NodeJS - npm: zlib binding closed

Question

I am using normal NodeJS with npm, but for two days now every time that I want to install a package by 'npm install xxx', get the error:
npm ERR! zlib: zlib binding closed
I am sure that I have the right to write/read in the target folder.
Can you help me?
Thanks in advance
