Question

我安装了MongoDB perl模块。

我有一个简单的perl脚本（下面）：

 use MongoDB ();
 print "OK!\n";

当我编译这个perl脚本时，我收到以下错误：

"all" is not exported by the List::Util module
Can't continue after import errors at /usr/local/share/perl5/Specio/OO.pm

在 /usr/local/share/perl5/Specio/OO.pm 第9行，有以下使用声明。

use List::Util qw( all );

我相信上面的行是所有错误的原因，因为它们似乎是嵌套在这个文件中。

如何解决此错误？

可能存在递归调用导出例程 qw(all) 的模块。

/usr/local/share/perl5/Specio/OO.pm 第 9 行调用以下导出的方法：

use List::Util qw( all );

这个方法也可以被第 2 行 script.pl 中使用的模块调用。

Compilation failed in require at script.pl line 2.

在代码块中使用 require 代替使用 List::Util qw( all );在 script.pl 第 2 行的给定模块中，仅在需要的地方。

这可能会解决您面临的问题。
