运行时出错:
from music21 import *
n1 = note.Note('C4', quarterLength=1)
n2 = note.Note('A4', quarterLength=1)
s = stream.Stream()
s.append(n1)
s.append(n2)
s.show('lily.svg')
Traceback (most recent call last):

versionString = versionString.split()[-1]
IndexError: list index out of range
我已经安装了scipy和mathplotlib,所以music21不再抱怨它们不可用了。 我在Windows 7上运行Python 3.4。
如果我使用s.show('musicxml.png')
来获取我的图片,我会收到错误:
Traceback (most recent call last):
File "C:\Python34\test.py", line 7, in <module>
s.show('musicxml.png')

elif not os.path.exists(musescoreFile):
File "C:\Python34\lib\genericpath.py", line 19, in exists
os.stat(path)
TypeError: stat: can't specify None for path argument
我需要做些什么来获取图像(最好是svg)?

<强> LilyPond的强>
我有同样的错误。我已经设法通过以下方式为music21配置LilyPond:
C:\Program Files (x86)\LilyPond\usr\bin
到C:\LilyPond\usr\bin
)。
我在music21代码中看到,在执行lilypond命令时,它没有在路径周围放置必要的配额,所以必须以这种方式解决问题。Created configuration file in music21 and set lilypondPath
us = environment.UserSettings()
us.create()
us['lilypondPath'] = 'C:/LilyPond/usr/bin/lilypond.exe'
你可以检查它是否设置正确:
print us['lilypondPath']
嗯,这可能没有必要,但在我尝试的过程中,我重复了几次,所以如果一切都不能立即起作用,你可以在最后尝试。
<强> MUSESCORE 强>
添加两次musescore路径到环境(找到这种设置环境变量的新方法),一次为"musescoreDirectPNGPath"
:
environment.set("musescoreDirectPNGPath", "C:/MuseScore2/bin/MuseScore.exe")
然后是"musicxmlPath"
:
environment.set("musicxmlPath", "C:/MuseScore2/bin/MuseScore.exe")
经过几次尝试,调试等后,我了解到如果我们想使用Musescore,传入文件名“.xml”扩展名而不是“.png”非常重要:
stream_name.show( 'musicalxml.xml')
Musescore无法打开.png文件,但可以打开.xml文件。
最后,我可以添加一些生成文件的代码,而无需打开lilypond或musescore。希望有人发现它有用
LilyPond的:
# music21object - stream or score or any object that can be showed
conv = music21.converter.subConverters.ConverterLilypond()
scorename = 'myScoreName'
filepath = 'C:/path/to/musical_scores/' + scorename
conv.write(music21object, fmt = 'lilypond', fp=filepath, subformats = ['pdf'])
MUSESCORE:
from music21.converter.subConverters import ConverterMusicXML
conv_musicxml = ConverterMusicXML()
scorename = 'myScoreName.xml'
filepath = 'C:/path/to/musical_scores/' + scorename
out_filepath = conv_musicxml.write(music21object, 'musicxml', fp=filepath, subformats=['png'])
请注意,该得分名称的扩展名为“.xml”。
不幸的是,它不会将文件保存在指定的文件路径中。 Musescore将“-1”添加到文件名,但是可以获得这个更改的文件路径(在上面的代码中作为out_filepath)并稍后重命名为我们想要的。
答案 1 :(得分:0)
我能够使用带空格的路径设置musescore。最重要的是确保使用倒斜线。我就这样做了:
# Create the user environment for music21
us = m21.environment.UserSettings()
us['musicxmlPath'] = 'C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe'
us['musescoreDirectPNGPath'] = 'C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe'
希望它有所帮助!
