如何解决 toml.decoder.TomlDecodeError: 键组本身不在一行。 (第1行第1列...)调用streamlit包时出错？

我刚刚安装了streamlit 软件包。当我尝试运行“streamlit hello”时，出现以下错误：

(base) C:\>streamlit hello Traceback (most recent call last):

有谁知道如何解决这个错误？

先感谢您！

当我尝试运行“streamlit”命令时，我也遇到了同样的错误。

因此，我所做的就是完全跟踪代码，看看从哪里可以找到这个“config.toml”，然后简单地删除了该文件。

Windows 中“config.toml”文件的路径是：C:users/{username}/.streamlit/config.toml

删除该文件即可解决该错误。
