An installation issue

[DISCORDzzz]

• hi, I create my conda env as required in instructions, which is python=3.7. when I tried to install habitat-sim, I got several issues. One of them is that when running python setup.py install --bullet --headless , there is issue said :

CMake Error: Error: generator : Ninja Does not match the generator used previously: Unix Makefiles Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.
