Python：从 Repl.it 复制到 Visual Studio 的代码无法正确运行：无效参数错误

编程问答 2022-05-24

问题描述

您好，目前我正在 Repl.it 上开发一些 python 脚本，用于设备共享。

但现在考虑到我正在转向 Visual Studio（对于工具箱和其他事项à并且我已经复制了代码，我得到了一个没有任何意义的无效参数代码。

Loaded '__main__'
Loaded 'runpy'

如果代码可以在 repl.it 上运行并且我有相同的文件和文件夹结构..那么为什么这在 Visual Studio 中不起作用？当然，repl.it 有 python 3.8，Visual Studio 有 python 3.7..但这不可能是对的？

已编辑：出于隐私原因删除了代码。

解决方法

您已经从 repl.it 上使用正斜杠 / 来描述文件夹的基于 linux 的文件结构，如 api_request_jsons/fetch_points 转移到本地计算机上基于 Windows 的文件结构（正在运行 Windows），它使用反斜杠 \ 来描述文件夹。所以api_request_jsons/fetch_points需要转换为api_request_jsons\fetch_points。最好的方法是将 os.path.join 与每个嵌套文件夹一起用作参数（即将 api_request_jsons\fetch_points 替换为 os.path.join("api_request_jsons","fetch_points") 以允许您的代码在 *nix 和 Windows 文件系统之间传输。>
