Cannot run any code on Mac OS X High Sierra

The experiment programs I edited before I upgrade my Mac to High Sierra cannot run now. Even when I run the demo, Psychopy give me the same feedback.Here is the traceback.
Can somebody help me out?

Traceback (most recent call last):
File “/Applications/”, line 2142, in compileScript
File “StringIO.pyc”, line 271, in getvalue
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe4 in position 132: ordinal not in range(128)
