FileNot创建错误:fluidsynth

Question

我只想用midi2audio把我的midi文件转换成mp3，我用的代码是：

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

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


---------- or

from midi2audio import FluidSynth

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

但是我得到了同样的结果：

----------

因此，我尝试将"fluidsynth“文件夹复制到"midi2audio"，但仍然不起作用。我已经安装了midi2audio和fluidsynth，谁知道发生了什么？

Answer 1

您必须将"fluidsynth“复制到PATH环境变量所指向的某个文件夹中(在终端应用程序中键入"echo $PATH”以查看实际注册的内容)。

在类unix系统上，python通常会发现fluidsynth位于/usr/bin/fluidsynth (路径中列出了/usr/bin )。在Os X上，事情没有太大的不同，任何文档都应该适合。一种常见的做法是使用/usr/local/bin文件夹添加自定义程序。

Answer 2

也许你应该先安装fluidsynth。

对于ubuntu：

sudo apt-get install fluidsynth
