Question

我无法使用python3.5运行matplotlib.pyplot和tkinter。我在Ubuntu 12.04.5 LTS上。我在输入dpkg -l python3-tk时看到安装了python3-tk。我还应该如何排除故障？

python3-tk只适用于python3.2而不是python3.5吗？

以下示例使用python3.2与python3.5

machine:~$ /usr/bin/python3
Python 3.2.3 (default, Jun 18 2015, 21:46:58)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> exit()

machine:~$ /usr/bin/python3.5
Python 3.5.2 (default, Jul 17 2016, 17:38:18)
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
  File "/usr/lib/python3.5/tkinter/__init__.py", line 36, in <module>
    import _tkinter
ImportError: No module named '_tkinter'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.5/tkinter/__init__.py", line 38, in <module>
    raise ImportError(str(msg) + ', please install the python3-tk package')
ImportError: No module named '_tkinter', please install the python3-tk package

已安装python3-tk

Answer 1

sudo apt-get install python3-tk

此命令将仅为您的默认python3安装tkinter，因此python3.5 ImportError。

您可以运行以下命令来安装python3.5

sudo apt-get install python3.5-tk

Answer 2

将matplotlib后端更改为'agg'或其他一些非交互选项。如下所示：

matplotlib.use（ 'AGG'）

Answer 3

python3-tk库是在3.2版本下安装的，而不是3.5版本。卸载了Python3-tk并安装了python3.5-tk

Answer 4

我尝试在ubuntu16.02中使用此命令，

sudo apt-get install python3.5-tk

默认情况下，我安装了python2.7。您可以参考此link
