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)。


当前回答

在CentOS 7和Python 3.4上,命令为sudo yum install python34-tkinter

在Redhat 7.4和Python 3.6上,命令是sudo yum install rh-python36-python-tkinter

其他回答

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

在CentOS 7和Python 3.4上,命令为sudo yum install python34-tkinter

在Redhat 7.4和Python 3.6上,命令是sudo yum install rh-python36-python-tkinter

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()

也许你从源代码安装了python。在这种情况下,您可以重新编译支持tcl/tk的python。

从http://www.tcl.tk/software/tcltk/download.html编译并安装tcl/tk,我假设你在/home/xxx/local/tcl-tk/安装python。

# install tcl
wget -c https://prdownloads.sourceforge.net/tcl/tcl8.6.9-src.tar.gz
tar -xvzf tcl8.6.9-src.tar.gz
cd tcl8.6.9
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install

# install tk
wget -c https://prdownloads.sourceforge.net/tcl/tk8.6.9.1-src.tar.gz
tar -xvzf tk8.6.9.1-src.tar.gz
cd tk8.6.9.1
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install

使用tcl/tk重新编译python,例如:

# download the source code of python and decompress it first.

cd <your-python-src-dir>
./configure --prefix=/home/xxx/local/python \
 --with-tcltk-includes=/home/xxx/local/tcl-tk/include \
 --with-tcltk-libs=/home/xxx/local/tcl-tk/lib
make 
make install

对于Windows用户,无需再次下载安装程序。只需要做以下几点:

进入开始菜单,输入应用程序和功能, 在搜索框中搜索“python”, 选择Python版本(例如Python 3.8.3rc1(32位))并单击修改, 在“修改设置”页面单击“修改”, 勾选td/tk和IDLE复选框(这会安装tkinter),然后单击下一步。

等待安装,您就完成了。
