编译Python程序时matplotlib导入_path遇DLL加载失败问题求助

我开发了一款使用matplotlib绘制数据折线图的Python程序，在PyCharm中运行完全正常，但通过PyInstaller或auto-py-to-exe将其编译为exe文件后，运行exe并触发绘图功能时，出现如下错误：

ERROR:root:

我已经尝试了以下解决方法，但问题仍未解决：

• 执行pip install msvc-runtime
• 重装MS Visual C++ Redistributables（x64和x86版本）
• 确认Windows\System32文件夹中存在matplotlib所需的msvcp140.dll和vcruntime140.dll文件

我无法理解为何程序在IDE中运行正常，编译为exe后却出现该问题，恳请各位提供解决思路。

简化后的核心代码 #

import matplotlib.pyplot as plot


class LineGraph:
    def __init__(self, pairs=[['2023-01-01', 352.76], ['2023-01-15', 725.48]]):
        self.x = []
        self.y = []
        for item in pairs:
            self.x.append(item[0])
            self.y.append(item[1])

    def graph_values_by_date_line(self):    
        plot.rc('xtick', labelsize=8)
        plot.rc('ytick', labelsize=8)

        fig, ax = plot.subplots()
        ax.plot(self.x, self.y, linewidth=1.0, marker='o', markersize=2)
        ax.legend()

        plot.xticks(rotation=90)

        figManager = plot.get_current_fig_manager()
        figManager.window.showMaximized()
        plot.show()

最新使用的PyInstaller编译命令 #

pyinstaller --noconfirm --clean --collect-all matplotlib -i "../resources/icon.ico" --add-data "../resources;resources/" --add-data "../reportlab;reportlab/" --add-data "../gsdll64.dll;gsdll64.dll" --add-data "../gsdll64.lib;gsdll64.lib" --add-data "../gsprint.exe;gsprint.exe" --add-data "../gswin64.exe;gswin64.exe" --add-data "../gswin64c.exe;gswin64c.exe" --distpath "./output" ../WeeklyGiving.py
