Tmux running - unsuccessful


why i can’t run tmux in console? it gives me a error like if i run tmux under tmux


because cloud9 uses tmux in console by default.
You can run export TMUX= as a workaround.
Could you describe what are you trying to do, that may help us to find a better solution.


in addition to JS development, I need C/C++ too,
so C9 doesn’t provide minimal C++ environment, but anyway vim with a plugins is enough.
however tmux should also be used in addition to vim. you see - cmake, profiling, some test scripts etc.

all this requires a consoles . locally tmux is preferable than a few terminal
