尝试在 Arch Linux 中导入 matplotlib.pyplot 时出现 tkinter 错误

我正在使用 Arch Linux 和 Gnome。我用了点在我的主目录中安装 matplotlib：

pip install --user matplotlib

这似乎有效，当我使用 Python 时，我可以成功import matplotlib。但是，如果我尝试导入，matplotlib.pyplot则会出现错误

>>> import matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/username/.local/lib/python3.7/site-packages/matplotlib/pyplot.py", line 2374, in <module>
    switch_backend(rcParams["backend"])
  File "/home/username/.local/lib/python3.7/site-packages/matplotlib/pyplot.py", line 207, in switch_backend
    backend_mod = importlib.import_module(backend_name)
  File "/usr/lib/python3.7/importlib/__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "/home/username/.local/lib/python3.7/site-packages/matplotlib/backends/backend_tkagg.py", line 1, in <module>
    from . import _backend_tk
  File "/home/username/.local/lib/python3.7/site-packages/matplotlib/backends/_backend_tk.py", line 5, in <module>
    import tkinter as Tk
  File "/usr/lib/python3.7/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: libtk8.6.so: cannot open shared object file: No such file or directory

为什么我会收到错误以及如何修复它？

出现这个问题是因为我没有tk或者特金特安装。安装知识库包解决了这个问题：

pacman -S tk
