[Gradio]"ModuleNotFoundError: No module named 'ffmpy'"

这篇文章我们来一起聊聊嵌入版python无法安装ffmpy（Gradio依赖）的问题

嵌入式的python虽然也是python，也能跑程序

但是作为给嵌入式系统用的免安装的环境肯定有点东西不一样，而且少了一堆内置模块

从报错内容来，问题出现在这一行

from ffmpy import __version__

具体为什么炸了，只能说是嵌入式的版本差异问题了，安装版的就没有这个毛病

解决方法也很简单

下载模块的源码包到本地，然后修改setup.py

源码包在这下：https://pypi.org/project/ffmpy/#files

加上这两行

import sys
sys.path.append('.')

此时你的setup.py看起来大概是这么个样子，注意插入上面两行的位置

from setuptools import setup
from setuptools.command.test import test as TestCommand  # noqa
import sys
sys.path.append('.')
from ffmpy import __version__

setup(
    name="ffmpy",
    version=__version__,
    description="A simple Python wrapper for ffmpeg",
    long_description=open("README.rst").read(),
    author="Andrii Yurchuk",
    author_email="[email protected]",
    license="MIT",
    url="https://github.com/Ch00k/ffmpy",
    py_modules=["ffmpy"],
    classifiers=[
        "Topic :: Multimedia :: Sound/Audio",
        "Development Status :: 4 - Beta",
        "Intended Audience :: Developers",
        "License :: OSI Approved :: MIT License",
        "Natural Language :: English",
        "Programming Language :: Python :: 3",
        "Programming Language :: Python :: 3.6",
        "Programming Language :: Python :: 3.7",
        "Programming Language :: Python :: 3.8",
        "Programming Language :: Python :: 3.9",
        "Programming Language :: Python :: 3.10",
        "Programming Language :: Python :: 3.11",
        "Programming Language :: Python :: 3.12",
        "Programming Language :: Python :: Implementation :: CPython",
        "Programming Language :: Python :: Implementation :: PyPy",
        "Operating System :: Microsoft :: Windows",
        "Operating System :: POSIX",
        "Operating System :: POSIX :: BSD",
        "Operating System :: POSIX :: Linux",
        "Operating System :: MacOS :: MacOS X",
    ],
    keywords="ffmpeg ffprobe wrapper audio video transcoding",
)

然后，在和setup.py的同级目录下，执行这行

python setup.py

然后就装上去了，此时应该可以继续通过pip安装gradio了
