我创建了一个简单的 ML 仪表板应用程序，我想使用 Heroku 部署它。我使用 Streamlit 来开发仪表板。仪表板在本地执行时正常运行。
当我使用 Heroku 运行它时，我收到以下日志/错误：

我的Procfile 看起来不错：
web: sh setup.sh && streamlit run app.py
这是 setup.sh 代码：
mkdir -p ~/.streamlit
echo "\
[genera]\n\
email = \"dorrego.cabrera@gmail.com\"\n\
"> ~/.streamlit/credentials.toml
echo "\
[server]\n\
headless = true\n\
enableXsrfProtection = false\n\
enableCORS = false\n\
port = $PORT\n\
" > ~/.streamlit/config.toml
代码似乎安装了两次 Streamlit。有人能解释一下原因吗？
