Question

我只想使用midi2audio将我的midi文件转换为mp3，我使用此代码：

----------
from midi2audio import FluidSynth

FluidSynth().midi_to_audio('test.mid','test.mp3')


---------- or

from midi2audio import FluidSynth

FluidSynth().play_midi('test.mid')

但我得到了同样的结果：

----------


/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 /Users/blake/Desktop/Bsmart_music/test/t_p/1.py
Traceback (most recent call last):

所以，我试着复制折叠＆＃34; fluidynth＆＃34;到＆＃34; midi2audio＆＃34;，但它仍然无法运作。我已经安装了midi2audio和fluidsynth，谁知道发生了什么？

Answer 1

您必须在PATH环境变量指向的某个文件夹中复制“fluidsynth” （在终端应用中键入“echo $ PATH”以查看实际注册的内容）。

在类似unix的系统上，python通常会找到位于/ usr / bin / fluidsynth的fluidynth（因为/ usr / bin在PATH中列出）。在Os X上，任何文档都应该适合的东西并没有太大的不同。通常的做法是使用/ usr / local / bin文件夹添加自定义程序。

Answer 2

也许您应该先安装Fluidsynth

对于Ubuntu：

sudo apt-get install fluidsynth

FileNot FoundError：fluidsynth
