button_frame.pack(fill='x')

root.mainloop()

您遇到的错误是由于您尝试在同一父小部件（根）中使用包和网格几何管理器。在 Tkinter 中，每个父小部件只能使用一个几何管理器。

import tkinter as tk

root = tk.Tk()

fnt = 'Arial'

root.title('Text Editor')
root.geometry('800x500')

ttl = tk.Label(root, text='Text Editor', font=('Arial', 25), height=3) 
ttl.pack(padx=10, pady=20)

text = tk.Text(root, font=(fnt, 16))
text.pack(padx=0, pady = 10)

button_frame = tk.Frame(root)
button_frame.pack(fill='x')

arial = tk.Button(button_frame, text='Arial', font=('Arial',10), height=1)
arial.grid(row=0, column=0, sticky=tk.W+tk.E)

root.mainloop()
