Before I decide to buy a Raspberry pi I want to preview it on my old computer.
I installed Raspberry pi (desktop version from homepage of Raspberry).
Everything was fine, When I install nodejs from apt source package, it doesn’t have alias (syntax for npm). Then I followed others topic, they said check uname -a and go to nodejs homepage to download a compatible version.

Here is my $uname -a Linux raspberry 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
Then I go to node homepage and download a version of Linux Binaries (ARM) V6 unpacked and copy all of them to /usr/local/ and checked it with command node -v &npm -v. I got this error messages /lib/ld-linux-armhf.so.3: No such file or directory.

I thought that was my computer is not compatible but when I tried it on virtualbox I still got same problem.
I need your help. Thanks.
