Can't locate File/Glob.pm in @INC (@INC contains: D:/tools/lib .) at directory.pl line 2

I get this error when running my perl code

Can't locate File/Glob.pm in @INC (@INC contains: D:/tools/lib .) at directory.pl line 2.

line 2: @files=<*>;

When i run the command, I get,

Y:\perl\开发者_开发百科perl>perldoc -l File::Glob

D:\tools\lib\perl\510\File\Glob.pm

So I think the File::Glob module is installed?

@INC should be set correctly upon installation of Perl. When it doesn't match your configuration, you seem to have messed up something.

However, if the current value of @INC doesn't fit your needs, you have various options:

1. Add D:\tools\lib\perl\510\ to the environment variable PERL5LIB (or PERLLIB if this doesn't work)
2. Specify @INC on startup: perl -I D:\tools\lib\perl\510\
3. Instead of writing use libname, you can write use path/to/libname

4. Using a BEGIN block before the use statements:

   BEGIN {
     push @INC,"D:\tools\lib\perl\510\";
   }
