How can I get path of cocos? I've run find cocos2d -name '*.h' -o -name '*.hpp' | xargs -L1 dirname | uniq but failed...

Or I fond

export COCOS_CONSOLE_ROOT=xxxxx
export PATH=$COCOS_CONSOLE_ROOT:$PATH

In my .zshrc can I use it? And how to use It... I'm quite not familiar with python...

I solve this problem. Thanks.

@yszheda This is awesome, you rock 👍
