在 macOS 上使用 py2app 导入 pandas 时出现问题

Question

当我使用带有选项 -An 的 py2app 时，一切正常。但是没有 pandas 导入时我有错误。我尝试一个示例代码：

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

与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。

如果我通过 Windows 使用它，那工作正常，但在我需要的 macos 中没有。

我也尝试将 pandas 放入 setup.py 的包中，但仍然无法正常工作。

我通过 3.9 将 python 降级到 3.6 解决了这个问题。
