Pip install fails to install PsychoPy with PyCharm

#1

Sorry for asking silly questions. I thought changing to PsychoPy 3 would also a good point changing to PyCharm (replacing spyder). I used pip install psychopy from within PyCharm which immediately collected all necessary packages including the dependencies (great!). Almost all stuff got installed, however, not PsychoPy. Below is what I get. Any suggestions?

Installing collected packages: greenlet, gevent, msgpack, msgpack-numpy, msgpack-python, psutil, pbr, mock, numexpr, tables, pyzmq, decorator, tqdm, proglog, imageio, imageio-ffmpeg, moviepy, opencv-python, python-gitlab, smmap2, gitdb2, gitpython, wheel, astunparse, esprima, freetype-py, wxPython, pyobjc-core, pyobjc-framework-Cocoa, pyobjc-framework-Quartz, PyQt5-sip, pyqt5, psychopy
