我正试图根据官方指示安装CVAT的开发版本，但在要求。txt应用的步骤中挣扎:
pip install -r cvat/requirements/development.txt
…出现以下错误:

我已经尝试了建议的修复，但没有运气:https://github.com/openvinotoolkit/cvat/issues/4406
环境:
- MacBook Pro (Intel x64) macOS Monterey (Version 12.4)
- (pyenv) Python 3.9.10
还有哪些选项可以用来修复它?
就在上周遇到了同样的问题。我想说的问题是，你试图安装PyAv没有适当的动态库从FFMPEG。PyAv只是一堆Python绑定，用于连接系统中的二进制动态库。我也假设你使用的是Ubuntu 18.04。标准存储库上最新的FFMPEG版本不好，是3.x。
你需要编译一些等于或高于4.0的FFMPEG版本。为此，您需要从源代码编译FFMPEG，使用make和make install编译并安装它。或者你可以添加一个存储库,你想要的二进制文件。我自己编译了它，它生成了我需要的所有库，所以这就是我在这里描述的。
首先在终端上运行ffmpeg，以确保您的FFMPEG版本低于4.0。如果是这种情况，运行以下命令。他们将下载源代码、解压缩、编译并安装文件。之后，PyAv的Python绑定应该会找到正确的库，并且安装将能够继续进行。
确保您有依赖项:
sudo apt install yasm libvpx. libx264. cmake libavdevice-dev libavfilter-dev libopus-dev libvpx-dev pkg-config libsrtp2-dev libpython3-dev python3-numpy
然后下载源码:
curl https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/ffmpeg/7:4.2.4-1ubuntu0.1/ffmpeg_4.2.4.orig.tar.xz --output ffmpeg_4.2.4
解压文件:
tar -xf ffmpeg_4.2.4.orig.tar.xz
目录:
cd ffmpeg-4.2.4/
编译并安装文件:
./configure --disable-static --enable-shared --disable-doc
make
sudo make install
sudo ldconfig
它现在应该编译和安装FFMPEG 4.2.4的动态库。完成后，打开NEW终端，并输入ffmpeg来验证一个新的4。X版本现在可用。然后尝试再次安装CVAT，它现在应该工作了。
