Tengo un problema con la instalación de dependencias en mi proyecto simple de node.js, cuando lanzo yarn add express command y luego la consola me arroja este error:

 C:\Users\...\Desktop\npm-test>yarn add express yarn add v1.22.4 [1/4] Resolving packages... info There appears to be trouble with your network connection. Retrying... info There appears to be trouble with your network connection. Retrying... info There appears to be trouble with your network connection.

¿Alguien puede decirme qué está mal? ¡Gracias por cualquier ayuda!
