need to download the same version as you?
Go and download a small program development tool yourself. There will be a custom appid button on it, which can be used during the development and testing phase!

I mean, it's downloaded, but the tabbar doesn't appear in the emulator
