SubConverter文件IO异常 - 音乐21展示()

Question

我刚安装了music21，我正试着开始安装。我已经安装了Musescore3，但无法使show（）函数正常工作。你知道吗

我试着改变路径，遵循我在网上找到的一些指示，但没有效果

from music21 import *

us = environment.UserSettings()
us['musicxmlPath'] = 'D:\\Program Files\\MuseScore 3\\bin\\Musescore3.exe'
us['musicxmlPath'] = 'D:\\Program Files\\MuseScore 3\\bin\\Musescore3.exe'

我想做一个简单的节目（）

from music21 import *

f = note.Note('F5')
f.show()

我的错误是：

SubConverterFileIOException: png file of xml not found. Or file >999 pages?

Answer 1

我遇到过这种情况，因为在jupyter上运行时不能使用muscore3。 试着用终端运行它可以工作

Answer 2

当路径中有空格时，有时会出现错误请尝试将文件夹“Projeto Python-Música”重命名为“Python Musica”（同时删除重音以确保unicode不是问题所在），然后看看它是否解决了问题。你知道吗
