我做了一个文件上传/下载功能（方便后面Rag里面使用），
文件删除时，调用了st.experimental_rerun() ，报错。
代码
col1, col2, col3, col4 = st.columns([3, 1, 1, 5])
with col1:
st.write(file_name)
with col2:
download_key = f"download_{file_name}"
download_button = st.download_button(
label="Download",
data=open(file_path, "rb"),
file_name=file_name,
mime=file_type,
key=download_key
)
with col3:
# 删除按钮
delete_key = f"delete_{file_name}"
if st.button("Delete", key=file_name):
if delete_file(file_name):
st.success(f"文件 '{file_name}' 已成功删除。")
st.experimental_rerun()
else:
st.error(f"删除文件 '{file_name}' 失败。")

错误：

st.rerun() 用这个试试
