我的 setup.sh 文件如下：

mkdir -p ~/.streamlit/

echo “\
[general]\n\
email = \”[e-mail]\”\n\
“ > ~/.streamlit/credentials.toml

echo “\
[server]\n\
headless = true\n\
enableCORS=false\n\
port = $PORT\n\
“ > ~/.streamlit/config.toml

我的Procfile如下：

sh setup.sh && streamlit run dvh-app2.py

我的 requirements.txt 文件如下：

streamlit==0.49.0
bokeh==2.0.1
pandas==0.24.2
numpy==1.17.3

【参考方案1】：

好的，我自己想通了： 问题出在我的 setup.sh 文件上。像这样重新格式化后：

mkdir -p ~/.streamlit

echo "[server]
headless = true
port = $PORT
enableCORS = false
" > ~/.streamlit/config.toml

它没有任何问题。
