Source Problem in React Native

I’m having a load problem with React On, I’ve installed both fonts for my project and it was working fine until I stopped working for a while because of another error. When I returned to try to resolve it these two messages appeared. I tried to resolve them by downloading again with the command npm install and it hasn’t. Could someone/could help me? Follow the mistakes:

fontFamily "Ubuntu_700Bold" is not a system font and has not been loaded through Font.loadAsync.

- If you intended to use a system font, make sure you typed the name correctly and that it is supported by your device operating system.

- If this is a custom font, be sure to load it with Font.loadAsync.

Try the commands:

rm -rf node_modules/ && rm -f package-lock.json && rm -f yarn.lock && npm cache verify && npm install && expo r -c

I ran the specified commands to clear the cache, but to no avail.

In sequence:

Change the expo version in the package.json file to 36.0.1 and execute the npm install.
Change the expo version again to the previous one, 37.0.3 and perform npm install.

This last step solved.

All I had to do was execute the command:

rm -rf node_modules/ && rm -f package-lock.json && rm -f yarn.lock && npm cache verify && npm install && expo r -c
