ImportError: No module named '_tkinter', please install the python3-tk package

Question

我已经解决了这方面的所有类似问题并尝试了那里提出的解决方案。但是我无法解决这个错误，尽管我的 python3-tk 包安装在我用于我的项目的正确 virtualenv 中。

虽然在我的项目中，我没有使用 tkinter，但当我尝试运行文件时，我收到以下与 _tkinter 模块相关的错误。

Traceback (most recent call last):
File "/usr/lib/python3.5/tkinter/init.py", line 36, in import _tkinter
ImportError: No module named '_tkinter'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

File "/usr/lib/python3.5/tkinter/init.py", line 38, in raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package

因此，我导航到我的解释器的位置并创建了一个 virtualenv 并使用以下

安装了 python3-tk 包

sudo apt-get install python3-tk

当我检查时，所有的包似乎都是最新的

但我仍然遇到相同的导入错误 ImportError: No module named '_tkinter', please install the python3-tk package。

如有任何建议，我们将不胜感激。

Answer 1

当您导入 matplotlib 时，它可能会尝试使用 tk 后端作为默认后端。如果您没有安装 tk，或者您不想在项目的其他任何地方使用它，那么一个可能的解决方案是简单地使用不同的后端：

import matplotlib
matplotlib.use("agg")
import matplotlib.pyplot as plt

Answer 2

该消息表明，当您运行 sudo apt-get install python3-tk 它告诉您 tkinter 已安装 Python3.6.5，但在另一方面，ImportError 与 Python3.5 有关。所以我相信这应该可以解决您的问题：

sudo apt-get install python3.5-tk

ImportError: No module named '_tkinter', please install the python3-tk package

ImportError: No module named '_tkinter', please install the python3-tk package
