使用pynsist打包Streamlit应用为Windows独立可执行文件的启动问题求助

这是我在Stack Overflow的首个提问，若描述存在不清晰的地方，欢迎随时询问更多细节。

我正在为个人项目打包Streamlit应用，开发环境为Linux，但需要部署到Windows系统，目标是生成独立可执行文件，运行后自动打开浏览器标签页展示应用，关闭标签页后程序自动退出。我计划使用pynsist库完成打包（该库我在其他项目中使用过，运行表现稳定）。

我参照相关讨论的建议操作，在Ubuntu上运行正常，用pynsist打包后在Windows上看似能正常运行，实际是可执行文件启动后，没有自动打开浏览器标签页展示应用，手动访问localhost:8501也报连接错误，也没有输出Streamlit初始化日志或报错信息，仅正确打印了当前工作目录。

相关代码与配置 #

项目结构 #

|- installer.cfg
|- src
    |- main.py
    |- run_app.py

main.py #

import streamlit as st

st.title("Test")
st.title("My first app deployed with Pynsist!")

run_app.py（经Thomas K评论后更新的EDIT 2版本） #

import os
import subprocess
import sys

from src.config import EnvironmentalVariableNames as EnvVar, get_env

def main():
    executable = sys.executable
    result = subprocess.run(
        f"{executable} -m streamlit run {os.path.join(get_env(EnvVar.EMPORIO_VESTIARIO_DASHBOARD_WORKING_DIR), 'src', 'main.py')}",
        shell=True,
        capture_output=True,
        text=True,
    )


if __name__ == "__main__":
    main()

其中EMPORIO_VESTIARIO_DASHBOARD_WORKING_DIR是环境变量，用于适配Linux和Windows双系统，Windows下指向程序安装目录。

installer.cfg（pynsist配置文件，已通过pip list补全Streamlit依赖，EDIT 2新增Jinja2的依赖MarkupSafe） #

即便在installer.cfg中加入了Jinja2依赖，Windows安装后启动仍报Jinja2缺失错误，报错栈如下：

EDIT2 #

经Thomas K提示后解决了依赖问题，程序能启动Streamlit，但又出现新问题：启动日志显示Streamlit等待邮箱输入，程序卡住，日志还出现CORS和XSRF配置警告、credentials报错，日志如下：

我尝试在subprocess.run命令中添加--server.headless=false参数没有效果，查到可以添加.streamlit/credentials.toml文件但不清楚Windows下的存放路径。

待解答问题 #

为什么Windows下不能像Linux一样自动启动应用？有没有办法无需用户额外配置就能直接启动应用？
