Tcl没有正确安装

Question

我是一个新用户，使用Pycharm对海龟图形进行简单测试

import turtle as t
tu = t.Turtle()
for _ in range(15):
    tu.forward(5)
    tu.penup()
    tu.forward(5)
    tu.pendown()

但是，当我运行这些代码时，它们出现了以下错误：

  ..._tkinter.TclError: Can't find a usable init.tcl in the following directories: 
{C:\Program Files (x86)\Tcl\lib\tcl8.3} {C:/Program Files (x86)/Tcl/lib/tcl8.6} C:/Users/User/AppData/Local/Programs/Python/Python39/lib/tcl8.6 C:/Users/User/AppData/Local/Programs/Python/lib/tcl8.6 C:/Users/User/AppData/Local/Programs/lib/tcl8.6 C:/Users/User/AppData/Local/Programs/Python/library C:/Users/User/AppData/Local/Programs/library C:/Users/User/AppData/Local/Programs/tcl8.6.9/library C:/Users/User/AppData/Local/tcl8.6.9/library

    This probably means that Tcl wasn't installed properly.

我已检查这些文件和文件夹是否存在。有人能建议我怎么解决这个问题吗？谢谢
