这个问题貌似是python不能正确读取字符串
解决办法是打开C:\Anaconda3\lib\site-packages\matplotlib\font_manager.py文件,查找winreg.EnumValue,你会看到这样的代码
key, direc, any = winreg.EnumValue( local, j)
if not is_string_like(direc):
continue
if not os.path.dirname(direc):
direc = os.path.join(directory, direc)
direc = os.path.abspath(direc).lower()
将其替换成
key, direc, any = winreg.EnumValue( local, j)
if not is_string_like(direc):
continue
if not os.path.dirname(direc):
direc = os.path.join(directory, direc)
direc = direc.split('\0', 1)[0]
这样就可以画图了
