First, I running Cloud9 on Docker (using with linuxserver/cloud9) on Raspbian and installed build-essential on Cloud9
When I tried to run C code (such as printing hello world), it says
Compiling /code/first_c.c ...
cc first_c.c -o first_c
bash: line 6: node: command not found
Process exited with code: 127
Should I install something more? or how can I solve it?
If you just want to run C code, you don't need node, but you have to first install gcc by opening a terminal and running:
sudo apt update && sudo apt install gcc
Then check that your runner is C (simple) and that you have uncheck the icon Run in debug mode.
If you want to run in debug mode you have to install node and gdb with:
sudo apt install nodejs gdb
== Update ==
P.S.: When gdb is not installed, C9 shows wrongly :
"gdbserver" is not installed
This is a bug: corrected by this (yet) non-merged PR.
