【问题描述】：

我在安装 mujoco 时遇到了麻烦。

我按照https://github.com/openai/mujoco-py/issues/253 的步骤进行操作。

一切正常，但是当我不得不运行“python examples\body_interaction.py”时，我遇到了问题：

Traceback (most recent call last):
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\mujoco-py\examples\body_interaction.py", line 10, in <module>
    from mujoco_py import load_model_from_xml, MjSim, MjViewer
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\__init__.py", line 2, in <module>
    init_config()
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\venv\lib\site-packages\mujoco_py\config.py", line 37, in init_config
    raise error.MujocoDependencyError('Found your MuJoCo license key but not binaries. Please put your binaries into ~/.mujoco/mjpro131 or set MUJOCO_PY_MJPRO_PATH. Follow the instructions on https://github.com/openai/mujoco-py for
 setup.')
mujoco_py.error.MujocoDependencyError: Found your MuJoCo license key but not binaries. Please put your binaries into ~/.mujoco/mjpro131 or set MUJOCO_PY_MJPRO_PATH. Follow the instructions on https://github.com/openai/mujoco-py for

这就是我的 .mujoco 目录的样子：

mujoco200 是我从那里下载的目录：https://www.roboti.us/index.html for win64，

这就是我的 Env 变量的样子：

为了解决这个问题，我尝试从there 下载“mjpro131 win64”，并将其添加到环境中。使用名称“MUJOCO_PY_MJPRO_PATH”的变量，但它给了我另一个错误：

Traceback (most recent call last):

    mjlib = cdll.LoadLibrary(os.path.abspath(libfile))

    return self._dlltype(name)
  File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\ctypes\__init__.py", line 374, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 n’est pas une application Win32 valide

最后一行翻译：

OSError: [WinError 193] %1 Is not a valid win32 application.

我也尝试过使用 win32 存档，但它给了我完全相同的错误。

【解决方案1】：

我在 Linux 中遇到了同样的问题。我决定下载0.5.7版本的mujoco

pip install mujoco-py==0.5.7

然后将需求改为

click==7.0
xmltodict==0.12.0
scipy==1.3.1
gym==0.10.8
jsonnet==0.11.2
numpy
mujoco-py==0.5.7
