我制作了一个流线型应用程序作为预测程序的前端，然后我创建了一个 pyinstaller 可执行文件来运行该应用程序。当我运行可执行文件时出现问题，我收到以下错误：pkg_resources.DistributionNotFound: The 'streamlit' distribution was not found and is required by the application使用此回溯：

Traceback (most recent call last):
  File "main.py", line 8, in <module>

pkg_resources.DistributionNotFound: The 'streamlit' distribution was not found and is required by the application
[48095] Failed to execute script main

该文件是使用以下命令创建的：pyinstaller --onefile -w main.py

这是在 Conda 环境中使用 python 3.5.6 在 macOS Catalina 上设置的

如果有任何我可能遗漏的细节可以对此有所帮助，请告诉我。

看起来您需要添加一个hook名为hook-streamlit.py以下内​​容的文件

from PyInstaller.utils.hooks import copy_metadata

datas = copy_metadata('streamlit')

您还需要将--additional-hooks-dir标志传递给您的pyinstaller命令。

如果您已将挂钩文件放在与您的 python 脚本相同的目录中，您可以像这样指定它

pyinstaller --onefile --additional-hooks-dir=. -w main.py
