Python 仅使用grid Tkinter，但仍会出现错误

所以我刚开始使用Google Colab，我不断发现这个错误：

TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

我试图制作一个GUI窗口，从用户那里接收信息并保存它

我在网上读到的所有信息都表明，问题在于我使用的是

pack（）

和

grid（）

，但我只使用

grid（）

。当我第一次尝试放置标签（

sourceLabel

）时，错误开始

我很困惑，任何帮助都会很好

这是一个非常奇怪的错误，我只是使用canvas和pack方法重新编写了代码，而不是使用网格、行和列。请确保您使用的是Python3x，这样就不会出现这些奇怪的错误，希望这能有所帮助，您可以在底部使用x和y值，在设置画布时，您可以在顶部使用高度和宽度值。快乐编码

global path, source, recoding  # Global Values so that save_info can get the values
# Creates window
root = Tk()
root.title("File Information")

# We would now do l = Label(text="Test") 
# canvas.create_window(20, 30, anchor="nw", window=l)
canvas = Canvas(width=400, height=300)
canvas.pack(fill="both", expand=True)

我无法用您问题中的代码重现几何体管理器问题。关闭最后一行的

window.destroy（）

调用上的应用程序窗口时，我遇到了另一个错误（因为此时应用程序窗口已被禁用。您是如何使错误出现的？您也不需要

window.destroy（））

结尾。您发布的代码不能给出您所说的错误。请将此代码复制并粘贴到新文件中，运行它，然后向我们显示错误的完整堆栈跟踪。这些小部件是否要在根窗口以外的窗口中创建？创建小部件时，请尝试指定父级（

窗口

）。
