Ubuntu中mujoco210 mujoco_py D4RL安装及错误解决

本文根据一篇知乎文章链接在此进行配置，记录在配置过程中遇到的一些问题，原文作者的教程很详细，在此对原作者表示感谢～

直接进行知乎原文的第2.2 有效安装过程(避坑)

2.注意上文中各行代码的作用
原文作者的代码有一点点小问题，我在注释中指出，要注意甄别

**注意/.mujoco是隐藏文件夹，在界面中可以打开显示隐藏文件的开关**
# 下载地址 https://github.com/deepmind/mujoco/releases/tag/2.1.0
cd ~/Downloads/
wget https://github.com/deepmind/mujoco/releases/download/2.1.0/mujoco210-linux-x86_64.tar.gz
mv mujoco210-linux-x86_64.tar.gz mujoco210 #这里相当于重命名
tar -zxvf mujoco210-linux-x86_64.tar.gz #这里有问题 应解压重命名后的文件
mkdir ~/mujoco  #这里应改为 mkdir ~/.mujoco 
cp -r mujoco210 ~/.mujoco #复制到~/.mujoco中 
# 添加环境变量
sudo gedit ~/.bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.mujoco/mujoco210/bin
export MUJOCO_KEY_PATH=~/.mujoco${MUJOCO_KEY_PATH}
source ~/.bashrc# 测试
cd ~/.mujoco/mujoco210/bin/
./simulate ../model/humanoid.xml

其余按照原作者的内容进行安装
3.在安装mujoco_py时，我首先遇到作者未出现的报错

解决方法：更换Cython版本
