Estoy intentando instalar node-sass v3.7.0 ejecutando npm install node-sass@3.7.0 . La instalación parece estar funcionando al principio, y luego recibo este volcado repetidamente:

Recibo este volcado de arriba de forma consecutiva muchas veces. Al final, se devuelve este mensaje:

 + node-sass@3.7.0 added 21 packages from 43 contributors and audited 2105 packages in 121.004s`

Parece que se instaló. Pero cuando trato de usar mi aplicación, obtengo errores de node-sass y npm list -g node-sass indica que el paquete no está instalado. Vuelve:

 npm info it worked if it ends with ok npm info using npm@6.4.1 npm info using node@v8.15.0 /Users/wvn179/.nvm/versions/node/v8.15.0/lib └── (empty)

¿Qué es este problema? ¿Cómo puedo instalar node-sass con éxito?
