AttributeError: 'FFmpegWriter' object has no attribute '_proc'

I have some problem which i cannot find answer to. After installing scikit-video and FFmpeg i got this error:

AttributeError: 'FFmpegWriter' object has no attribute '_proc'

can you help me to find solution to this.

from skvideo.io import FFmpegWriter

def main():
    ...
    video_writer = FFmpegWriter('video.mp4')
    ...
if __name__ == '__main__':
    main()

Already tried to install pyaudio, reinstall FFmpeg and skvideo and install different versions of packages. Does not help at all.

Edit: an example of the full traceback resulting from /skvideo/io/abstract.py is below.

Traceback (most recent call last):
File "run_modules.py", line 93, in <module>
    Pipeline.create_videos(video_attr, args.output_path, args.padded)
File "/home/leuko/.local/lib/python3.6/site-packages/skvideo/io/abstract.py", line 474, in close
    if self._proc is None:  # pragma: no cover
AttributeError: 'FFmpegWriter' object has no attribute '_proc'

I just ran into this issue, and found that FFmpegWriter was actually masking another error. My code was roughly like this:

    with FFmpegWriter('/tmp/tmp.webm') as writer:
        for frame in frames:
            <code to generate out>
            writer.writeFrame(out)

The code block before writer.writeFrame was raising an error, but I didn't see that because I didn't look at the full stack trace. I couldn't figure out why FFmpegWriter was throwing this error, but it made sense once I realized I wasn't actually writing any frames but was then trying to close the writer.
