he intentado de todo, pero instalar firebase no he podido, incluso busque respuestas por horas en foros y nada 😕 <code>&lt;code&gt; ERROR...

Para solucionar el error se debe correr este comando

npm i firebase@7.24.0 

y agregar en el tsconfig al final esto

“esModuleInterop”: true,
“allowSyntheticDefaultImports”: true

asi como lo muestro a continuación
