您好我正在尝试获取以下github回购：https://github.com/lukekulik/solar-system
在我的笔记本电脑上工作并安装了所需的所有模块但由于某些原因，当我尝试运行时我得到错误无法在vis中导入模块from vis import ...。
它在每个文件中，我使用python 3.6。
一个文件的代码如下：
from vis import scene, label, vector, norm, cross
尝试导入wx
时尝试导入vis时出现错误#from pygame.mixer import music
from parameters import planets, n, am
from wx import Exit

ship):

press and hold for smooth transition)
