我试图在我的Linux笔记本电脑上安装MuJoCo，一切都正常，直到我尝试将它导入Python文件时出现问题。当我尝试导入或运行已包含MuJoCo的Python脚本时，会出现以下错误：

Import error. Trying to rebuild mujoco_py.

我已安装gcc 11.0.2，并在虚拟环境中使用python3.8。以下是我的详细步骤：https://docs.google.com/document/d/1eBvfKoczKmImUgoGMbqypODBXmI1bD91/edit

一切正常，直到我尝试运行实际的Python模块时，出现了问题。

我真的不知道为什么会发生这种情况，我已经尝试了互联网上的所有方法。如果有人能帮忙，我会非常感激。

“安装Mujuco”是什么意思？在Linux上，可以通过编译和构建源代码或安装Linux发行版的预编译和预构建软件包来安装某些东西。试图从任何地方下载一些随机二进制文件总是会以失败告终。 - Sam Varshavchik

我已经尝试了互联网上的几乎所有方法。大多数你在互联网上找到的东西都没有用，有些甚至很恶心。 - user4581301

嗨，当我说安装mujuco时，我指的是按照这些确切的步骤并尝试安装其软件包https://github.com/openai/mujoco-py。 - danielliucs

“下载二进制文件”？基本上就是这样了，请查看我的第一条评论。不要相信互联网上的所有内容。除非您的Linux发行版与用于构建这些二进制文件的完全相同，否则这将以泪水告终。您需要返回mujoco的源代码，并直接从源代码构建它。 - Sam Varshavchik

/home/daniel/miniconda3/envs/mujoco_py/lib/libstdc++.so.6是从哪里来的？某些软件捆绑了一个比您系统版本旧的libstdc++.so.6版本，而其他系统库依赖于更新的版本。您可以通过删除您家目录中的文件来解决此问题。
