关于gym和universe安装

Question

按照老师简书上的内容，卸载了gym（0.10.5版本），然后 pip install gym==0.9.5

然后再去运行test_universe1.py 又报错了，

你的 Docker 没设置非 root 用户也可以运行吧？因为我在上面的错误里看到了 Permission Denied（权限被否决）

为了让我们之后每次运行 Docker 不需要用 root 身份而只需要用我们的普通用户身份，我们可以这样做：

sudo groupadd docker

上面的命令是为了创建一个用户组，叫做 docker。

然后，我们再把我们当前所在的用户添加到 docker 这个用户组里：

sudo usermod -aG docker $USER

接着，重启一下电脑：

sudo reboot
