Can't install npm and project doesn't take my modif


I really have been getting an issue on my project. I can’t install npm because i’ve been getting this error : npm WARN tar ENOSPC: no space left on device, write
Actually, i’m having 2GB as storage and only, 14MB are used.

Another issue, my project doesn’t take any modifications : always reconnecting and delete it.
Can you help me plz ?
