脚本从 PyCharm 开始时出现 FileNotFoundError

Question

我正在使用 pydub 将 mp3 文件转换为 wav。我从 Atom 切换到 PyCharm，现在抛出以下错误。

C:\Users\BlakkM9\AppData\Local\Programs\Python\Python37\lib\site-packages\pydub\utils.py:193: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
  warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)

    startupinfo)
FileNotFoundError: [WinError 2] Das System kann die angegebene Datei nicht finden

在切换之前，我只是在项目的根目录中时在 PowerShell 中键入 python start.py。这仍然可以正常工作。

对应代码：

from pydub import AudioSegment

AudioSegment.converter = os.path.dirname(os.path.abspath(__file__)) + "\ffmpeg\bin\ffmpeg"

current = AudioSegment.from_mp3("./rec/ready.mp3")
current.export("./rec/current.wav", format="wav")

PyCharm 中的启动选项

谢谢

编辑：

使用 mp3 文件的绝对路径也不起作用（即使当我用上面两行 open(...) 测试它时它起作用了。

打印 AudioSegment.converter 在 PyCharm 和 PowerShell 中也是一样的。

我现在通过自己实施解决了我的问题。不知道出了什么问题。使用代码需要您自担风险，因为我是 python.

的新手

import os
import subprocess

curr_path = os.path.abspath(".")

def ffmpeg(input_file, output_file):
    # convert to absolute paths if necessary
    if os.path.isabs(input_file):
        input_path = input_file
    else:
        input_path = curr_path + input_file

    if os.path.isabs(output_file):
        output_path = output_file
    else:
        output_path = curr_path + output_file

    subprocess.check_call(curr_path + "/ffmpeg/bin/ffmpeg.exe -i " +
                          input_path + " " +
                          output_path,
                          stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)

ffmpeg输出被禁用，如果不改变ffmpeg文件夹需要和函数所在的脚本放在同一个目录下。
