我刚刚安装了music21，我正在尝试开始使用它。我安装了 Musecore3，但我无法使 show() 函数工作。

我已经尝试更改路径，按照我在网上找到的一些说明，但无济于事


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'

我正在尝试做一个简单的 show()

from music21 import *

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

这是我得到的错误：

有时当路径中有空格时会出现错误 - 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）并查看是否解决事物。

我遇到过这种情况，因为在jupyter上运行时不能使用Musscore3。尝试使用终端运行它可以工作
