这是日志： 这是实时日志：

但根路径确实存在。

Answer 1

感谢发布这些日志;这里发生的事情是该路径中正在监视的WorkSpaces目录的大小写的问题。这有一些复杂的背景导致守望者需要知道文件名的确切大小，以便我们可以报告仅更改大小写的名称。

TL; DR是您应该要求React Native使用Workspaces作为目录名来观察路径，或者重命名目录以使其实际为WorkSpaces（换句话说，make确保您要求的路径与文件系统的路径完全匹配。

这里有一些守望者的错误，我会在此期间修复：

1. 我们应该在观看的早期阶段使用我们严格的经典来规范这条路径（应该使用这个用例＆＃34;只是工作＆＃34;）
2. 当出现这种不匹配时，我们应该用这个解释来表明这个错误

Answer 2

简而言之：只需将项目所在的包含文件夹重命名为 workspaces（全部为小写），示例如下：
