无需使用pipfor installation Tkinter(版本 2.x) 或pip3for installation tkinter(版本 3.x)。它们在 Ubuntu 中是本地可用的，您可以同时安装两个版本。从维基百科：

特金特是 Tk GUI 工具包的 Python 绑定。它是 Tk GUI 工具包的标准 Python 接口，2并且是 Python 事实上的标准 GUI。3Tkinter 包含在 Python 的标准 Linux、Microsoft Windows 和 Mac OS X 安装中。

我自己确实需要安装 Pillow（PIL 的分支）来进行图像处理。在这种情况下，您仍然不需要pip或pip3，而是sudo apt install使用。例如，这是我最近安装的：

$ grep " install " /var/log/dpkg.log | grep -i pil
2019-12-02 20:31:46 install python-pil:amd64 <none> 3.1.2-0ubuntu1.1
2019-12-04 16:43:04 install python-pil.imagetk:amd64 <none> 3.1.2-0ubuntu1.1
2019-12-04 16:43:11 install python3-pil.imagetk:amd64 <none> 3.1.2-0ubuntu1.1
2019-12-04 18:59:08 install python-pil-doc:all <none> 3.1.2-0ubuntu1.1
2019-12-04 18:59:10 install python-pil-dbg:amd64 <none> 3.1.2-0ubuntu1.1
2019-12-04 18:59:10 install python-pil.imagetk-dbg:amd64 <none> 3.1.2-0ubuntu1.1

使用 Pillow 成像，您可以在 Tkinter 画布中显示像屏幕截图一样的图像：
