This usually occurs when your current directory does not exist anymore. Most likely, from another terminal you remove that directory (from within a script or whatever). To get rid of this, in case your current directory was recreated in the meantime, just cdto another (existing) directory and then cdback; the simplest would be: cd; cd -.
当您的当前目录不再存在时，通常会发生这种情况。最有可能的是，从另一个终端中删除该目录（从脚本中或其他任何内容中）。为了摆脱这种情况，如果您的当前目录在此期间被重新创建，只需cd到另一个（现有）目录然后cd返回；最简单的是：cd; cd -.

Yes, cd; and cd - would work. The reason It can see is that, directory is being deleted from any other terminal or any other program and recreate it. So i-node entry is modified so program can not access old i-node entry.
是的，光盘；和 cd - 会工作。它可以看到的原因是，目录正在从任何其他终端或任何其他程序中删除并重新创建。因此 i-node 条目被修改，因此程序无法访问旧的 i-node 条目。

Just change the directory to another one and come back. Probably that one has been deleted or moved.
只需将目录更改为另一个目录并返回。可能那个已经被删除或移动了。

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?
碰巧，这是否发生在使用 OverlayFS（或其他一些特殊文件系统类型）的目录上？
I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwdwhich has issues with OverlayFS. I found information about this here:
我刚刚遇到了这个问题，我的交叉编译版本的 bash 将使用一个内部实现，getcwd该实现的OverlayFS 有问题。我在这里找到了有关此的信息：
It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

这似乎可以追溯到 bash 中 getcwd() 的内部实现。交叉编译时，它不能检查getcwd() 对malloc 的使用，因此谨慎并设置GETCWD_BROKEN 并使用getcwd() 的内部实现。这个内部实现似乎不适用于 OverlayFS。

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes(if you're actually building bash and your C library does malloc a getcwd call).
您可以使用bash_cv_getcwd_malloc=yes（如果您实际上是在构建 bash 并且您的 C 库执行 malloc 一个 getcwd 调用）来配置和重建 bash 。
