bash globbing（globstar）模式错误，如果*目录为空，“没有这样的文件或目录”

I have a folder structure as such:

我有一个文件夹结构:

a/
  b/
    test.js
  c/
    another_test.js

When I want to find all these files, I tried the globstar approach:

当我想找到所有这些文件时,我尝试了globstar方法:

ls a/{,**/}*.js

However, this command errors (but still outputs files) because there is no a/*.jsx file:

但是,这个命令错误(但仍然输出文件),因为没有/ * .jsx文件:

$ ls a/{,**/}*.jsx
    ls: a/*.jsx: No such file or directory
    a/b/test.js

I want to use this specific glob because in the future, at some point, a/test.js could exist.

我想使用这个特定的glob,因为在将来某个时候,/ test.js可能存在。

Is there a glob pattern that will find all .js files in a/ recursively and not error?

是否有一个glob模式,可以在/递归中找到所有.js文件,而不是错误?

I looked at some of the options in this question but couldn't find anything that doesn't error and lists all files.

我查看了这个问题中的一些选项,但找不到任何错误并列出所有文件。

With bash4 and above, just use:
ls dir/**/*.js

使用bash4及更高版本,只需使用:ls dir / ** / * .js

With previous bash versions, such as 3.2 shipped with osx, you can use find:
find dir -name '*.js'

使用以前的bash版本,例如3.2附带的osx,你可以使用find:find dir -name'* .js'
