错误：无法为opencv-python构建轮子，在anaconda env中安装gym时需要安装基于pyproject.toml的项目

问题描述 投票：0回答：1

我正在阅读《SUDHARSAN RAVICHANDIRAN - 使用Python进行强化学习 - _掌握强化和深度强化》书中的一章。有一个在单独的 anaconda 环境中使用 Gym 工具包的动手练习。在那里，我必须按照几个步骤在我的 Xubuntu 机器上安装必要的工具。

打开终端并输入以下命令来下载 Anaconda：
    wget https://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh
  1. 下载后，我们可以使用以下命令安装Anaconda：
    2. bash Anaconda3-5.0.1-Linux-x86_64.sh
  2. 使用以下命令创建虚拟环境并将我们的环境命名为 Universe：
    3. conda create --name universe python=3.6 anaconda
  3. 激活它：
    4. source activate universe
  4. 安装以下依赖项：
    5. 

  5. 

    6. sudo apt-get update
sudo apt-get install golang libcupti-dev libjpeg-turbo8-dev make tmux
htop chromium-browser git cmake zlib1g-dev libjpeg-dev xvfb libav-tools
xorg-dev python-opengl libboost-all-dev libsdl2-dev swig
conda install pip six libgcc swig
conda install opencv 



安装健身房：
    pip install gym==0.15.4
  1. 

    2. 然后花了相当长的时间并给出了以下日志

请考虑我必须对上述命令进行一些修改，因为最后一个版本是 4 年后的版本，并且某些命令不起作用。即：




    libav-tools
  •  已替换为 
    ffmpeg
    ，
    python-opengl
     已替换为 
    PyOpenGL
    

    • sudo apt-get install ffmpeg
sudo apt-get install python3-pip
pip3 install PyOpenGL
sudo apt-get install ffmpeg



我遵循了
stackoverflow线程
，但没有任何补救措施。

 所评论的那样，我运行了 pip install --only-binary ":all:" opencv-python 并在 anaconda 环境中安装了 
gym
。然后我得到以下日志：

    Uninstalling cloudpickle-1.5.0:
      Successfully uninstalled cloudpickle-1.5.0
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.1.4 requires pyqt5<5.13; python_version >= "3", which is not installed.
spyder 4.1.4 requires pyqtwebengine<5.13; python_version >= "3", which is not installed.
distributed 2.20.0 requires cloudpickle>=1.3.0, but you have cloudpickle 1.2.2 which is incompatible.



根据我运行的不兼容性：
pip install pyqt5==5.12.3 pyqtwebengine==5.12.1

之后我运行
pip install gym==0.15.4
并且没有错误！
