运行azure函数时路径中的非法字符

运行azure函数时路径中的非法字符

Chr*_*all 2 c# visual-studio azure-functions

所以我有一个整天都在工作的azure函数。大约二十分钟前，我在尝试单击 Visual Studio 中的运行按钮时开始出现错误。它成功构建，然后在启动时显示并出错，只是指出“路径中的非法字符 - Visual Studio”。我检查了 git 日志并且没有进行任何更改，所以我真的不确定出了什么问题。

我附上了问题的 gif 来尝试说明问题。

我真的尝试了我能想到的一切。这是我所采取的所有步骤的列表。

重启机器
重新克隆 repo
重新安装 Visual Studio 2017 和 2019
删除了 appdata 文件夹
清除缓存文件
浏览调试菜单
系统恢复

这似乎不是该功能的问题，因为团队的其他成员似乎没有遇到相同的问题并且可以成功运行该功能。所以我假设它是一个系统问题。

更新： 对于遇到此问题的任何人，我终于找到了解决方法

非常感谢 Tsuyoshi Ushio over medium，请按照以下步骤解决问题似乎是当 %appdata%/local 文件夹中的 azure 功能工具文件处于错误状态时
