Question

我制作了一个精简的应用程序以充当预测程序的前端，然后创建了一个pyinstaller可执行文件来运行该应用程序。运行可执行文件时出现问题，出现以下错误：pkg_resources.DistributionNotFound: The 'streamlit' distribution was not found and is required by the application，具有此追溯：

Traceback (most recent call last):
  File "main.py", line 8, in <module>
  File "<frozen importlib._bootstrap>", line 968, in _find_and_load
  File "<frozen importlib._bootstrap>", line 957, in _find_and_load_unlocked

  File "site-packages/pkg_resources/__init__.py", line 781, in resolve

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

如果有任何我可能错过的详细信息对此有所帮助，请告诉我。

您似乎需要添加一个名为hook的{{1}}文件，其中包含以下内容

hook-streamlit.py

您还需要将from PyInstaller.utils.hooks import copy_metadata datas = copy_metadata('streamlit')标志传递给--additional-hooks-dir命令。

如果将钩子文件放置在与python脚本相同的目录中，则可以这样指定

pyinstaller

在pyinstaller可执行程序中找不到Streamlit发行版
