虚拟机安装不赘述了，使用版本为ubuntukylin-16.04-desktop-amd64（建议使用ubuntu而不是centos）。
安装过程很容易，按着顺序依次确定即可，安装完成之后需要进行网络配置，让我们的虚拟机链接上网络。
一、配置网络
1.打开VMware workstation ，菜单栏选项–>编辑–>虚拟网络编辑器，将VMnet8设置为NAT模式，启动DHCP(DHCP就是用来动态分配虚拟机IP的，不启用也没有关系), 如图：
2.在主机上开启NAT服务和DHCP服务：
win+r –> services.msc
3.然后，打开VMware workstation ，菜单栏选项–>虚拟机–>设置为NAT模式
4.更改适配器设置，将可以上网的网络设置为共享，共享给虚拟机的VMnet8（不需要勾下面的勾）:
二、配置Python3环境
ubuntu的kylin16系统自己带了Python2.7和Python3.5环境，我需要使用Python3.8+。
1.配置依赖环境，如果不进行这步可能会出现一些问题。
2.去官网下载Python-3.8.1.tar.xz
3.解压下载的包
tar -xvJf Python-3.8.1.tar.xz
4.进入解压后的目录
cd Python-3.8.1/
5.安装依赖(非必要，可跳过此步骤，如在6步出错在执行本步骤)
执行下列命令安装依赖过程中，如有提示，一律y。
sudo apt-get install python-dev
sudo apt-get install libffi-dev
sudo apt-get install libssl-dev
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev
6.执行安装
./configure prefix=/usr/local/python3
sudo make && sudo make install
7.修改软连接（配置全局变量）
将原来的链接备份。
sudo mv /usr/bin/python /usr/bin/python.bak
添加python3的软链接。
sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python
测试是否安装成功了。
python -V
8.安装/升级pip
这句是给(python2.7安装pip)
sudo apt-get install python-pip
给python3安装pip。
sudo apt-get install python3-pip
执行升级。
sudo pip install --upgrade pip
sudo pip3 install --upgrade pip
升级pip时出现了问题：
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
from pip import main
修改一下pip配置
sudo vi /usr/bin/pip
改成
#原PIP配置文件
from pip import main
if __name__ == '__main__':
sys.exit(main())
#修改为
from pip import __main__ //修改
if __name__ == '__main__':
sys.exit(__main__._main())//修改
9.pip3安装包时出现问题
Traceback (most recent call last):
File "/usr/bin/pip3", line 11, in <module>
sys.exit(main())
File "/home/fulequn/.local/lib/python3.5/site-packages/pip/__init__.py", line 11, in main
from pip._internal.utils.entrypoints import _wrapper
File "/home/fulequn/.local/lib/python3.5/site-packages/pip/_internal/utils/entrypoints.py", line 4, in <module>
from pip._internal.cli.main import main
File "/home/fulequn/.local/lib/python3.5/site-packages/pip/_internal/cli/main.py", line 57
sys.stderr.write(f"ERROR: {exc}")
原因
查了很多，大多数老外的说法是，高版本的pip不再支持python3.5
解决
移除pip的相关文件
sudo apt autoremove
下载pip的安装文件
url -O https://bootstrap.pypa.io/pip/3.5/get-pip.py
执行安装文件
/usr/bin/python3 get-pip.py
这句是给(python2.7安装pip)
sudo apt-get install python-pip
给python3安装pip。
sudo apt-get install python3-pip
pip升级
sudo pip install --upgrade pip
sudo pip3 install --upgrade pip
这个部分我卸载之后，出现了pip不存在的错误。之后重新安装，再升级就解决了。
三、安装OpenAI gym
输入下面语句，安装gym
pip install gym -i https://pypi.tuna.tsinghua.edu.cn/simple
1.出现下面错误
ModuleNotFoundError: No module named '_ctypes'
解决：
sudo apt install libffi-dev -y
2.出现错误
ERROR: No matching distribution found for gym[all]
未解决
3.出现错误
