I’ve got the same problem (macOS Mojave, python 3.6.x) with moviepy 1.0.1 but I’ve managed to work around it downgrading it to 1.0.0.

Hope it helps.

pip install moviepy==1.0.0

bug fixed!

@Ethan0429 So here are the steps:

Make sure you upgrade to version 1.0.1
go to the moviepy directory (you need to adjust for your python version): cd /usr/local/lib/python3.7/dist-packages/moviepy/
edit the AudioFileClip class at line 93, e.g. with vim: vim audio/io/AudioFileClip.py +93
comment these lines (add an # in front of them): # def __del__(self): # self.close()
save and exit the editor

And you should be done.

Could you please confirm if this works for you? Cheers

PS: I’ve put it quite detailed to potentially assist other people. 😃

This one surprisingly working solution to the issue. Thanks @dcaravana ✌. It’s really under my estimation to think of downgrading can be a solution!

Fixed in #1185 and version 1.0.3. Thank you everyone for your patience! Use `pip install moviepy --upgrade`` to update to the latest version.

Hey all! This is obviously a problem that needs sorting. It has built up over time with people making quick fixes to small parts of the code without taking into consideration that the same methods should be applied consistently to all of moviepy, and also that different operating systems handle resources differently. Around eastertime I intend to have a proper look at it across different OSs and hopefully come up with a solution that works for everyone.

Same issue. Python 3.7. None of the solutions above worked.

After trying multiple times, I can confirm that the solution also works for 1.0.2.

@Ethan0429 So here are the steps:
1. Make sure you upgrade to version 1.0.1

2. go to the moviepy directory (you need to adjust for your python version):
   `cd /usr/local/lib/python3.7/dist-packages/moviepy/`

3. edit the AudioFileClip class at line 93, e.g. with vim: `vim audio/io/AudioFileClip.py +93`

4. comment these lines (add an `#` in front of them):
   `#    def __del__(self):`
   `#        self.close()`

5. save and exit the editor
And you should be done.

Could you please confirm if this works for you? Cheers

However I am getting “OSError: [WinError 6] The handle is invalid” errors. I added “clip.reader.close()”, but this did not solve the problem. After a couple of runs, the error would occur again, and I had to restart my IDE. I suppose this is an unrelated issue.

Thank you @sebasi it worked for me perfectly.

Same problem on OSX high sierra, python 3.6. Downgrade to 1.0.0 fixes issue.

osfa on Oct 9, 2019

Changed to v1.0.0 and it gives no error. Thanks guys

Furanyl on Oct 9, 2019

I changed to v1.0.0, and it works well.

@mraduldubey I believe you meant to tag @kaiqueocanha. I was trying to overlay text, not concatenate multiple videos into one.
