When executing exe file: ImportError: matplotlib is required for plotting when the default backend "matplotlib" is selected when executing exe file

Question

我使用 pyinstaller 创建了一个 .exe 文件。当我运行它在 Pycharm 上时，它工作得很好。但是当我尝试运行可执行文件时发生错误。

这是完整的错误：

Traceback (most recent call last):
  File "DT_070621.py", line 397, in <module>
  File "DT_070621.py", line 315, in arquivos_saida
  File "pandas\plotting\_core.py", line 892, in __call__
  File "pandas\plotting\_core.py", line 1814, in _get_plot_backend
  File "pandas\plotting\_core.py", line 1754, in _load_backend
ImportError: matplotlib is required for plotting when the default backend "matplotlib" is selected.
[11304] Failed to execute script 'DT_070621' due to unhandled exception!

但是当我检查 matplotlib 版本时，一切似乎都很好。

>>> import matplotlib
>>> matplotlib.__version__
'3.4.3'

我还检查了正在使用的后端：

>>> import matplotlib.pyplot as plt
>>> plt.get_backend()
'TkAgg'

我也试过像这样创建 .exe 文件：

pyinstaller --hidden-import=openpyxl --hidden-import=matplotlib --onefile DT_070621.py

但是没有解决我的问题

我也查看了 this question，但它的描述似乎不完整，没有对帮助我解决这个问题有用的答案。

这是我脚本中的导入：

import xml.etree.ElementTree as ET
from xml.etree import ElementTree
import pandas as pd
from shapely.geometry import Point, Polygon
import numpy as np
import matplotlib.pyplot as plt
import os

这是怎么回事，我该如何解决？

Answer 1

添加 --hidden-import pandas.plotting._matplotlib 解决了。
