在 macos 上使用 py2app 导入熊猫时出现问题

如何解决在 macos 上使用 py2app 导入熊猫时出现问题

当我使用带有选项 -An 的 py2app 时，一切正常。 但是没有我在导入熊猫时出错。 我尝试了一个示例代码：

import sys
from PyQt5.QtWidgets import QApplication,QWidget
import pandas as pd

def main():
    df = pd.read_csv("data.csv")
    app = QApplication(sys.argv)
    file = "theme.stylesheet"
    w = QWidget()
    w.resize(250,150)
    w.move(300,300)
    w.setwindowTitle('Simple')
    with open(file,'r') as fh:
        w.setStyleSheet(fh.read())
    w.show()

    sys.exit(app.exec_())


if __name__ == '__main__':
    main()

然后python setup.py py2app

使用 setup.py：

from setuptools import setup

APP = ['main.py']
OPTIONS = {'argv_emulation': True}
DATA_FILES = ['theme.stylesheet','data.csv']
setup(
    app=APP,data_files=DATA_FILES,options={'py2app':OPTIONS},setup_requires=['py2app']
)

但是我有这个错误：

我尝试使用 pyinstaller，但是当我打开应用程序时立即关闭。

如果我在 Windows 上使用它，它工作正常，但在我需要的 macos 中却没有。

我也尝试将 pandas 放在 setup.py 的包中并包含但仍然不起作用。

解决方法

我解决了这个问题，将 python 降级到 3.6 到 3.9。
