I tryed to re install it again and now I have:
./configure
Node.js configure error: No acceptable C compiler found!
Please make sure you have a C compiler installed on your system and/or
consider adjusting the CC environment variable if you installed
it in a non-standard prefix.
I start with a fresh Rpi.
I solved it by: sudo apt-get install gcc g++ git
and aslo sudo apt-get install python for the ./configure
