Why is react-native link not working?

Question

Android

I have been studying react-native for a week now. 3 days of which I just tried to install google authentication and a video stream player, today I decided to install react-native-sensors. Everything had to be installed manually because the react-native link didn't work (wanted me to write package in androidManifest.xml). 1 time I was able to normally write a module there and run the command, but for this I needed to know com.(...) . I went to github, there are not the instructions for installing the module. I think: maybe I'm stupid, I'll go look on stackoverflow, and they write install the module and write the command react-native link dependency-name. Well, it doesn’t work, in the console it writes to write to the manifest

react-native link react-native-sensors

rnpm-install ERR! ERRPACKAGEJSON No package found. Are you sure this is a React Native project?

Package name not found in Z:\phone-app\android\app\src\debug\AndroidManifest.xml

What should I do to make everything work properly? For the 3rd day I just sit and try to install the modules I need, which simply do not work at the end. I will be glad to all answers. ATP in advance
