伯克利PacMan项目Tkinter.TclError中的Tkinter问题：没有显示名称和$display环境变量

Question

抱歉问了一个愚蠢的问题

在尝试在conda中设置一个venv、设置我自己的自定义venv、两次重新安装Python 2.7.18、重新启动等等之后，当我尝试从Berkeley运行pacman代码时，仍然会遇到这个问题

有没有关于为什么会这样的提示

Tkinter在Python2.7中应该是固有的，所以我不知道为什么它会在我身上出现。 即使在C://Python27文件夹中使用了python2.7的exe，我仍然会遇到问题

我使用的IDE是PyCharm

Traceback (most recent call last):

    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

任何帮助都将不胜感激
