我尝试在windows 10上通过Pycharm IDE使用matplotlib包。 当我运行这段代码时:

from matplotlib import pyplot

我得到以下错误:

ImportError: No module named 'tkinter'

我知道在python2中。它被称为Tkinter,但这不是问题-我只是安装了一个全新的python 3.5.1。

编辑:此外,我还尝试导入'tkinter'和'tkinter' -这两个都不工作(都返回了我提到的错误消息)。

我在Win x86/64上也遇到了同样的问题,因为我的自定义Python3.7安装不包括Tcl包,所以只需修改或重新安装python即可

其他回答

如果你有pip(你可能有),在Windows上打开cmd或powershell,或者在OS X或Linux上打开终端窗口,然后尝试这样做(如果你在Windows上,请确保python在系统路径中):

pip install tkinter

安装tkinter需要一段时间,然后尝试执行以下代码块:

from tkinter import *
root = Tk()
# Your code goes here 
root.mainloop()

希望这能有所帮助!谢谢你!

Almost all answers I searched for this issue say that Python on Windows comes with tkinter and tcl already installed, and I had no luck trying to download or install them using pip, or actviestate.com site. I eventually found that when I was installing python using the binary installer, I had unchecked the module related to TCL and tkinter. So, I ran the binary installer again and chose to modify my python version by this time selecting this option. No need to do anything manually then. If you go to your python terminal, then the following commands should show you version of tkinter installed with your Python:

import tkinter
import _tkinter
tkinter._test()

为像我这样的穷人使用python 3.7。您需要python3.7-tk包。

安装python3.7-tk

$ python
Python 3.7.4 (default, Sep  2 2019, 20:44:09)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tkinter'
>>> exit()

请注意。安装Python3-tk。但不是python3.7-tk。
