Question

我尝试安装Python包music21，并且在Windows中运行它时遇到问题。基本上，当我尝试运行简单命令时，他们给出了一个例子

converter.parse("tinynotation: 3/4 c4 d8 f g16 a g f#").show()

我收到了错误

SubConverterException: Cannot find a path to the 'mscore' file at C:\Program Files (x86)\MuseScore 2\MuseScore.exe -- download MuseScore

原因是因为Musescore.exe不再存储在文件夹＆＃34; MuseScore 2＆＃34;但现在在一个名为＆＃34; bin＆＃34;的子文件夹中。所以路径需要设置为＆＃34; C：\ Program Files（x86）\ MuseScore 2 \ bin \ MuseScore.exe＆＃34;为了访问Musescore。

如何更改此内容？

完全错误

SubConverterException: Cannot find a path to the 'mscore' file at C:\Program Files (x86)\MuseScore 2\MuseScore.exe -- download MuseScore

Answer 1

导入music21后立即执行此操作：

environment.set('musescoreDirectPNGPath', 'C:\\Program Files (x86)\\MuseScore 2\\bin\\MuseScore.exe')

Python - 如何在包music21中重命名Musescore路径？
